Authors: Singh H.P. , Srivastava S.K. , Roy S.K.
Published: September 2022

The present paper describes mio- and macrospores obtained from the Umia-beds (Uppermost Gondwana horizon) in Cutch (W. India). They are referred to 48 genera and 82 species, of which four genera viz. Baculareticulosporis, Crassimonoletes, Umiaspora, Auriculozonospora, and 40 species are new. The spore-flora is rich in pteridophytic spores and coniferous pollen grains. It has been compared with the other known assemblages from comparable strata. Finally, a discussion on the probable age of Umia-beds, based on the study of Sporae dispersae, has been given indicating that these beds closely correspond to the Wealden (Lower Cretaceous) age.

Studies in the Glossopteris flora of India - 31. Some remarks on the genus Glossopteris sternb
Authors: Maheshwari H.K
Published: September 2022

The genus Glossopteris so abundant in the southern Palaeozoic flora has neither been properly circumscribed nor correctly delimited into species so far. The reason for this is a complete lack of accepted criteria on which to base these delimitations. In the present paper, the views expressed and the work done so far on this problem have been summarized. On the basis of the study of several hundred specimens from the Barakar and Raniganj stages as well as a survey of published literature some suggestions have been put forth for bringing harmony in the specific circumscription within this genus.
On the Palaeozoic pteridophylls
Authors: Zimmermann Walter
Published: September 2022

The Palaeozoic pteridophylls hold an excellent intermediate position in their entity as well as in their individual characteristics between the oldest (silurian and early devonian) plants and the land plants of today. This is also illustrated by the genera as they were named by Brogniart as follows: Archaeopteris, Sphenopteris, Pecopteris, Neuropteris, Linopteris, Alethopteris, Callipteris.

These genera demonstrate how the phylogenetic development was carried out by few elementary processes, still isolated and restrained to primitive stages. The same elementary processes also formed the structure of palaeozoic stems in their primitive stages.

The mesozoic pteridophylls are a further step of phylogenetic changes towards present day leaf forms.
The nature and relationships of the Tertiary Brown coal flora of the Yallourn area in Victoria, Australia
Authors: Duigan Suzanne L.
Published: September 2022

To date, sixteen taxa from the brown coal have been identified satisfactorily. Almost all of these had a wider distribution in Australia during the Tertiary period than they do at present, and only about half of them still occur in Victoria. A search for comparable modern floras shows that all sixteen taxa are still represented in New Guinea. with somewhat smaller numbers in New Caledonia. part of the eastern Australian coast and northern New Zealand. The nature of these modern floras and the climatic conditions under which they occur suggest that the brown coal vegetation consisted mainly of Nothofagus rain forests and gymnosperm or mixed gymnosperm-broadleaf forests, possibly with some overlap between these types, and that the rainfall was high and the temperatures were moderate.

Pollen analysis has shown that, with the exception of the Lauraceae and Oleaceae (the vertical distribution of which is not known) and the Restionaceae/Centrolepidaceae (which only occurs at the top of the coal), the taxa concerned occurred throughout the period of formation of the coal, but that their relative abundance varied considerably Nothofagous pollen dominates the diagram as a whole. with values of up to 95%, and when the few low values for this genus are recorded the values for one or more of Casuarina, Myrtaceae and Gymnosperms are high. Complex changes in the diagram suggest a major change in environmental conditions at about the middle of the coal-forming period, with the possibility that conditions were much less stable during the second half of this period.
The present position and problems of Tertiary palaeobotanist in India
Authors: Lakhanpal R.N.
Published: September 2022

Since the second quarter of the nineteenth century, when fossil plants began to be collected in India, almost all the earlier work in Indian palaeobotany was carried out on Mesozoic and Palaeozoic fossils. Progress in Tertiary palaeobotany really started in the early thirties of the present century. The contributions have mainly been on the structure of individual fossils, mostly petrifactions, from the Deccan Intertrappean beds and from the Middle Tertiary strata of Assam and South India. Of late, some papers on the leaf impressions and pollen and spores have also appeared. At the present stage it is desirable that Tertiary plants are studied collectively as floras. This will help in solving a number of problems related to stratigraphy, palaeogeography and palaeoecology during the Tertiary period in India.
Evolutionary trends in the palmae with special reference to fossil plams
Authors: Mahabale T.S.
Published: September 2022

