88 HYPNACEAE 



B. rutabulum B. & S. Common on ground and stones in 

 wet or swampy places. Early winter. A variety approaching 

 B. rividare from S. Id. was issued as No. 421, X. Am. Musci PI. 



Yar. turgescens Limpr. Swamp, New Dorp, S. Id.!! 



B. salebrosum (Hoffm.) B. & S. Common, occurring on all 

 sorts of substrata in rather damp places. Autumn-winter.

 Latham, Prospect Park!!, and New Lots, Brainerd (26014), on 

 L. Id.; Closter, N. J.. Austin!!; Clifton, X. J., Xash, Bx! 



BRYHNIA Kaurin 



Closely related to Brachythecium, but distinguished by 

 shorter leaf cells (4-6: 1), papillose at the angles by the pro- 

 jecting cell walls. The papillae are sometimes wanting in B. 

 Novae-Angliae which leads M. Cardot to refuse this group 

 generic rank. 



Key 



Branch leaves acute to short acuminate, apex twisted Novae-A ngliae 



Branch leaves longer acuminate, apex not twisted graminicolor 



B. X'ovae-Angliae (Sull. & Lesq.) Grout. {Hypnum Xovae- 

 Angliae Sull. & Lesq.) Common on soil in swamps. Winter. 



B. graminicolor (Brid.) Grout. "On banks of deep shaded 

 ravines, common but rarely fertile," Muse. App. 334; Egbert- 

 ville, S. Id., E. G. B.. Bx!; "Bath, Brainerd," Flora L. Id.; 

 Canaan, Ct., Xichols, Bx! 



CAMPTOTHECIUM B. & S. 



Plants closely allied to Brachythecium but for the most part 

 distinct to the casual observer by reason of the bright golden or 

 yellowish green silky luster and strongly plicate leaves, which are 

 usually slender and have as a rule narrower leaf cells; seta rough 

 or smooth. Our only species is: 



C. nitens (Schreb.) Schimp "Peat bogs, near Sparta, X'. J." 

 muse. App. 307. Should be found nearer in cool bogs.
