chymenium seminerve, Tay]. Acidodontium seminerve, Hook. et 
Wils. Lond. Journ. Bot. vol. v. t. 16. I. 
This elegant species has perhaps more general resemblance to B. 
crudum and B. longicollum than to any others, and agrees with them 
in having the leaves gradually larger towards the tops of the stems.

Wils.— Hook. Icones Plant. Rar. vol.iv. t. 748. Brachymenium 
Jamesoni, Tayl. Lond. Journ. Bot. 1848, p. 252. Weissia Jame- 
soni, Tayl. l. c. 1847, p.330. 
A beautiful moss, which has much affinity with B. Peromnion : it is 
perfectly distinct from Leptotheca Gaudichaudii, Schw., judging from 
the figure of that species. 
41. Bryum soboliferum, Tayl. Lond. Journ. Bot. 1846. p. 51. 
42. Bryum crinitum, Mitten, MSS.; dioicum, dense cæspitosum fasci- 
culate ramosum, folis caulinis ovato-oblongis concavis nervo 
in pilum flexuosum albidum excurrente cuspidatis, perichzetialibus 
lanceolatis margine reflexo, e cellulis laxis areolatis, theca in pe- 
dunculo gracili ovato-cylindrica, operculo conico brevissimo, pe- 
ristomio B. Hornschuchiani. 
Although this species has many points of resemblance to B. Horn- 
schuchianum, it appears to be distinct in the following particulars :—the 
plants are shorter and more densely cæspitose, the leaves are wider 
and the nerve is produced into a long white hair-like point, the cap- 
sule is longer, and the perichætial leaves have the margins reflexed.