The paper gives an account of the characters generally used in determining the relationships of living palms and their classification. It tries to evaluate the utility of such characters in the identification and phylogeny of fossil palms by citing suitable examples. Many morphological characters of palms are conservative and are helpful within a limited range: others are unhelpful, especially anatomical features of isolated parts of unknown identity. Therefore, in building up any classificatory system of fossil palms, all available characters of as many parts as are available should be utilized within the range of their variability. To achieve this purpose, they have to be studied in detail in the same or related genera of living palms and then correlate them with those in the fossil palms. Such a comprehensive method alone would be helpful in determining the phylogeny of fossil palms.
Some studies on the Tertiary deposits of Nigeria, West Africa
Authors: Puri G.S.
Published: September 2022

Fossil leaves of Palms, Terminalia and Combretum have been described for the first time from tin mines of the Jos Plateau in Nigeria. These show affinities with modern vegetation of West Africa. However, Terminalia and Palms seem to have shifted away from the Jos Plateau, which at present has a dominant vegetation of Scrubby and Grassy growth. This is explained to be due to changes in the Soil and Climatic conditions. Some soil studies from the Jos Plateau are presented. The fossils are Terminaliophyllum keayi (new species), T. faggei (new species) and Combretophyllum josiensis (new species).
The distribution of Densospores
Authors: Butterworth M.A.
Published: September 2022

Densospores include species of the miospore genera Cingulizonates (Dybova & Jachowicz), Cristatisporites (Potonie & Kremp), Densosporites (Berry) and Radiizonates Staplin & Jansonius from the literature of Europe and North America, and Euryzonotriletes Naumova, Hymenozonotriletes Naumova and Trematozonotriletes Naumova from the Russian literature. An account is given of the taxonomic position of densospores and of their morphographic variation in different parts of the column.

Densospores have been recorded in large numbers, mainly from coal seams, from the Devonian to the Permian of the northern hemisphere. The geographical distribution of these occurrences forms the subject matter of the present paper. In general, densospores first occur in abundance in more northerly regions and are displaced gradually southwards during the Carboniferous. They are most common and have the longest ranges, in area of slow subsidence.
Early Permian Vesiculate Pollen from Texas, U.S.A.
Authors: Tschudy Robert H. , Kosanke Robert M.
Published: September 2022

Twenty-five vesiculate pollen types and related taxa of Early Permian age is reported, and the new taxa are described.

The genera identified are: Alisporites, Complexisporites, Endosporites, Florinites, Hamiapollenites, Nuskoisporites, Pilyosporites, Platysaccus, Potonieisporites, Schizaeoisporites, Striatites, Strotersporites, Sulcatisporites, Vesicaspora, Vestrigisporites, Vittatina and Wilsonites.

Vesiculate pollen taxa increased rapidly in Early Permian time. with this increase it is not surprising to observe considerable morphologic diversity. For example, Vittatina (LUBER) Wilson, 1962, lacks vesicles. Specimens corresponding to Vittatina morphologically but possessing definite rudimentary sacci are herein described. These specimens are the basis for a new genus named Costapollenites.  

The pollen of Vittatina, Hamiapollenites and Costapollenites all possess a costate or ribbed proximal surface, which in proximal view may resemble the pollen of Ephedra and Welwitschia. However, Vittatina, Hamiapollenites and Costapollenites differ from Ephedra and Welwitschia in that their costae are restricted to their proximal surfaces although they may possess distal bands at right angles to the proximal costae.

Pollen Morphology of Angiosperms and Palaeofloristic areas and provinces at the boundary of the Cretaceous and Paleogene
Authors: Zaklinskaia E.D.
Published: September 2022

The establishment of natural affinity between ancient angiosperms and taxa of recent flora can be based on palynomorphological studies. The structure, number and distribution of apertures are important features.

At the beginning of the Late Cretaceous period angiosperms had pollen with primitive but already distinct apertures. Their relationship with Salicales, Fagales, Platanales, Eucommiales (?), can be established.

