48 BRYACE.E. [Brnchia. 



oblong or obovate at base, more gradually acuminate, all very- 

 entire, glossy ; costa enlarged upward, somewhat excurrent : 

 capsule exserted, pyriform-elliptical, somewhat long-beaked, 

 the comparatively long collum gradually narrowed to the long 

 straight pedicel ; calyptra smooth, mitriform or subcucullate, 

 lobed, covering a third of the capsule. — Biill. Torr. Club, v. 21. 



Hab. Near Houston, Texas (E. Hall), 



A very fine and distinct species, recognized at once by its short appressed 

 imbricate leaves, and the cajisule exserted on a long straiglit pedicel. 



9. B. Donnellii, Aust. Paroecious, of the size of I^. flex- 

 uosa : leaves more abruptly subulate from a nearly round base, 

 distinctly papillose : pedicel more strict : capsule 2-colored, 

 with a thicker and longer collum : spores nearly twice as large. 

 — Bull. Torr. Club, vi. 144. 



Hab. Florida [J. Donnell Smith). 



This species has a long thick collum and large spores, as in B. Texana, 

 which, however, has much shorter smooth leaves. It also lias the in- 

 florescence and large spores of B. Hallii, but the collum in this last species 

 is much shorter and the leaves are smooth. — (Austin). 



10. B. Texana, Aust. Compared with the preceding it 

 differs in the shorter stems ; the lower leaves narrower, longer- 

 lanceolate-acuminate and flexuous, the upper much longer, oval 

 at base, abruptly narrowed and very narrowly subulate-canalic, 

 ulate upward, flexuous when dry ; costa dilated upward, per- 

 current ; areolation longer and narrower below, rapidly passing 

 above to very small minutely granulose cells : capsule a little 

 shorter, with a more slender beak and a thicker collum abruptly 

 narrowed to the pedicel. — Bull. Torr. Club, v. 21. 



Hab. Near Houston, Texas (E. Flail). 



11. B. brevipes, Hook. Resembling B.flexuosa in aspect, 



but distinguished by its small size, the rigid leaves more enlarged 



at base, abruptly narrowed into a longer awl-shaped point 



entirely filled by the costa, by the shorter pyriform immersed 



capsule truncate at base and sharply apiculate, by the very short 



pedicel, and larger spores. — Icon. PI. t. 231 ; Hook. & Wils.,

Muse. 24, t. 14. 



Hab. Louisiana {Drummond); South Carolina, on sandy ground 

 (Ravenel); Petersburg, Virginia (James). 



12. B. brevifolia, Sulliv. Subcespitose, the stems very 

 short, erect, densely foliate ; lower leaves minute, ovate-acumi-
