the points. A curious genus, first established by Swartz, in Schrader's Journal. The British species approaches in 
habit to Bartramia fontana. It is quite an alpine plant, not growing in Switzerland at a lower elevation than 7 or 
8000 feet. With us it inhabits the summits of the highest Scotch mountains,particularly in the Breadalbane district. 
2233. Orthotrichtim. From «s|3-«?, straight, and t^<;^s?, hair, on account of the straight, not twisted 
direction of the teeth of the peristome. No genus can be more natural than this, notwithstanding some 
variations in the i)eristome of some of the species from the ordinary structure. Thus O. decipiens and anomalum 
have no ciliary processes ; and O. striatum has them of a peculiar"shape and beaded appearance. Many of the 
plants referred to this genus are common occupants of the aged trunks of trees, where they vegetate among 
the soft earth which collects in the clefts of the dead bark. O. Lyellii, which is the finest of our species, is 
only found on trees in the New Forest.
