Rediscovery of Senecio australis Willd. (Asteraceae) after nearly two centuries
Authors: Belcher Robert O. 
Published: April 2006

SummaryBelcher, R. O.: Rediscovery of Senecio australis Willd. (Asteraceae) after nearly two centuries. ‐ Taxon 41: 235–252. 1992. ‐ ISSN 0040‐0262.Senecio australis Willd. is based on a Forster specimen said to be from New Zealand but has never again been collected there. Willdenow's name was misapplied by Sprengel to a taxon of the S. linearifolius complex of Australia, a usage rejected by Willis (1957). Hooker and Bentham both supposed S. australis to be some part of S. lautus G. Forster ex Willd. The question has remained controversial. It is here demonstrated that specimens collected on Norfolk Island and adjacent islets are identical with the holotype of S. australis, and are specifically distinct from the holotype of S. lautus. These two species are readily distinguished by consistent significant differences in calycular bracteoles, numbers of ray florets, and other features.
Bessey and Engler: a numerical analysis of their classification of the flowering plants

Published: April 2006

SummaryCuerrier, A., Barabé, D. & Brouillet, L.: Bessey and Engler: a numerical analysis of their classification of the flowering plants. ‐ Taxon 41: 667‐684. 1992. ‐ ISSN 0040‐0262.The classifications of Bessey and Engler were compared using the Mantel and Lapointe‐Legendre consensus tests. Even if real differences were noted in some of the dicta or principles underlying their systems, content of groups at the ordinal level was not statistically different. The main difference lies more in the hierarchical, topological structure of their classifications. Bessey's classification is less polytomous in the higher categories than Engler's. We hypothesize that Bessey was more concerned with the higher level, using a divisive approach to construct his classification, and Engler with the lower level, using an agglomerative or mixed approach. Our results show that Bessey's classification does not fully represent ‘an expression of a theory of evolution‘. Engler and Bessey appear to have used sequences of taxa to reflect their morphological progressions. The results of the numerical and historical analyses were in agreement. The former helped refining the results of the latter.Il faut commencer une étude par quelques propositions évidentes qui fixent les idées. Cela fait, en général, un travail ennuyeux; mais nous avons une grande chance: c'est que les évidences, dont il s'agit ici, ont été négligées.Jean Paulhan (1948)
Species limits and hypotheses of hybridization of Solanum berthaultii Hawkes and S. tarijense Hawkes: morphological data
Authors: Spooner David M. , van den Berg Ronald G. 
Published: April 2006

SummarySpooner, D. M. & Berg, R. G. van den: Species limits and hypotheses of hybridization of Solanum berthaultii Hawkes and S. tarijense Hawkes: morphological data. ‐ Taxon 41: 685‐700. 1992. ‐ ISSN 0040‐0262.Solanum berthaultii Hawkes and S. tarijense Hawkes have been recognized as distinct species by all authors since their description in 1944. Some authors have considered them as sister species, but more recently they have been treated as unrelated species belonging to separate superseries. Hypotheses of species boundaries and hybridization have been examined using principal components analysis, stepwise discriminant analysis, canonical discriminant analysis, and one‐way analysis of variance. 25 morphological characters measured on four individuals from each of 84 living accessions from throughout their natural range were analysed. Extensive intra‐accession, intraspecific, and interspecific variability have been found in many characters, including those previously given great taxonomic weight. 9 characters show no statistically significant differences between species or putative interspecific hybrids. The remaining 16 characters show statistically significant differences between species and putative hybrids, but show so much variability that repeatable identifications of some accessions would require the use of population samples. The data suggest the possibility that the two species should be treated as one. Other currently‐recognized species within S. sect. Petota may need to be reevaluated for synonymy. The results also question the hypotheses of extensive hybridization, interpretation of series designations, and the phylogenetic interpretation of corolla shape at the superseries level in S. sect. Petota.

The concept of “potential taxa” in databases
Authors: Berendsohn Walter G. 
Published: April 2006

SummaryBerendsohn, W. G.: The concept of “potential taxa” in databases. – Taxon 44: 207‐212. 1995. – ISSN 0040‐0262.The concept of a “potential taxon” as a name‐ and literature‐related data area in botanical databases is introduced. A potential taxon is a name with taxon circumscription information attached to it by means of one or more literature references. As a compromise solution between linking information in database systems entirely to specimen data or only to accepted names, using potential taxa can effectively preserve information links without hindering rapid database input and information processing. It is suggested that a potential taxon be cited by its name, followed by the abbreviation “sec.” (for secundum = according to) and at least one of the literature references used to define it.

Nuclear staining in algal herbarium material: a reappraisal of the holotype of Callithamnion decompositum J. Agardh (Rhodophyta)

Published: April 2006

SummaryMaggs, C. A. & L'Hardy‐Halos, M.‐T.: Nuclear staining in algal herbarium material: a reappraisal of the holotype of Callithamnion decompositum J. Agardh (Rhodophyta). – Taxon 42: 521–530. 1993. – ISSN 0040‐0262.The taxonomic importance of uninucleate vs. multinucleate vegetative cells in the Ceramiaceae is emphasized. It has been possible to make visible nuclei in old material, including type specimens, using aceto‐carmine and aceto‐iron‐haematoxylin stains. The holotypes of Ceramium roseum and Callithamnion fasciculatum (currently known as Callithamnion roseum and Pleonosporium borreri var. fasciculatum) have uninucleate cells and belong to Aglaothamnion. In contrast, the holotype of Callithamnion decompositum, a name that has been applied to collections of at least two uninucleate taxa, has multinucleate cells; its morphological and cytological details agree with those of specimens collected in France and Ireland that were previously thought to represent an undescribed species. Female reproductive morphology (described from a thallus with gametangia in addition to tetrasporangia), in conjunction with habit and vegetative features, indicates that this species belongs to Compsothamnion (Compsothamnieae), as a third species, being distinguished from C. thuyoides and C. gracillimum by its sessile, lateral tetrasporangia. The required new combinations under Aglaothamnion and Compsothamnion are made.

Generic relationships in the Alooideae (Asphodelaceae)

Published: April 2006

SummarySmith, G. F. & Van Wyk, B‐E.: Generic relationships in the Alooideae (Asphodelaceae). ‐ Taxon 40: 557–581. 1991. ‐ ISSN 0040‐0262.Within the Asphodelaceae the subfamily Alooideae is a natural (monophyletic) group. All the genera in this subfamily are therefore considered to have evolved from a common ancestor, based on the possession of character states which distinguish this complex from all other genera of the Asphodelaceae. However, no comprehensive interpretation of phylogenetic relationships within the entire subfamily based on comparative morphological data and phytogeographical considerations has yet been accomplished. The present paper investigates phylogenetic relationships of the genera Aloe, Astroloba, Chortolirion, Gasteria, Haworthia, Lomatophyllum and Poellnitzia using cladistic methodology. The most obvious similarities amongst these genera are the succulent leaf consistency, crescentiform or cymbiform leaf outline in cross‐section and the markedly bimodal karyotype of 2n = 14 chromosomes. For the cladistic analysis 16 characters were used and the genus Kniphofia was selected as outgroup on the basis of two synapomorphies with Alooideae, namely tubular flowers and fused perianth segments. The characters are discussed in detail, polarized into plesiomorphic and apomorphic states and then employed in the generation of a phylogenetic hypothesis using the “Hennig86” software package.
