Etymology
The protologue of Begonia fischeri cites “D. Ferd. Fischer in litt.” and the epithet means Fischer’s Begonia. We believe this refers to Friedrich Ernst Ludwig von Fischer.

Proposed conservation assessment
Widespread and common, both within and outside of Peru, and within disturbed areas. We assess B. fischeri as Least Concern (LC).
Typification notes
In 1820, Schrank published the name B. fischeri, citing plants growing in the warm house in Munich botanical gardens from Rio de Janeiro in Brazil (Schrank 1820: pl. 59). The protologue also included an illustration of these plants and stated that the same species had also been sent by C.F.P. von Martius. There is an excellent specimen collected by von Martius in Munich herbarium (M-0145727), which is a good match for Schrank’s description and illustration. We therefore designate this as the lectotype of B. fischeri. There is also a part of a specimen collected by von Martius in New York herbarium with a label stating it is a “Fragm. ex hb. Acad. Monac” (NY00453926). This may have been part of the lectotype collection, and we assume it was in Munich in 1820, because New York herbarium was not established until 1895. We therefore tentatively treat this sheet as an isolectotype of B. fischeri.
The protologue of B. patula Fisch. ex Hornem. cites material introduced from ‘horto Garenkano’ (Hornemann 1819: 108). Jens Wilken Hornemann, who published the name, was primarily based in Copenhagen herbarium but examined additional material at other herbaria including BM, HBG, K, KIEL, LE, P, S, and W. It is possible that there is cultivated material seen by Hornemann in any one of these herbaria that could be designated as a lectotype. We refrain from designating a neotype of B. patula before a thorough search for original material has been carried out, with a specific focus on Copenhagen herbarium.
The protologue of B. Pauciflora Lindl. consists mainly of a letter written by Lindley describing a plant that flowered at the Colville Nursery in London (Lindley 1820: t. 471). No specimens are known that match Lindley’s description, so we lectotypify this name based upon the excellent illustration in the protologue.
George Bentham described B. palustris A.Hartw. ex Benth. based upon the collection A. Hartweg 1022 and cited no herbarium (Bentham 1845: 184). There are duplicates of this collection in at least seven European herbaria, but Bentham was based at Kew, so we chose a lectotype from there. We select the sheet K000536747 as the lectotype because it has more material than the alternative sheet and has the protologue citation written upon it in what may be Bentham’s handwriting.
Klotzsch’s description of B. brasiliensis Klotzsch included a reference to the collection F. Sellow 2191 (Klotzsch 1855: 154). Jacques & Mamede (2005) stated incorrectly that there is a holotype in Berlin herbarium, but as no herbarium was cited there is no holotype. There are two collections of this collection in Berlin herbarium. We choose B100242117 as the lectotype of B. brasiliensis because it includes illustrations by Klotzsch indicating he used it to describe this taxon and because there are photographs of it in various herbaria (F neg. 20895).
Begonia elata Klotzsch was described based upon material collected by Friedrich Sellow in Brazil and no herbarium was cited (Klotzsch 1855: 155) so it is appropriate to designate a lectotype. There are five duplicates of the collection F. Sellow 135 in Berlin herbarium that all match this description and Jacques & Mamede (2005) designated a lectotype in Berlin herbarium. Unfortunately, they did not specify which of the five duplicates they intended to be the lectotype so only effected the first stage of lectotypification. We select the duplicate B100242122 as the lectotype because a photograph of this sheet is in several herbaria (F neg. 20894) so it has been treated as the de facto type since the 1940s.
Klotzsch cited the collection C. Gaudichaud-Beaupré 1068 in the protologue of B. macroptera Klotzsch but cited no herbarium (Klotzsch 1855: 154). Jacques & Mamede (2005) cited the holotype of this name as a duplicate in Paris herbarium; however, as no herbarium was cited in the protologue, no holotype exists (McNeil 2014). Jacques & Mamede’s citation does not count as an effective lectotypification, because since 1990 a lectotypification is only effective if the word “ lectotypus ” or a modern equivalent is used (Turland et al. 2018: Article 9.23). Klotzsch’s home herbarium was Berlin and a duplicate in this herbarium includes illustrations demonstrating it was used by Klotzsch to describe B. Macroptera (B100242111). We designate this sheet the lectotype of B. macroptera.
