86 BRYACEJ3. [Fissidens. 



ovate, the upper much longer, linear-lanceolate, plicate to the 

 middle ; costa vanishing below the apex ; cells of the areolation 

 very small, each with a single papilla : pedicel very short : cap- 

 sule destroyed. — Coult. Bot. Gaz. iv. 151. 



Hab. Base of trees in a cypress swamp, Caloosa, Florida (J. Donnell 

 Smith, Austin). 



15. F. Garberi,Lesq.& James. Gregarious; i^lants simple : 

 leaves 4 to 8 pairs, slightly decurrent, oblong, the upper four times 

 longer than broad, plicate to the middle ; dorsal wing gradually 

 narrowed to the base ; lamina somewhat broader than the plicate 

 auricle, blunt at the apex, rarely short-acuminate, crenulate on 

 the borders by doubly papillose cells ; areolation round- 

 hexagonal, distinct, that of the perichretial clasping base of the 

 Yaginule larger, hexagonal-rectangular, in two or three rows : 

 capsule sub-erect, oval, pale brown, red at the orifice ; segments 

 of the teeth yellow. — Proc. Am. Acad. xiv. 137. 



Hab. On the bark of trees, Florida (Garber, J. Donnell SmitJ)). 



The inflorescence of this species is not positively ascertained. Schimper, 

 who examined the specimens with James, found it bisexual, while Austin 

 (Bull. Torr. Club, vii. 5), who had specimens from Florida which he con- 

 sidered the same species, describes it as pseudo-dioecious. 



16. F. Texanus, Lesq. Plants dark green, turning to black : 

 leaves 5 to 7 pairs, curved at the apex, broadly lanceolate-acumi- 

 nate, with a thick dark smooth margin ascending to the apex or 

 to near the slightly serrulate point ; costa stout, percurrent or 

 excurrent into a short mucro ; dorsal lamina broad, descending 

 to the base : male and female 2:)lants similar : capsule long-pedi- 

 cellate, oval, inclined, rarely erect, greenish brown, smooth; 

 lid conical, short-beaked, subincurved. — Herb. Sulliv. (1850). 



Hab. Texas (Wrig Jit). 



Eelated to F. inciirvus, but differing in the dark color of the plants, the 

 broad dorsal wing descending to the base, tlie broader leaves, and the 

 dioecious inflorescence. It differs from F. Tlallii, Aust., merely in the 

 entire margined leaves. 



17. F. obtusifolius, Wils. Plants densely gregarious or 

 closely aggregated-cespitiilose, bright green, simple or branching : 

 leaves 6 to 12 pairs, erect or turned to one side, very entire, not 

 margined, obovate, obtuse, with a broad nearly round pellucid 

 areolation, plicate to above the middle ; dorsal lamina gradually 

 narrowed, ending above the base; costa vanishing below the 

 apex : flowers terminal : capsule thick, oblong-ovate or obovate.
