Proposed conservation assessment
Widespread and often extremely common species, with an EOO of> 10 000 000 km 2 and found in numerous protected areas. We assess B. glabra as Least Concern (LC).
Synonymy notes
Previous authors have treated the name B. populifolia Schott as a later homonym on account of the earlier publication of B. populifolia Kunth (Humboldt et al. 1825: 185). However, in the protologue of B. populifolia Schott, the author states the name “est. B. scandens Sw. ”, implying he knew this was the same species as B. scandens (now a synonym of B. glabra). The name B. populifolia Schott is therefore an invalid, rejected name rather than an illegitimate later homonym.
Typification notes
Begonia scandens is a superfluous name because the author cited the earlier name B. glabra in synonymy (Swartz 1788: 86). No type was cited under the protologue of B. scandens so, the type of B. scandens is the same as the type of B. glabra (Turland et al. 2018: Article 7.5).
The protologue of B. locellata A.DC. cited the collection Jurgensen 958 but no herbarium was cited (de Candolle 1859: 137) so a lectotype is required. A duplicate of this collection in Kew herbarium (K000536562) has a determination slip by Alphonse Pyramus de Candolle and is an excellent specimen so we designate it as the lectotype.
Begonia elliptica Kunth was described based upon material collected by Humboldt and Bonpland close to Jaen in the Cajamarca Region of Peru (Humboldt et al. 1825: 180). There are two sheets matching this description in Paris herbarium and we designate one of these (P00679512) as the lectotype as it is the more complete specimen.
The protologue of B. lucida Otto & A.Dietr. does not cite a type collection so a lectotype or neotype is likely needed (Otto & Dietrich 1848: 162). We have not been able to conduct a full search of the principal herbaria of either Otto (LB or S) or Dietrich (HBP) to search for original material, so refrain from designating a neotype.
The name B. physalifolia Liebm. was published on the basis of material collected in Costa Rica by C. Ørsted near Naranjo at an elevation of 5000 feet (Liebmann 1852: 19). A specimen in Cophenhagen herbarium of C. Ørsted s.n. (C10008256) is an excellent match for this description so we designate it as the lectotype.
Wageneria deflexa Klotzsch was described based upon material grown in Berlin botanic gardens and the collection H. Wagener 2543 held in the garden’s herbarium (Klotzsch 1855: 233). We have not visited this herbarium and located this specimen but cite it as a holotype. It may be that there are multiple sheets of this collection in Berlin, so one may need designating as a lectotype.
Klotzsch described Wageneria montana Klotzsch based upon material collected by Ruiz and Pavón in the now abandoned village of Muña in Huánuco Region (Klotzsch 1855: 235). No herbarium was cited, so a lectotype is required. We have seen two specimens of B. glabra collected by Ruiz and Pavón: one in Oxford University herbarium and the second in Madrid. The labels of neither of these specimens indicate that they were collected in Muña so they cannot be considered syntypes. We have not carried out an exhaustive search of European herbaria for matching specimens so refrain from designating a type for this name.
Begonia scandens var. amplifolia A.DC. was described from three sheets collected by Poeppig in Peru (de Candolle 1864: 362). These were E.F. Poeppig 1928 and 1063 collected in Pampayaco and held in the Boissier herbarium, and E.F. Poeppig 1928 collected in Tocache and held in Vienna herbarium (de Candolle 1864: 362). We have seen no duplicates of E.F. Poeppig 1928 there are several sheets of E.F. Poeppig 1063 held in Vienna and Berlin herbaria. These sheets however show material of B. glauca and B. cyathophora, rather than a variety of B. glabra. Most of Poeppig’s Peruvian Begonia collections are mixed collections so it seems likely that the same is true of E.F. Poeppig 1063. We treat B. scandens var. amplifolia as a synonym of B. glabra but refrain from designating a type until the cited syntypes have been seen.
The protologue of B. hoegeana Regel & Schmidt cites material collected by C.T. Hoege in Jalapa Department, Guatemala (von Regel & Schmidt 1886: 398). Hoege was primarily a herpetologist but also collected plant specimens. We have not seen any matches that matches this description but have by no means carried out a thorough search of all likely herbaria. We do not designate a type for this name.
Begonia repens Sessé & Moç. was described based upon material collected by Sessé and Moçino in Mexico (Sessé & Moçino 1894: 219). We lectotypify this name based upon a sheet of M. Sessé & J.M. Moçino 4512 held in MA herbarium (MA603076) that matches the description and is labelled as “ Begonia repens ”.
The name B. glabra var. coralipetiolaris Anon. was described without a type (Anonymous 1946: 153), as types were not a requirement until 1958, this does not invalidate the name. We know of no material that could be considered original material and refrain from designating a type.
Identification notes
Begonia glabra is by far the most common climbing Begonia in Peru and is abundant in humid forests. Together with B. rossmanniae, it is one of two species of climbing Peruvian Begonia with basifixed leaves that are three-veined from the base. It is readily distinguished by its persistent (vs deciduous) stipules and axillary, symmetrical inflorescences (vs asymmetrical and terminal inflorescences).
Species unplaced to section
There are six species of Begonia from Peru that do not fit into the sectional classification provided by Moonlight et al. (2018). Four of these six species were included in the phylogeny provided by Moonlight et al. (1018) but the authors took a cautious approach to redefining the limits of existing sections or describing new sections. Changes were only made where enough species in sections and their relatives were sampled, where phylogenetic relationships were well supported, and where clades were supported by morphology. All Peruvian species that were left unplaced to section fall within the broad definition of B. sect. Knesebeckia provided by Doorenbos et al. (1998), but this section is highly polyphyletic so many recently described species have been left unplaced to section (Moonlight et al. 2018).
