Leaves 3-foliolate; pulvinus 10–20 × 3.0–5.0 mm; petiole 9.0– 12 cmlong; stipels absent; rachis ca. 1.0 cm long; petiolules ca. 1.0 cm long; lateral leaflets, 9.0–13 × 6.0– 8.5 cm, asymmetric at base, cuspidate at apex; apical leaflets ovate, 8.0–13 × 6.0– 8.5 cm, rounded at base, cuspidate at apex; venation eucamptodromous, secondary veins in 6 pairs per leaflet; dense, adpressed silvery hairs on abaxial surface; sparse adaxially. Inflorescence axillary, umbel-like pseudoraceme; peduncle 30–120 cmlong; bracts 4.0–12.5 × 3.0– 11 cmlong, persistent; pedicels ca. 2.0 cm long. Flowers 7.0– 11 cmlong; calyx 1.5–2.2 cmlong, 4-lobed, the adaxial lobe formed by two connate sepals, 12 × 6.0 mm, acute at apex, the other three lobes 6.0 × 2.0 mm, acute at apex; corolla reported to be white-green ( D.

Garzón 349 COL); standard broadly elliptic, 4.0–5.0 × 3.0 cm, cordate at base, rounded to retuse at apex, claw 4.0 mm long; wings oblong-elliptic, 7.0–11 × 2.0 cm, attenuate at base, round to acute at apex, the claw 8.0 mm long; keel petals oblong-elliptic, 7.0–11 × 2.0 cm, attenuate at base, acute at apex, the claw 8.0 mm long; pubescent at base of wing and keel petals. Stamen filaments 8.0– 10.4 cmlong, glabrous. Style 8.0– 11 cmlong, sericeous, except at apex; ovary 10–14 mmlong, sericeous; stigma peltate, villous. Fruits 27–30 × 4.5 cm, slightly ornamented by transverse lamellae, covered with dense hairs, acute to acuminate at base, acute at apex, lignified wings along fruit margin, up to 7-seeded. Seeds globose, 2.5–3.0 × 2.5–3.0; hilum circling 75–85% of the seed circumference, 5 mmhigh.  Taxonomic notes:—  Mucuna cuatrecasasiiis morphologically similar to  M. klitgaardiae, but it differs by the presence of adpressed hairs on the abaxial surface of leaflets, the peduncle 30–120 cmlong, and the fruits slightly ornamented by lamellae in  M. cuatrecasasii(vs. erect hairs on the abaxial surface of the leaflets, the peduncle 20–40 cmlong, and the fruits not ornamented by lamellae in  M. klitgaardiae).  Mucuna cuatrecasasiiis endemic to Colombia, whilst  M. klitgaardiaeis restricted to Ecuadorand Peru.  Mucuna cuatrecasasiialso resembles to  M. cajamarca(see comments under that species).   Phenology:—Flowering throughout the year; fruiting March to November.   Distribution and habitat:—  Mucuna cuatrecasasiiis endemic to Colombia, in the Boyacá, Cundinamarcaand SantanderDistricts ( Fig. 3). It grows in wet forest ( D. Stancik 1146COL) alt, 200–2500 m.  Conservation status:—Following the IUCN (2016)criteria,  M. cuatrecasasiiis assessed as being of Least Concern (LC). Although our data indicate that  M. cuatrecasasiihas a restricted extent of occurrence ( 3128.87 km 2, EN) and area of occupancy ( 52 km 2, EN), there is no evidence that the species habitat is severely fragmented. Furthremore, the species has been collected from more than ten different localities.  Vernacular name: —‘Ojo de buey’ (L.K. Ruiz, personal communication).  Representative specimens examined:—  COLOMBIA. Boyacá: Gachantiva, Vereda Caja, Bosque Andinoúmido,  2 November 1998(fl.),  D.
