giuscule acuminata, basi in petiolum pubescentem cuneato-angustata, mem- 
branacea, utrinque pilis adpressis breviter pubescentia v. subtus glabrius- 
cula, 5—7-nervia. Inflorescentiae axillares racemiformes, villoso-pubes- 
centes, floribus paucis; bra eteae magnae foliaceae subrhomboideo - ovatae 
v. rotundatae subvelutino-villosae margine ciliatae; infima maxima ope 
nervii medii ita rhachidi adnata est, ut tota inflorescentia epiphylla esse
