Hab. Cold and subalpine regions, in fissures of rociis; not rare. 



2. D. inclinatum, Bmch & Schimp. Differs from the 

 preceding in its soft irregular dark green tufts; the leaves 

 close, shorter, more narrowly subulate and minutely serrate at 

 the apex; the male flowers at the base of the pericha3tium, 

 which is composed of three sheathing leaves ; the capsule cer- 

 nuous, shorter ovate ; and the teeth broader, strongly articulate, 

 bifid or cribrose. — Bryol. Eur. t. 194. Swartzia i?idmata,

Trichostonmui (?) scitidum, Austin (Coult. Bot. Gaz. i. 29), described 

 as small with slender stems, the leaves distichous, erect, subsheathing at 

 base, spreading and undulate, abruptly linear-canaliculate, scabrous and 

 papillose, erose-serrate at the apex, is apparently a form of this species. 

 The description is made from sterile plants found on dry shaded lime- 

 stone rocks at the zinc mines of Odenburg, New Jersey. The author 

 remarks tlaat tlie leaves are much like those of Distlchliim inclinatum, 

 but they are more undulate-flexuous, less solid, not so acute, and the 

 papillae of the surface are larger. 



^32. EUSTICHIA, Brid. (PL 2.) 



Plants with the aspect of Fissidens, more or less densely 

 gregarious; stems simple, rarely forking, flat, radiculose and 

 bulbiform at base. Leaves distichous, densely imbricate, cari- 

 nate-plicate, erect, smooth, glossy ; costa thick, compressed 

 toward the base into a narrow lamina, more enlarged toward 

 the apex, percurrent or vanishing below the apex in the stem- 

 leaves, passing in the floral leaves into a long flexuous lorate 

 acumen ; areolation oblong-elongated, hyaline below, quadrate- 

 hexagonal and chlorophyllose above. Flowers dioecious, ter- 

 minal, gemmiform ; antheridia and archegonia long, slender, 

 with few short piliform paraphyses. Calyptra cucullate. Cap- 

 sule oval or obovate, on a short flexuous pedicel. Lid flat, con- 

 vex when moistened, obliquely and narrowly rostrate. Peri- 

 stome none.
