species is an easily recognized one from the yellowish or bright-green 
silky foliage, the pale-yellow seta, and the bright orange-brown capsule, 
curved or gibbous, and distinctly tapering to the mouth when well developed. 
e specific name here adopted will probably be somewhat unfamiliar, 
and it will be necessary to go at some detail into the history of the plant 
to explain the position. Hooker, in the “ Music Exotici,” described clearly 
and with some fullness, and figured very accurately on tab. exliv, a plant 
from the Cape of Good Hope, collected in 1791 by Menzies, under the name 
of Dicranum flexifolium, the peristome and calyptra having then not been 
seen. It is clearly a species of Ditrichum, and it seems unaccountable that 
C. Miller (Syn., 1, 651) should, in the absence no doubt of specimens, have 
queried it as a synonym of Weisia viridula Brid.

C. Miiller, as has been mentioned, failed to recognize the affinity of 
Hooker's species, and in consequence described the South African plant as 
new under the name of Leptotrichum capense (Syn., i