Begonia malvacea Klotzsch was described based upon material collected by Friedrich Sellow in Brazil (Klotzsch 1855: 153). Jacques & Mamede (2005) were unable to lectotypify this name because they could not find any suitable material. There are numerous sheets of B. fischeri collected by Sellow in Brazil, but we have only found one that is determined by Klotzsch as B. malvacea (B101068567). We designate this as the lectotype of B. malvacea. We also note that there is a fragment of a photograph in Kew (F neg. 20897) that supposedly shows material of B. malvacea collected by Sellow in Berlin herbarium. This also shows B. fischeri but is not the same specimen as our lectotype. We have not been able to match it to any of the online material of B. fischeri in Berlin herbarium. This may be an isolectotype of B. malvacea.
Klotzsch published the name B. moritziana Klotzsch and cited material collected by Johann Wilhelm Karl Moritz in Colonia Tovar, near Caracas in Venezuela (Klotzsch 1855: 151). There are duplicates of the collection J.W.K. Moritz 1705 in the herbaria of Berlin, the British Museum, and Kew that match Klotzsch’s description. We designate the duplicate in Berlin as the lectotype of B. moritziana because it has illustrations drawn by Klotzsch, indicating he used this sheet when describing B. moritziana. We note Jacques & Mamede (2005) cited a duplicate of a collection “ Moritz s.n. ” in Berlin as the holotype of this name. We have not seen any unnumbered specimens collected by Moritz in Berlin and as no herbarium was cited in the protologue there is no holotype.
Begonia parvifolia Klotzsch, like many of the names published by Klotzsch, was described based upon material collected by Friedrich Sellow in Brazil (Klotzsch 1855: 153). A sheet in Berlin herbarium (B100242107) is labelled with his name in Klotzsch’s handwriting. This sheet was also photographed as the type of B. parvifolia in the 1940s and the photograph distributed to several herbaria (F neg. 20900). We designate this the lectotype of B. parvifolia.
Klotzsch described B. setosa Klotzsch based upon material collected by Friedrich Sellow in Brazil (Klotzsch 1855: 151). There are several sheets of at least one collection made by Sellow and annotated by Klotzsch as B. setosa, including F. Sellow s.n. (B100247920), 4385 (B100247917, B100247918, B100247919). There are also sheets annotated as B. setosa in another hand, including F. Sellow s.n. (B100249721, B101068569). We designate the unnumbered collection annotated by Klotzsch (B100247920) as the lectotype of B. setosa. Klotzsch typically cited collection numbers where available so we rule out all duplicates of F. Sellow 4385. We also rule out all specimens that do not have Klotzsch’s handwriting.
The protologue of B. vellerea Klotzsch cites material collected in Serra de Estrella in Brazil by Friedrich Sellow (Klotzsch 1855: 152). No herbarium was cited but there is a specimen that matches this description in Berlin herbarium (B100243043). We designate this collection the lectotype.
The protologue of B. ermaniii Klotzsch cites material collected near Rio de Janeiro by Professor Erman (Klotzsch 1855: 155) and, as no herbarium is cited, there is no holotype. Jacques & Mamede (2005) incorrectly cited a holotype in Berlin herbarium but as this was after 1990, this was not an effective lectotypification (Turland et al. 2018: Article 9.23). We designate the sheet B100242115 as the lectotype of B. ermaniii and the later combinations of the basionym. This sheet was determined by Klotzsch as B. ermaniii and a photograph of the sheet is present in various herbaria (F neg. 20883), so it has previously been used as a de facto type.
Klotzsch described B. uliginosa Schott ex Klotzsch based upon material collected by H.W. Schott in Brazil (Klotzsch 1855: 155). There are two matching collections in Berlin herbarium: H.W. Schott 927 (B100242118) and 928 (B100242119). We designate the former as the lectotype of B. uliginosa because it is the most complete collection and includes illustrations suggesting it was used by Klotzsch to describe the species.
Alphonse Pyramus de Candolle described B. tovarensis var. ocanensis A.DC. (de Candolle 1864: 303) based upon material of the collection L. Schlim 100. There is a specimen of this collection in the de Candolle’s herbarium (G-DC) and we designate this the lectotype of this name. The specimen citation in the Prodromus says “in Linden” and it may be that de Candolle was attempting to cite a specimen “in h. Linden”, which is his usual way of citing Brussels herbarium. If this were the case, any specimen of this collection would supersede our lectotype (Turland et al. 2018: Article 9.3). We have however been unable to locate any specimen matching this description in Brussels herbarium so assume this is not the case.
