description: 22. Rhynchosia phaseoloides (Sw.) DC., Prodr. 2: 385. 1825. (Fig. 14 A–C)
Basionym: — Glycine phaseoloides Sw., Prodr. 105. 1788. Dolicholus phaseoloides (Sw.) Kuntze, Revis. Gen. Pl. 3(3): 62. 1898. Type: JAMAICA, s.d. (fl./fr.), Swartz s.n. (Lectotype, first-step designated by Grear [1978]; second-step designated here]: S S-R-2422 [digital image!]; isolectotypes: S 10-34209 [digital image!], S 10-34210 [digital image!]). Iconography: Rodriguésia 70: 13. 2019.
Vine climbing or suffrutescent, twining, stems simple or branched, pilose to pubescent, indumentum white to light yellow, with yellow vesicular glands, but lacking bulbous-based trichomes. Stipules 1.2–6 × 1–2 mm, free, caducous, lanceolate, externally pubescent with yellow vesicular glands, but lacking bulbous-based trichomes. Leaves trifoliolate; petiole 1.2–7.7 cm long; leaf rachis 1.5–3.8 cm long; stipels absent; leaflets 2.1–9.7 × 1.9–9.5 cm, ovate, deltoid or rhombic, surface not bullate, attenuate to acuminate at apex, obtuse, truncate or rounded at base, margin entire, pilose to pubescent, with yellow vesicular glands on the abaxial surface. Inflorescences axillary, paniculate, 5.5–30 cm long, many-flowered, exceeding the length of the subtending leaf; bracts caducous; pedicels 0.5–1 mm long. Flowers 4–8 mm long excluding the pedicel; calyx 3–3.5 mm long, pubescent with yellow vesicular glands and bulbous-based trichomes, lobes lanceolate, not exceeding the corolla in length; standard petal 6–9 × 4–6 mm, obovate, emarginate to rounded at apex, pubescent, with yellow vesicular glands and bulbous-based trichomes, claw 1–2 mm long, auricle ca. 0.5 mm long; wing petals 5–8 × 1–2 mm, oblong, claw 1–2 mm long, auricle ca. 0.5 mm long; keel petals 5–8 × 1.5–3 mm, falcate, claw 1–3 mm long; stamens 6–9 mm long; ovary 2.3–3.1 mm long, pubescent, with yellow vesicular glands. Fruits 0.9–2.5 × 0.8–10 mm, greenish to brownish, strongly constricted between the seeds, ovate or oblong, pilose to pubescent, with yellow vesicular glands, but lacking bulbous-based trichomes. Seeds 4–6 × 3–5 mm, suborbicular, bicolored, black and red, areas of coloration almost equal in area.
Nomenclatural and taxonomic notes: — Grear (1978) selected a collection of Swartz from Jamaica housed in S as a lectotype of G. phaseoloides. However, there are three duplicates of this collection in the S herbarium (S S-R-2422, S 10-34210, S 10-34209), and Grear did not specify a particular specimen as lectotype. Therefore, the type designation of Grear (1978) should be treated as a first-step lectotypification and our designation of the specimen with barcode number S-R-2422 constitutes the required second-step (see Turland et al. 2018, Art. 9.17)
Grear (1978) cited R.phaseoloides var. precatoria Grisebach(1866:74) as a synonym of R. phaseoloides. Grisebach (1866) in his protologue of that taxon described it as having red seeds with black blotches and cited the collection Wright 134. When analysing Wright 134, we conclude that R. phaseoloides var. precatoria should be recognized as a synonym of R. precatoria and not R. phaseoloides, and we do not follow the decision of Grear (1978).
Rhynchosia phaseoloides is characterized by its twining stems, its flowers almost sessile (pedicel 0.5–1 mm long), fruits constricted between the seeds, greenish to brownish, and seeds bicolored red and black with areas of coloration almost equal in area (Fig. 14 A–C).
Reproductive phenology: —Flowering from February to August, October and November; fruiting throughout the year.
Distribution and habitat: — Rhynchosia phaseoloides has a wide distribution in South America and the Caribbean. In South America, it occurs in Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Paraguay, Peru, Surinam, Trinidad and Tobago and Venezuela (Fig. 13). It occurs in several environments, including pastures, along roadsides, at forest edges, in rocky and sandy fields (campos rupestres) and in disturbed areas.
Conservation status: —Least Concern (LC). Rhynchosia phaseoloides has an EOO of 20,042,871 km 2 (GeoCAT, accessed in May 2022), and is assessed as LC based on IUCN Red List criteria (IUCN 2022). It is widespread in South America. This species is used as a cultivated ornamental plant and their attractive seeds are also used for making handicrafts and jewellery.
