length of limb. Seta short and pale, caps, hemispherical, greenish 

 straw-colour, when old turbinate, lid pale, long subulate, per. bright red, 

 the teeth short truncate, of only 3 — 4 rectangular articulations, smooth, 

 sometimes foraminate. Male plants in separate tufts, much smaller 

 than female, bracts ovato-lanceolate. 



Hab. — Wet shaly rocks ; sterile.

Very close to B. acuta and resembling it in areolation, but in the latter 

 the lamina narrows more gradually and runs up to the middle of leaf ; 

 the nerve is rounder and more rigid, and the tufts are generally black at 

 base. It has also been found in Madeira and the Caucasus, and with 

 fruit in the Riesengebirge, and in Corsica by Philibert, but these are only 

 I the height of British specimens. 



CAMPYLOPUS. 

 CAMPYLOPirS ATROVIRENS. 



Var. y. epilosus Bvaithw. 



Plants more slender, with softer narrower more patent leaves, the attenu- 

 ated subula without any hyaline point. 



Hab. — Dingdong moor, Penzance (Marquand 1883) ! ! Isle of Man (Holt 1881). Tyn-y- 

 groes (Holt 1882). 



Another moss of this genus from Jersey, is referred by Mr. Boswell with a 

 ? to Campylopus adustus De Not. of which we have no specimens for com- 

 parison. We have little doubt however that the Jersey plant is a form of 

 C. introflexus, with the hair-points very short or altogether wanting. 



CAMPYLOPUS SUBULATUS. 



Var. jS. elongatus Bosw. 



In wide dense pale yellowish -green tufts. Stems tall, slender i — 2 in. long, 

 radiculose at base. Leaves more distant, of thinner texture, with a more 

 elongated subula. 



Syn. — Campylopus brevifolius Var. elongatus Bosw. in Naturalist 1883, p. 28. 

 Hab.— Banks of the Wye near Builth [Boswell 1883). 



The aspect of this moss is very different from the ordinary state, and this 

 may be greatly due to the locality in which it was found, for the stems show 

 3 years growth and are full of fine sandy deposit from the river ; it is probable, 

 therefore, the elongation of the stem is due to an effort of the plant to escape 

 suffocation.