The protologue of B. cilibracteola C.DC. cited the collection J.F. Cowell 388 but cited no herbarium (de Candolle 1919: 12) so all duplicates are syntypes. The author was based in Geneva herbarium, which includes a duplicate of this collection. This duplicate comprises a single leaf in a capsule, which is not suitable to function as a lectotype. We designate the syntype in the US National herbarium (US 00115281) as the lectotype because it has a determination slip by Anne Casimir Pyramus de Candolle. The duplicate in the New York herbarium (NY00112266) is more complete, but we cannot confirm that de Candolle saw it.
Synonymy notes
We clarify here why B. fischeri is the correct name for this taxon. Four names have been applied to this taxon and were published in 1819 and 1820: B. patula Haw. (May 1819), B. patula Fisch. ex Hornem. (1819), B. fischeri (April to May 1920), and B. pauciflora. (July 1920). We have no evidence that B. patula Haw. refers to the same taxon as our concept of B. fischeri so exclude it from our concept (see Excluded names). Begonia patula Haw. may however invalidate B. patula Fisch. ex Hornem. as a later homonym. The exact date of publication of B. patula Fisch. ex Hornem. is unknown, but if it predates May 1918, it is the earliest correct name for our concept of B. fischeri. If it was published later, it is an illegitimate later homonym. For this reason, Jacques & Mamede (2005) suggested rejecting this name if a type is found. The first name that applies to our concept and can be proven to be legitimate is therefore B. fischeri, which precedes the publication of B. pauciflora by two or three months.
In 1842, Gardner mistakenly identified one of his own collections (G. Gardner 106) as B. villosa Lindl., which is a synonym of B. hirtella. This collection in fact falls within our concept of B. fischeri. This has been recognised since 1861, when Alphonse Pyramus de Candolle cited “ Begonia villosa Lindl. ” As a synonym of B. hirtella (de Candolle 1861: 345) and “ Begonia villosa Gardn. … non Lindl.” as a synonym of B. macroptera (de Candolle 1861: 346). Jacques & Mamede (2005) however cited “ Begonia villosa Gardner ” as an illegitimate later homonym of Lindley’s name and discussed its typification. We clarify here that this is a misapplied name and not an illegitimate later homonym.
We newly synonymise B. parvifolia Klotzsch with B. fischeri. This species was synonymised with B. patula by Smith & Schubert (1950) and Irmscher (1953) suggested that B. parvifolia should be combined with B. palustris but did not formalise the change. Smith & Wasshausen (1984) transferred most of the synonyms of B. fischeri into its synonymy; however, we cannot find any evidence that B. parvifolia has been transferred into synonymy with B. fischeri. Begonia parvifolia falls within our concept of B. fischeri so we transfer it into synonymy herein.
In 1953, Edgar Irmscher attempted to publish new combinations for several Begonia species as varieties of B. fischeri (Irmscher 1953). These were B. fischeri var. palustris (A.Hartw. ex Benth.) Irmsch.; B. fischeri var. brasiliensis (Klotzsch) Irmsch.; B. fischeri var. elata (Klotzsch) Irmsch.; B. fischeri var. ermanii (Klotzsch) Irmsch.; B. fischeri var. macroptera (Klotzsch) Irmsch.; B. fischeri var. malvacea (Klotzsch) Irmsch.; B. fischeri var. moritziana (Klotzsch) Irmsch.; and B. fischeri var. pohliana (Klotzsch) A.DC. All these names are invalid because Irmscher only provided an indirect reference to the protologues of these names’ respective basionyms (Turland et al. 2018: Articles 41.5, 41.8d).
Identification notes
Begonia fischeri is a common species in disturbed and wet, open habitats in lowland and montane Peru. It is the only annual species of Begonia in Peru with deltoid leaf blades. It is almost always in flower and fruit and the ascending, triangular ovary and fruit wings are very distinctive.
Distribution and ecology
Known from Cuba, Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina, and Brazil. Within Peru, collected in Loreto, Cajamarca, Amazonas, San Martín, Pasco, and Madre de Dios Regions (Fig. 45A). Found in Amazonia, northwest Peruvian relict montane forest, and lower and middle montane forest at an elevation of 90– 2600 m a.s.l. Begonia fischeri is also rarely found in permanently wet localities in dry forests and scrubland, such as canyons, drainage ditches, and beneath waterfalls. B. fischeri is a fast-growing annual herb and unusually among Begonia species is frequently collected growing in full sunlight.