During the Late Cretaceous, pollen type with syncolpate apertures (Duplospores-Sporopollis-Sincolporites) become differentiated, which may be linked with the Santalales, Myrtales and Sapindales. In the Upper Senonian-Paleocene pollen with extremely complicated and varied apertures become differentiated partially with inequipolar symmetry (Aquilapollenites, Pentapollenites, Pemphixipollenites, Betpakdalina, Kryshtofoviana, Porotrichotomosulcales types). Some taxa of these may be associated with the families Loranthaceae, Olacaceae, Simarubaceae, Palmae (?), Euphorbiaceae etc. Genera and species included above have narrow stratigraphic ranges and distinctly outlined areals.

To the same period belongs the differentiation of pollen type with a three-equatorial aperture (Normapolles, Proteacidites, Triorites and Triatriopollenites), which are links with morphological types of pollen of Proteaceae, Myricaceae, Casuarinaceae Fagaceae, Rubiaceae Ulmaceae, Juglandaceae and Betulaceae.

With the help of morphological groups, we succeeded to establish sequential stages and phases in the history of the development of angiosperm flora and determine their role in the formation of botanical-geographical regions and provinces. During the Late Cretaceous-Paleogene boundary period relationship is established between Pacific and Atlantic floristic areas of Eurasia on one hand the North America and the continents of the Southern Hemisphere on the other.
The deadlock in Pleistocene Palaeobotany
Authors: Macko Stephan
Published: September 2022

It seems to me to be necessary to give some remarks as a commentary to my article, since the attitude of some European scientists toward the problem discussed in my paper is (considering the second half of the twentieth century) a rather particular one. I have encountered the following opinions and remarks: " It is known that the diluvial theory of Penck and Bruckner is ambiguous, but one cannot agree with the hypotheses given in the article “, .  . or" It is true that many scientists tried to find a correlation between the glaciations in Alpes and the remaining part of Europe (A. K. Wells, W. B. Wright, L. J. Wills, J. F. Kirkaldy), and that they have stated many contradictions, nevertheless the explanation of these contradictions given in the article is hardly accepted " ..., or "The attempts of shaking the diluvial theory of Penck and Bruckner are not friendly accepted by the scientists, being not supported by most of them". According to my opinion, such attitudes, luckily not general ones, are anti-scientific. It is up to the science to put hypotheses and theories, provided that it has its disposal the well-grounded facts. But it is also up to the science to shake the hypotheses and to put them to a critical analysis, as the new facts that may be used as necessary arguments become available. The science cannot base its activity upon the faith in infallibility of scientificial authorities. A scientific discussion which admits the facts, the observed phenomena and their logical interpretation is the only basis for any scientificial activity. The scientists who forget this truism are at the same time dooming the domain of science represented by them to decrepitude. I am referring in my article to the papers of Koppen, Wegener, Gams, Bryan, Pflug, Schwarzbach. These papers cannot be ignored, as they faithfully represent the stated facts which every scientist must take under consideration. The diluvial theory of Penck and Bruckner cannot stand in its present form, because of the contradictions it contains. Changes which must be introduced into this hypothesis are justified by numerous and new conquests of the science. In such a situation every conception which brings some new elements into the diluvial theory of Penck and Bruckner ought to be discussed in a scientific way. If an argument of this new conception is fallacious and not acceptable, the error must be distinctly pointed out. The same critera must be applied if the value of the new hypotheses is to be estimated, and only such a discussion may bring positive result.
Stratigraphical notes on the standard sequence of the Upper Gondwanas of India
Authors: Sah S.C.D.
Published: September 2022

Recent additions to the knowledge of the geological history and the floral characters of the various Gondwana members in India necessitate to revise the so far accepted standard sequence of the Upper Gondwana formations. A new scheme based on the geological history and the palaeobotanical characters of the beds is here proposed. The sequence is represented by Mahadeva and Jabalpur series (in the revised sense). The former consists of two stages - Pachmarhi and Denwa, while the latter consists of four floristic zones corresponding to: Parsora, Rajmahal, Nipania and Bhuj.
Revision of the genus Gondwanoxylon Saksena with critical remarks on the fossil woods of Ailanthoxylon Prakash

Published: September 2022

The two fossil dicotyledonous woods, Gondwanoxylon kathotiai (Saksena, 1963) and G. ghiarii (Saksena, l.c.). have been re-investigated here from their type slides. On re-description they have been found to resemble the genus Ailanthus of the family Simaroubaceae, and therefore referred to the genus Ailanthoxylon Prakash (1959). The species, Gondwanoxylon kathotiense, is found to be identical to the already described Ailanthoxylon indicum Prakash whereas G. ghiarense, an entirely new species of Ailanthoxylon, is re-described under the revised name Ailanthoxylon ghiarense (Saksena) comb. nov. In the later part is given a critical review of the hitherto described species of the genus Ailanthoxylon. Because of no essential differences the species A. scantiporosum Ramanujam (1960). A. mahurzariense Shallom (1961) and A. pondicherriense Navale (1964) have been united here under the name Ailanthoxylon indicum Prakash (1959), which has priority over the rest.

