CRYPTOGAMIA. MUSCI. Hypnum. 
1057 
inches long. Fruit-stalk two to three inches long. Griff. Leaves some¬ 
times bristle-pointed, but not always so. In the specimens of smaller 
growth the stems are nearly upright, and the bend at the base of the 
fruit-stalk is less observable. 
(Elbow-stalked Thread-moss. E.) On moist banks in the Scotch 
mountains, near Aberfeldy. On wet brows by the sides of rivulets in 
the neighbourhood of Snowdon, Mr. Griffith; who considers this plant 
as not specifically distinct from B. alpinum. (Hooker and Taylor ar¬ 
range it under B. ventricosum , which latter they consider scarcely distinct 
from B. alpinum. E.) 
B. alpi'num. Capsules egg-cylindrical: fruit-stalk axillary : shoots 
branched: leaves tiled, spear-shaped, mid-ribbed, pointed, keeled. 
(E. Bot. 1263— Muse. Brit, xxviii. E.)— Dill. 50. 64. 
Grows densely compacted; variously branched; branches^ irregular in 
length. Leaves very numerous, oblong, keeled, straight, acute ; opake, 
smooth, shining, purplish green, but in old plants dark purple below, 
dark red above. Barren branches taper at the end, those with fruit- 
stalks broader. Fruit-stalks an inch high, dark red purple, issuing from 
a large purple tubercle. Veil purplish. Dill. 
(This species is best known by its deep shining purple colour, its rigid 
stems and leaves, which latter are straight, as well when dry as when 
moist. It is difficult, nevertheless, to form a specific character that will 
separate it from some varieties of B. ventricosum. Muse. Brit. E.) 
(Red Alpine Thread-moss. On rocks in mountainous countries. E.) 
P. April—June. 
B. marginatum. Capsules egg-cylindrical: lid beaked: leaves egg- 
spear-shaped, pointed, finely toothed, bordered. Dicks, ii. 9* 
Dicks. 5. 1. a. h .— E. Bot. 1493— Muse. Brit. xxxi. E.) 
Shoots mostly simple. Leaves , teeth remote, the mid-rib and edge red and 
thick. Fruit-stalks solitary. Capsule half egg-shaped. Lid conical. 
Veil awl-shaped. Dicks. 
(Whole plant yellowish; when seen through a microscope the margin and 
nerve of the leaf appears of a deep blood colour, and the veil of a red 
hue, which renders this Moss very discernible at first sight. Muse. Brit. 
Bordered-Thread-moss. B. serratum. Schrad. E.) Mnium serratum. 
Gmel. Pastures, Scotland; (north of England and Ireland. E.) woods, 
and shady banks.

scales: Capsule, outer fringe with sixteen teeth.
