others with all the leaves highly and densely papillose, and - 
others in which they are all smooth but a few here and there 
slightly parillose. It is a very perplexing, but a quite distinct 
species. A. surculare Mitt. has the branch leaves scarcely toothed 
and smooth, and most of the branches meavated to a caudi- 
form apex.

Trichosteleum brachypelma appears to be a rather widely 
distributed plant; sometimes scarcely differing from T. Boschii 
except in the smooth seta; but often with more gradually tap- 
ering leaves and less papillose cells. These characters are evident 
here, but in addition the tufts are extremely compact, the 
leaves complanate and less flexuose, often very shortly and even 
widely pointed.

Quite distinct in the very white, glistening, shortly pointed 
leaves, and quite smooth cells, though otherwise in habit and 
leaf form resembling several other species, e. g., 7. singapurense 
Fleisch. It grew closely mixed up with a form of Taxithelium 
papillatum in fruit, but none of the fruit appears to belong to
