Type Collection: N. T. Silva & U. Brazao 60878 (holotype N Y ; isotypes N Y ,
U S ) , collected near Marker BR-1 of the Comissao de Limites, Serra Pirapucu, Amazonas,
Brazil, elev 1250 m , 24 Jan 1966. "Climbing epiphyte; calyx green; corolla
The typical subspecies, known from eastern Guayana (including Suriname) has the
lower (and usually, at least in young leaves, the upper) leaf surfaces sparsely setose
with simple hairs as well as the usual sparse malpighian trichomes. The essentially
truncate calyx limb with infra-marginal external teeth, distant simple hairs on the
leaf margins, and the bluntly and shortly lobed ascending tooth of the stamen connectives
are the salient species features. The western subspecies vegetatively somewhat
resembles Adelobotrys adscendens (Sw.) Triana, which however has caudateacuminate
lobes on the dorsal appendage of the stamen connectives. Both subspecies
have very obscure unisetose external teeth on the calyx, while A. spruceana Cogn.
has rather prominent teeth projecting 1-1.5 m m beyond the calyx margin. Adelobotrys
rotundifolia Triana differs at least in the denser foliar pubescence and slightly projecting
cal5rx teeth; Haught 2548 (Villavicencio, Meta, Colombia) and/or Bang 1702
(Bolivia), with blunt and only slightly divided ascending appendages on the connective,
m a y represent this obscure species, known only from the fruiting type collection.
Steyermark 58006 (sterile) and Tate 911 (fruiting), both collections from the slopes
of Cerro Duida, Amazonas, Venezuela, are probably referable to A. monticola subsp
