Much confusion appears to surround this species. Schwügrichen figured 
it supposing it to be identical with Bridel's B. patens, from Magellan ; and 
Bridel then refers to Shwügrichen's figure as representing his species. 
C. Müller (Synops. i. p. 497) refers it to B. vulcanica, Brid., an allied but 
distinct species with a shortseta. Judging from the single perfect capsule 
on the present specimen, the species differs from B. patens, Brid., from Ma- 
gellan, in the absence of an internal peristome ; its leaves are also narrower 
and more nearly like those of B. papillata, Hook. f. et Wils., but they are 
not serrulate quite down to the shoulders of the vaginant portion, although 
the papillation is nearly similar.
