26 LESQUEREUX — CATALOGUE 
175. A. palustre, Schweer. 
Hab. swamps near Mendocino, Bol. ; Cascade Mts., Lyall. 
BARTRAMIA, Hedw. 
176. B. stricta, Brid. 
Hab. on rocks and ground near San Francisco, Gol. 
It differs from the European form only by its pedicel, which is round and not 
square, obtuse under the capsule ; agreeing, therefore, with Bridel’s description, which 
does not mention this peculiarity. 
177. B. thyphylla, Brid. 
Hab. foot of Mt. Dana, ditches, abundant, Bo/. It is the Alpine form, in 
compact tufts, with short stems and pedicels ; also Cascade Mts., Lyall. 
178. B. fontana, Brid. 
Hab. Yosemite Valley, Big Trees; Clear Lake, on wet rocks, Bol., Brew. 
Appears common in the Sierra Nevada Mts.; Fort Colville, Lyall. 
179. B. Menziesii, Turn. 
Hab. on shaded rocks ; very common in California, and gathered by all the 
botanists who have explored that country, Menzies, Big., Brew., Bol., 
Bauer, ete. 
Var. foliis latioribus, brevius acuminatis, capsula longiore, ovato-elongata, ore 
Ja iori nudo, vel membrana integra circumdato. 
Hab. on rocks, Bol. 
With the normal form, whose capsule is oval, sometimes nearly round, Dr. 
Hampe has made a new species, under the name of Glyphocarpa Baueri. But the eap- 
sules of this normal form have generally a well developed peristome, though, indeed, 
this peristome is sometimes replaced by a pellucid membrane, lacerated in the form 
of irregular teeth, or even is totally wanting. The moss, which I consider as a variety 
as described above, has generally a naked mouth, though sometimes it shows traces of 
even a well formed peristome. 
TIMMIA, Hedw. 
180. T. megapolitana, Hedw. 
Hab. Vancouver Island, Lyall. 
POLYTRICHACE AS. 
ATRICHUM, Tal. Beauv. 
181. A. undulatum, Tal. Beauv.
