318 RADULA. 
perpaulo minor, oblongo-globosa, ad basin usque quadrivalvis. 
Elateres preelongi torti bispiri, utrinque obtusi. Spore magne, 
elateres diametro quadruplo excedentes, globose lzeves. 
Obs. The abnormal, quadrangular and quadrifid perianths, plainly 
show that organ to originate in two bilobed leaves. Where the sutures 
are cristate, it arises from the lobes being accrete, not exactly by their , 
edges, but with the edge of the one projecting a little beyond that of the 
other as a salient wing, or crest. 
In the Rio Negro plant the leaves slightly overpass the stem at the 
antical base, in that from the Andes they barely cover it, and that is the 
only tangible difference.