Sporological Correlations of Coal Seams in Saunda and Gidi Areas of South Karanpura Coalfield, Bihar, India
Authors: Bhardwaj D.C. , Tiwari R.S.
Published: September 2022

Sixty-seven coal samples out of six bore-holes in the Saunda and Gidi areas of South Karanpura Coalfield, Bihar, have been palynologically investigated. The various forms of dispersed spores and pollen grains are assigned to forty-three genera. On the basis of generic percentage frequency and their distribution, nine miospore genera have been considered representing the dominant association. They are Leiotriletes, Lopltotriletes, Horriditriletes, Microbaculispora, Cyclobaculisporites, Striatopodocarpites, Faunipollenites, Vesicaspora and Sulcatisporites. Along with them two rare genera Indotriradites and Dentatispora are also included due to their characteristic distribution. On the basis of qualitative and quantitative miofloristic values, the samples fall in to 3 major coal seams out of which one is met with only in two boreholes representing the youngest deposition, second is represented in all the bore-holes, and the seam occupying the position of oldest deposition is struck in five of the six bore-holes and is variously split. Apart from this, there are two samples which stand apart and are supposed to be of local importance.

Palynology of the Mesozoic sediments of Kutch, W. India. 7. Reworked Permian pollen from the Upper Jurassic sediments - a discussion
Authors: Venkatachala B.S.
Published: September 2022

Recycled Permian pollen are recognized in Katrol (Upper Jurassic) sediments along with typical Jurassic spores and pollen. Similar records in Jabalpur Series near Sehora (DEV, 1959) and Cannanore lignites (POTONIE & SAH,1958) are also considered as significant in picturing the depositional history. It is inferred that Permian sediments extended as far as Kutch in the west and Cannanore in the south and have been since eroded away and redeposited in later times.

On the occurrence of two new fossil woods belonging to the family Lecythidaceae in the Tertiary rocks of South India
Authors: Awasthi N.
Published: September 2022

Palynological fossils from 9 exposures representing Katrol (Upper Jurassic) and 5 representing Bhuj (Lower Cretaceous) sediments in Kutch are studied. The dispersed spores and pollen are referred to 65 genera and 161 species besides hystrichosphaerids, dinoflagellates and microforaminfera. It is observed that on the basis of presence or absence of spore-pollen genera Uprer Bhuj sediments (viz. Walkamata and Dayapar sections) can be distinguished from the Katrol sediments; but the fossils of Lower Bhuj sediments (viz. sediments from Trombau and Pat river sections) are closely comparable to those occurring in Katrol sediments. The Katrol sediments can, however, be distinguished from the Lower Bhuj sediments on the basis of 11 restricted species. Three palynological zones established here point out the gradual change of flora during the Upper Jurassic and Lower Cretaceous times in Kutch.

Sporological Correlation of coal Seams in some blocks of Sohagpur Coalfield, M.P. India
Authors: Bharadwaj D.C. , Srivastava S.C.
Published: September 2022

The present paper includes a sporological study of 53 bore hole coal samples from Bhaskarpara, Kutkona and Batura blocks of Sohagpur Coalfield, M.P., India. The distribution of various palyno-taxa among the samples has suggested the occurrence of eight coal seams distinguished by eight spore assemblages. Miospore Assemblage G is characterized by the dominance of Brevitriletes and   Sulcatisporites. The Assemblage F shows a dominance of Brevitriletes closely associated with Microbaculispora and Indotriradites. The last genus becomes dominant in Assemblage E1 with the former two as subdominants. In Assemblage E, the subdominants are Hennellysporites and Illinites. Brevitriletes again ranks highest in Assemblage D and is associated with subdominant Sulcatisporites. In Assemblage C, Brevitriletes continues to be dominant but the association is marked by the subdominance of Horriditriletes and Sulcatisporites while in Assemblage B Horriditriletes becomes the most dominant genus and remains associated with Brevitriletes and Sulcatisporites. Assemblage A is characterized by the dominance of Sulcatisporites in association with Striatopodocarpites and Striatites.

