( Veil striated, at length tom at the edge. Lid awl-shaped. E.) Resem¬ 
bles the B. cirratum so much that they are not to be distinguished 
without maceration. That, however, is a more slender plant, has fewer 
fruit-stalks, and the capsules are paler. Dill. (The authors of Muse. 
Brit, observe: *' f this species may be easily known from other Trichos- 
toma by the greater length and narrowness of its leaves, and by their 
remarkably crisped appearance when in a dry state. The capsules are 
generally crowded, and the teeth of the peristome connected at the base 
in filiform pairs.”

Stem upright when young, afterwards declining, and sending out a few 
branches of various lengths. Leaves spear-shaped, keeled, pressed to 
when dry. Fruit-stalk straight, three-fourths of an inch in height. Cap- 
side oblong-egg-shaped. Lid a slender cone. Mouth fringed with six¬ 
teen long, hair-like teeth, divided down to the base. Veil slender, long, 
ragged at the bottom. Fruit-stalks lateral. Hedw.

T. Ericoides of authors, E. Bot. 1991, and identified in FI. Brit, with 
B. Hypnoides. Linn. Huds. With.) “ has somewhat of a pinnated appear¬ 
ance, arising from its numerous very short branches; but in the form of 
its leaves, capsule, and peristome, it perfectly accords with T. canescens.”’ 
Muse. Brit. E.) Differs from B. Hypnoides in its upright stem, its leaves 
being very slightly serrated only at the ends, and in its longer fruit-stalk.

from the number of hairs which terminate the leaves. Dill.

About an inch and a half high. Fruit-stalk lateral. Capsides upright, 
egg-cylindrical. Leaves spear-shaped, slender, keeled, hair-pointed;

Specimen from Mr. Griffith, accompanied by others of a stunted growth,

leaves. 
Var. 3. Leaves spear-awl-shaped, mid-ribbed; shoots branched.
