    Leaves alternate, 3-foliolate; stipules c. 3 × 2 mm, triangular, sericeous; pulvinus cylindrical, 5 – 10 × 2 – 3 mm, tomentose; petiole 9 – 16 cm long, angular, densely tomentose; rachis 1 – 2 cm long, angular, densely tomentose; stipels absent; petiolules 5 – 10 mm long, densely tomentose (even more so than on the petiole and rachis); leaflet blades ovate, obovate or elliptic, apical leaflet 12 – 14 × 7 – 8.5 cm, lateral leaflets 11 – 14 × 7 – 9 cm, asymmetrical, all blades obtuse or rounded at base, acuminate or cuspidate at apex, with dense, erect hairs on the abaxial surface, venation eucamptodromous, secondary veins in 5 – 6 pairs per leaflet
    Inflorescences
    Inflorescence axillary, pseudo-umbelliform, pendent; peduncle 60 – 100 cm long, with short appressed hairs, these becoming denser nearer the apex; primary axis condensed, all the flowers closely inserted at the apex; bracts foliaceous, 6 – 8 × 3 – 4 cm, sericeous; pedicels 2 – 2.5 cm long, sericeous; flowers 9 – 10 cm long
    Calyx
    Calyx campanulate, with long, appressed hairs on both surfaces, 2 – 2.7 cm long; lobes 4, the adaxial lobe formed by two connate sepals, these shorter than the other lobes, 5 × 3 mm, apex obtuse, the other three lobes 10 – 14 × 2 – 4 mm, apex acute

    Stamens
    Stamens 10, diadelphous, nine of them fused for approximately 60% of the filament length, the tenth stamen free; filaments 8.5 – 9.5 cm long, glabrous; anthers ovate to oblong-elliptic, basifixed, 5 mm long
    Gynoecium

    Seeds
    Seeds 2.5 × 2 cm, round, black; the hilum black, circling c. 85% of the seed circumference
    Figures
    Fig. 2.
    Note
    Mucuna cajamarca is diagnosed by a pseudo-umbelliform inflorescence on a pendent peduncle 60 – 100 cm long; bracts 6 – 8 cm long; flowers 9 – 10 cm long, corolla yellowish-green; fruits with a dense covering of urticating hairs, transverse lamellate ornamentation on the valves and a lignified wing along the margins; circular seeds (somewhat laterally compressed) with a hilum nearly the length of the seed circumference. This species is closely related to M. cuatrecasasii, but differs by the hairs on the abaxial surface of the leaflets (appressed in M. cuatrecasasii; erect in M. cajamarca), the pod ornamentation (slightly and obscurely ornamented in M. cuatrecasasii; strongly ornamented by transverse lamellae in M. cajamarca). M. cuatrecasasii is endemic to Colombia, whereas M. cajamarca is endemic to the Cajamarca region of Peru. The epithet is based on the name of the department of Peru to which this species is endemic.
    Distribution
    Mucuna cajamarca is endemic to San Ignacio province, Cajamarca, Peru (Map 1).
    Ecology
    In primary and secondary forest; alt. 1300 – 1700 m.
    Conservation
    Mucuna cajamarca has a very restricted geographical distribution. Cajamarca department, and especially the Marañón Valley within it, is well known to be high in endemic taxa (e.g. Lewis et al. 2010) and thus deserves conservation attention. Only three specimens of M. cajamarca are known to date, suggesting that the species is not common. According to IUCN criteria (2001) this species can be temporarily assessed as Vulnerable (VU).
    Phenology
    Known to flower Nov. – Feb.; collected in fruit in March.
    Vernacular
    ojo de carnero and ojo de venado.