The sporological succession is marked by three miofloral changes segregating four groups of assemblages. Chronostratigraphically, Assemblage G belongs to Lower Karharbari Stage, Assemblages F-E represent Lower Barakar Stage, Assemblages D-B represent Middle Barakar Stage and Assemblage A represents the Upper Barakar Stage.

On the Microscopic nature of coals from Majri Area, Wardha Valley Coalfield, Maharashtra
Authors: Pareek H.S. , Pande B.C.
Published: September 2022

The microscopic nature and composition of the Coals from Majri (20º 8': 79º 2') area, Wardha Valley coalfield, Maharashtra, about which no data whatsoever exists, are presented in this paper. These are microfragmental coals, comprising inertinite, vitrinite and exinite (sporinite), in decreasing order of abundance, occurring as mainly durite, fusite, "intermediates ", clarite and vitrite. The mineral and shaly matter is quite common and thoroughly intermixed with the organic layers, which alternate or are interbedded with shale and carbonaceous shale bands.

The Wardha valley coalfield is separated to its south-east from the adjacent Godavari valley coalfield by the Upper Gondwanas. The coal bearing formations of these coalfields may thus continue below this cover. A large spread of the Gondwana sediments, whereby these coalfields form only a part of the Wardha-Godavari valley basin, is thus suggested. The petrological studies of the Majri, and Tandur (Godavari valley coalfield) coals have indicated close proximity, then with the coals of the other basins. There is, however, a lateral variation in the composition of coal, and that appears to be related to the source of sediments, conditions of deposition and the vegetal transformation.

The origin of Shola Forest in the Nilgiris, South India
Authors: Vishnu-Mittre  , Gupta H.P.
Published: September 2022

The formation of Shola forest, the closed evergreen woods in the vicinity of Ootacamund in the Nilgiris in south India, commenced about 35,000 years ago through gradual invasion of the grasslands under a regime of low precipitation, absence of frost and high speed winds. The present disjunct distribution of the Shola forest is due to destruction of the forest probably by Man and much of the grasslands today seem due to anthropogenous activity.

Some new Miospore genera from Upper Gondwana coals of India
Authors: Singh H.P. , Kumar Pramod
Published: September 2022

Seven new miospore genera have been described from the Upper Gondwana Coals of the Jabalpur Stage, Jabalpur Series, represented in the Satpura Coal Basin, Madhya Pradesh, India. Among these, 5 genera are trilete viz., Haradisporites gen. nov., Coniatisporites gen. nov., Biformaesporites gen. nov., Lametatriletes gen. nov., Venusteaesporites gen. nov., and 2 are monolete, viz., Metamonoletes gen. nov., and Dettmannites gen. nov. Haradisporites is characterised by having small, triangular miospores with characteristically sinuous Y-rays near the apex. Coniatisporites possesses exine sculptured with coni, grana or small bacula in varying proportions. Biformaesporites incorporates circular to subcircular, trilete miospores having exine sculptured with bacula, coni and spines. Lametatriletes is characterised by having variably thickened exine, more at the angles, sparsely punctate ornamentation, puncta prominently distributed in several linear rows along the y-rays. Venusteaesporites has got two layered exine, outer punctate all over but for the region of angles, inner structureless as well as thicker at the angles. Metamonoletes is characterised by having ornamented exine with coni and verrucae, the latter elements being rare. Dettmannites is a monolete form and has verrucose exine. Verrucae are small and low around the monolete mark. Distal polar area has fainter ornamentation of the exine, grading into thicker exine and bigger verrucae towards the periphery.
AN OVERVIEW OF PATTERN RECOGNITION
Authors: C V Haritha
Published: September 2022

The operation and design of systems that can recognize a pattern in data are the subjects of the Al research field of pattern recognition. Pattern recognition has a wide range of practical uses. These consist of fraud detection, fraud prevention, handwriting recognition, facial recognition, etc. Face recognition uses a person's face to unlock a device rather than a keyboard to enter a password. As a result, there are fewer chances that the passwords will be forgotten or leaked to an unauthorized person. Since their faces are unlikely to resemble the original user's saved face model, this also prohibits other people from using the computer. The usage of handwriting in Al is handwriting recognition, one of the most promising ways to interface with small portable computing devices like personal digital assistants. They suggested visualizing the writing process on regular paper and automatically recovering the pen trajectory from numerical tablet sequences to make this communication technique appear more natural.

