US!), membranaceous, glabrous on both surfaces, very rarely with scattered trichomes at distal lobes, tube 0.10-0.20 cm long, funnel-shaped, lobes usually 5 (rarely 4 or 6), 0.30-0.40 cm long, obovate, with 5-6 parallel veins and few glandular trichomes distally. Anthers of male flower 0.30-0.40 cm long, oblong, filaments 0.30-0.33 cm long, adnate to the corolla tube for further 0.05-0.08 cm, pollen present, tricolporate; anthers of female flower 0.12-0.14 cm long, filaments 0.05-0.08 cm long, adnate to corolla tube for further 0.10-0.12 cm, pollen absent. Ovary of male flower subglobose, 0.14-0.20 cm long, stylodia 2, 0.10-0.12 cm long, distally setose, ovules absent; ovary of female flower globose, 0.25-0.30 cm long, style bifid, united for 0.03-0.10 cm at the base, branches 0.25-0.30 cm long, sometimes slightly unequal, stigmas 2, extensively capitate. Fruit 0.50-0.60 cm tall, 0.60-0.70 cm wide, globose, deep orange through vermillion, turning blackish brown at maturity; style accrescent, occasionally persistent; pyrene 0.40-0.43 cm tall, 0.30-0.35 cm wide, 0.20-0.25 cm deep, ovoid, abaxial surface reticulate.

). With respect to leaf shapes and sizes, it is a morphologically variable species and is intermediate between

exhibiting mature leaves size greater than 3.5 cm (and up to 6.0 cm) long in some specimens from Guadeloupe, Martinique and Puerto Rico. Molecular data indicate the distinctiveness of this new species, whose closest relative is

from adjacent Puerto Rico and the Dominican Republic. The two species can be reliably distinguished based on inflorescence morphology (many- versus few-flowered) and leaf shape (frequently circular versus predominantly obovate). Overall similarity, however, is great with
