Sporophyte a dark brown oval capsule 0.7-0.8 mm. long, on a 
short seta 0.5-2 cm. high; spores 6-8 » in diameter, nearly 
spherical, dark brown; elaters 250 long, wider than the spores, 
bispiral. 
A very common species on rotten wood distributed from the 
mountain region of Georgia to Wisconsin and northeastward; 
also European. 
It has been distributed by Sullivant : Musc. Alleg. 242 (as 
Jungermannia curvifolia); Austin: Hep. Bor.—Am. 60; and in Hep. 
Amer. 17. Several figures exist ; of these, Hooker, Brit. Jung. pl. 
15, and Suppl. f/. z, and Ekart, Syn. Hep. Germ. pl. 8. f 59, are 
among the best; that in Smith, Eng. Bot. g/. 1304 poorly repre- 
sents the plant.

. Gametophyte a slender creeping, usually pale green leafy stem; 
leaves often wider than long, decurrent, slightly imbricate, bifid 
one third their length with an obtuse or rarely lunate sinus and 
acute connivent segments; leaf-cells mostly uniform, 36-40 # 19 
diameter: dioicous; perianth on a very short branch, linear-fusi- 
form, fleshy, formed of three layers of cells at base and two above ; 
antheridia usually near the apex of a branch. Sporophyte @ 
short-stalked, oblong-cylindric capsule enclosed at first in a fleshy 
calyptra formed of three layers of cells; spores cinnamon-colored. 
One of our most common species growing in large patches of 
decaying logs and rarely on the ground from Florida to Virginia, 
California and generally distributed over the northern portion of 
America; also European. The species was long confused with 
C. connivens ( Dicks.) both in this country and in Europe. During 
this period it was distributed under the original name of /unge?~ 
mannia connivens by Sullivant, Musc. Alleg. 246, and as Cephalo- 
sia connivens by Austin, Hep. Bor.-Am. 57. Lindberg, thinking 
that this species was the true C. connivens, gave to that species the 
name of C. multiflora. Later, Spruce, identifying the true C. com 
nivens, unfortunately gave the same name (C. multiflora) to the 
_ present species. Under this name the species was distributed by _