Authors: Álvarez Barrientos Joaquín , Oleza Joan
Published: September 2022

En este artículo necrológico se rinde homenaje a la figura de Rinaldo Froldi, que falleció en 2011 en Italia. Este hispanista (Milán, 1924) fue catedrático en la Universidad de Bolonia desde 1968 a 1997, profesor emérito en 1998, y una de las figuras más prestigiosas del hispanismo italiano. Fue un estudioso de la literatura y cultura españolas. Entre sus estudios sobre el teatro español de los siglos XVI y XVII destaca un libro que se publicó primero en italiano, Il teatro valenzano e l’origine della commedia barocca (1961) y después en español, con distinto título y texto renovado: Lope de Vega y la formación de la comedia (1968).
Benito Varela Jácome (1919-2010)
Authors: Fernández Teodosio
Published: September 2022

El artículo presenta homenaje a Benito Varela Jácome, que murió en Santiago de Compostela el 22 de octubre de 2010. Fue un estudioso de doña Emilia Pardo Bazán y editor de escritores españoles que los programas de Literatura Hispánica exigían abordar, pero sobre todo un gran conocedor de las literatura europea y norteamericana que demostraba su obra Renovación de la novela en el siglo XX. Los trabajos de don Benito mostraban la eficacia con que él se aplicaba al análisis minucioso de las técnicas o los procedimientos narrativos, de las perspectivas adoptadas por el narrador, de los niveles espaciales y sociales representados.
Menéndez Pelayo y la cuestión de lo prehispánico en la literatura hispanoamericana
Authors: Rovira José Carlos
Published: September 2022

En este artículo se presenta la figura de Menéndez Pelayo como referente en gran parte del ámbito cultural hispanoamericano. El texto contiene cuatro apartados: Aprendemos de sus hostilidades: el caso del Inca Garcilaso de la Vega; El desprecio del mundo indígena, Ejemplos de algunas lecturas americanas y Horacio contra Nezahualcóyotl. No obstante, los prejuicios de Pelayo le llevaron a devaluar la figura del poeta Inca Garcilaso de la Vega Al Inca Garcilaso. Lo consideraba por un lado excepcional, matizando su valoración para desplazarla hacia lo extraño y hasta lo extravagante. Asimismo, trató de excluir la tradición nacional americana y la pervivencia de la tradición indígena en la literatura. Por otra parte, amplió considerablemente el nivel de conocimiento sobre la literatura hispanoamericana, aunque la intentó seguir convirtiendo solo en una prolongación de la literatura española.
Menéndez Pelayo y Manzoni
Authors: Ribao Pereira Montserrat
Published: September 2022

En este artículo, se expone el estudio que hizo Menéndez Pelayo acerca del escritor italiano Manzoni. El erudito cántabro tiene un gran interés por esta figura y su obra. Del trabajo de Manzoni, destaca: los inicios poéticos del lombardo, la importancia de los Himnos sacros y la perfección de Pentecostés y La Pasión. Aparte de las consideraciones estéticas y genéricas, Menéndez Pelayo también rastrea similitudes entre autores decimonónicos hispanos y el lombardo para profundizar en sus estudios. Pelayo estudió a Manzoni como poeta lírico, como autor dramático, como  novelista y como crítico, por lo que defiende y avala la pertinencia de Manzoni en el horizonte estético del siglo XIX.

Lope de Vega en el Romanticismo español
Authors: Rubio Cremades Enrique
Published: September 2022

La figura de Lope de Vega fue analizada con precisión en la primera mitad del siglo XIX. Románticos y neoclásicos debatieron con especial atención el corpus literario de Lope, especialmente el referido a la dramaturgia. La preceptiva neoclásica y la estética romántica se enfrentaron entre sí tanto en los círculos literarios de la época como en las publicaciones periódicas del momento. Desde esta perspectiva analizamos la dramaturgia de Lope de Vega, desde su recepción en la escena española hasta su rechazo o imitación.
