racemiformibus, pedicellis subsessilibus confertis, calyce 8-glandu- 
loso, ovario hirsuto.—British Guiana, Schomb. 2nd Col. n. 488 (773). 
Scandens videtur, ramis novellis cinereo-pubescentibus, adultis 
glabratis. Stipulas non vidi.  Petioli 2-3 lin. longi, cinereo- 
villosi. Folia 2-4 poll. longa, 1-12 poll. lata, sæpe basi complicata, 
margine subrecurva, vix coriacea sed supra nitida rete venarum 
leviter prominula, subtus pilis adpressis molliter cinereo-pubescentia, 
costa media venisque primariis paucis prominentibus, harum infe- 
riores fere a basi folii ortæ.  Panieule 1-2-pollicares, rhachi 
subsericeo-pubescente, pedicellis parce pilosis. Rami breves, op- 
positi. Umbelle (seu potius racemuli umbelliformes) ad apices 
ramorum et panicule ipse pluriflore. Bracteæ sub ramis paniculæ 
1-2 lin. long, lineari-lanceolate, sub pedunculis brevissimis 
minute, cum bracteolis similibus confertæ. Pedicelli 3 lin. longi. ` 
Calyx parce villosus, laciniis obtusis. Petala obovali-orbiculata, 
carinato-concava, subintegra, glabra. Stamina glabra. Anthere 
oblong, connectivo erassiusculo loculis breviore. Ovarium dense 
hirsutum. Styli erassiusculi, apice truncati. Fructus haud sup- 
petit, sed ovarium vix defloratum jam in alam dorsalem excrescere 
incipit, et stylus Heteropterydis nec Banisteria.
