Var. heaiieats (Trail hb. Palm., 58).—Under this name I 
separate from B. oligocarpa a Palm found by me near Esaltacion, on 
the Rio Madeira; it differs from the true B. oligocarpa in having 
shorter leaves (about -6™), very like those of B. Juruensis, with short 
petiole and vagina (each about -1™), both entirely unarmed. The 
inner spathe is unfortunately wanting, but the = and fruits 
agreed somites with the same parts in B. oligocar,

Sees B. incommoda, and B. tenuis; it is also very like B. 
eumorpha, from which it may be distinguished, however, by 
armature of the leafstalks. en bearing spadix and spathes, and 
still more when in flower or fruit, it is easily rec e 
absence of spines on the spathes, by ie simple spadix, by the — 
ovul fruits with oval endocarp, and by the presence a a Ss steri
