Nomenclatural and taxonomic notes: — Rhynchosia minima was first described by Linnaeus (1753) as Dolichos minimus. It is the only species of the genus that has a cosmopolitan distribution. Since it has been collected in many parts of the world and studied by several taxonomists, different names have been attributed to it.
In the protologue of Glycine lamarckii, Kunth (1823) mentioned the collection “Crecit locis umbrosis, prope Havanam” but did not designate a specific type specimen. Grear (1978) in his revision of the neotropical species of Rhynchosia only cited the collection Bonpland 1328 (which possesses characters that match those given in the species protologue), deposited in P, as an isotype and no other reference to the type collection has been published since then. We designate here the specimen with barcode number P 00660115 as the lectotype of G. lamarckii.
Grear (1978) mentioned that the type species of R. punctata is housed in G, but we were unable to find it. We decided to keep this taxon as a synonym of R. minima based on an analysis of the illustration provided in the species protologue. Also, efforts to access the type species of Glycine littoralis, R. ervoidea and Phaseolus caribaeus were unsuccessful, since the original descriptions did not cite any material, and no reference to these names was observed on any specimens studied by us. Therefore, we also retained these taxa as synonyms of R. minima based on the characters that were given in the taxon protologues.
In the protologue of R. laxiflora no mention of a type specimen was made and no specimen matching the information given in the original description was found. We designate here the illustration Pl. 54 in Voyage dans l’Inde v. 44 (1841) as the lectotype of R. laxiflora.
Grear (1978) cited the collections Andersson 379 and 380 at S as the holotypes of R. aureoguttata and R. exigua, respectively. In Flora of Ecuador, Ståhl et al. (2016) correctly stated that Grear’s (1978) reference to these collection numbers was incorrect, since the numbers “379” and “380” are, in fact, the sequence of numbers used in the nomenclatural headings in the original description of these taxa. Thus, Ståhl et al. (2016) designated the collections deposited in S R. aureoguttata and R. exigua lectotypes. This procedure was justified on the grounds that there are duplicates of both collections which were probably available to Andersson when he described his two new species and no specific duplicates were designated as types by him. However, as Grear was the first who cited the collections from S as the holotypes of R. aureoguttata and R. exigua, he inadvertently lectotypified them (see Turland et al., 2018, Art. 9.10, Ex. 11; Prado et al. 2020).
Eggers (1879) described R. minima var. lutea but did not cite a specific specimen as a type. Grear (1978) cited a specimen deposited in C, annotated by Eggers as R. minima var. lutea, as a “presumed isotype ”. Nonetheless, there are three duplicates of this collection housed at C (C 10012337, C 10012338, C 10012339), and no other specimens of this collection were encountered by us. Thus, we have chosen here the specimen with barcode number C 10012337 as the lectotype of R. minima var. lutea.
Kuntze (1891) in the protologue of R. minima var. pauciflora mentioned the location “Portorico: Guayama” but he did not give any other information about the type specimen. Grear (1978) cited a specimen from NY as the holotype (based on the reported locality). As there is a duplicate of this collection deposited in US and the author did not specify a particular specimen as type, Grear’s (1978) citation of the specimen at NY as the holotype constitutes and inadvertent lectotypification (see Turland et al., 2018, Art. 9.10, Ex. 11; Prado et al. 2020).
Walraven (1970) mentioned that the holotype of R. minima var. diminifolia is deposited in GA, but our efforts to access it were unsuccessful. As Walraven gave a complete description of the taxon in his species protologue and all the described characters match those of typical R. minima, we retain R. minima var. diminifolia as a synonym.
Rhynchosia minima is commonly confused with R. edulis because they have similar characters regarding leaves and flowers (Fig. 10 K, N), but they are quite different concerning fruit shape (falcate in R. minima [Fig. 10 L–M] vs. oblong to slightly-obovate in R. edulis). Other characters that differentiate these species are discussed in the taxonomic notes of R. edulis.
Reproductive phenology: —Flowering and fruiting throughout the year.
Distribution and habitat: — Rhynchosia minima has a cosmopolitan distribution. It is widespread throughout South America, except for a lack of records from Uruguay (Fig. 12). It grows in a wide variety of environments, including ruderal areas, pastures, roadsides, forest edges, grasslands and campos rupestres (rocky fields).
Conservation status: —Least Concern (LC). Rhynchosia minima is assessed as LC based on IUCN Red List criteria (Poveda 2012; IUCN 2022). The species is the most widespread of the genus and the only one which has a cosmopolitan distribution.
