Differs from the small forms of 2. capillare L. by its capsule generally 
narrower, light red in the upper part when ripe, and by the less distinct 
border of its leaves. &, torguescens Br. Eur. is a more robust plant, with the 
‘ leaves generally strongly twisted when dry, distinctly bordered, and a synoi- 
cous inflorescence. A

Missouri: Eagle Rock, on tree (B. F. Bush, 1898). 
Easily distinguished from &. capillare L. by its synoicous flowers, very 
briefly excurrent costa and shorter capsule. Differs from B. provinciale 
Philib. by its smaller leaves, more narrowly revolute, with a shorter point, not 
So much denticulate in the upper part, and also by its shorter capsule, It 
seems more closely connected with 2. oreganum Sulliv.; but from Sullivant’s 
description and drawings (Exped. Wilkes, Musci, 10, pi. 7, B) the latter has 
shorter stems, more serrate leaves, not twisted when dry, and a longer capsule,

Omnia integra, anguste sed distincte decurrentia, marginibus 
planis vel basi tantum subrevolutis: inferiora remota, parva,
