Obs. oe the gs key Ih ted the poi which 
B. Gaviona and B. Curuena differ from B. eee Mart., of which I 
consider ah Bi des ; hence I need not repeat my remarks here. 
T °y seem nearly allied to B. “igen Ruiz et Pavon, to ie infesta, 
Mart., to B. chetorachis, Mart., to B. setosa, Mart., o B. 
(Guileina) tenera, Karsten. rs ili ata is distin guiehed iy its 
below and short, and putamen obovate. 
B. infesta, Mart., can hardly, I think, be regarded as really dis- 
tinct from B. socialis, Mart., from which it is distinguished only by 
the stem bearing spines on the internodes as well as on the node es, by 
the vagina and inner spathe being slightly less spiny, by the pinnew 
being collected into groups, and by the petiole and midrib bein 
ser tenlg oe figured twice as long as calyx From B. Gaviona 
differs chiefly in stem (10-12 pedalis x 4 Aare $a in the nae 
being tomentose, in the pinne being in groups of 4- narrower 
than in &. Gaviona, in the spadix bearing 6-10 banahen and in the 
fruit being larger and smooth ; it resembles B. Curwena more heey. 
. setosa is well distinguished by the spadix bearin 20 
more branches, by the sessile ¢ flowers, by the calyx of the 9 Sone 
being much shorter than the corolla, by both of them being glabrous, 
by the giobular fruit, and by the lenticular endocarp. 
. chetorachis, by Martius’ Sa is very nearly allied to 
B. Gaviona and to B. Curu ena, from which it differs chiefly in the 
smaller number of pinnz (20g vel pluribus), in the spines of Lo 
inner spathe being shorter, and in the branches of the spadix bein 
more numerous (10-12); the haan are unknown, or they aig 
possibly yield other distinctions 
B. tenera, Karsten, is distinguished from both B.. Curuena and 
B. Gaviona by the spines at the petio le being white with black tips, 
by nd being broader 
tite white with black tips, c= e ¢ flower having both calyx and 
corolla tubular and sabre, hy the smaller fruit (nucis avellane 
minoris magnitudine i ine), an e cular endocarp. 4 oe
