on one side. Lid awl-shaped, slanting, reddish. Veil delicate, pale.

occupying nearly their whole breadth. Muse. Brit. E.)

of rivulets in the Highlands of Scotland. Dickson. Also in Ireland,

four-cornered, the younger tendril-like: leaves pressed to, straps 
awl-shaped. Dicks, ii. 8. 
Dicks . 4. 9. a. b.—(E. Bot. 1135— Muse. Brit. x. E.) 
Full-grown shoots upright, with leaves disposed in four rows, blackish, yel¬ 
lowish, green above, sometimes sending out young shoots from the ends ; 
young shoots flexuose, like a climbing plant, reddish. Leaves of the full- 
grown shoots very closely tiled, pressed to, upright, strap-shaped, awl- 
shaped towards the end; those of the shoots minute, egg-shaped, few. 
Capsules upright, somewhat oblique, mouth contracted. Fringe with a 
ring. Dicks. (The fringe is without doubt simple. The young slender 
zigzag shoots, figured and so minutely described by Dickson, are only pro¬ 
duced when the plant is placed in a moist and somewhat warm situation, 
almost entirely secluded from light and air, neither are they peculiar to 
this species, for I have produced them in Mnium purpureum , &c. &c. 
merely by placing it in such situations as I have described; in all cases 
where these are produced, I have further remarked that they invariably 
point in that direction from whence the very small portion of light or air 
entered, as to the hinge of the botanical box when the experiment was 
made in it. Br. E.)
