IIai3. Old bayous, Western Kentucky (Lesquereux). 



A well marked species, generally confounded with F. disticha, but 

 readily distinguislied by its slender delicate babit and its long and narrow 

 capsule. 



10. F. disticha, Hook & Wils. Plants more robust than 

 in the last, )nore divided and diffuse, or pinnately branching 

 above : leaves more open, broader, concave, twisted at the 

 slightly serrulate apex; perichjetial short and lacerate: male 

 flowers very numerous: fruits rare : capsule somewhat broader; 

 teeth 12-16-articulate ; the cilia transversely latticed from the 

 middle upward. — Drumm. Muse. Amer. (Coll. II.), n. 151;

11. F. hypnoides, Hartm. Plants slender, with few 

 branches and short spreading branchlets : stem-leaves distant, 

 open, nearly flat, ovate-lanceolate, sharply long-acuminate, 

 narrowly lanceolate when young, loosely reticulate : capsule 

 very small, elliptical, thin, naked to the middle ; teeth narrow, 

 densely articulate, entire, purple ; cilia narrowly latticed, blood- 

 red.— Skand. Fl. ed. 4, 434; Bryol. Eur. t. 432.

101. DICHELYMA, Myrin. (PI. 4.) 

 Plants with distant subdistichous branches. Leaves narrow, 

 long lanceolate-subulate, falcate or complicate, narrowly costate ; 

 arcolation rhomboidal. Flowers dioecious ; perichaetium very 

 long, the outer leaves imbricate, the upper convolute. Calyptra 

 dimidiate, descending to below the capsule and connate at 

 base, or short and cucullate. Capsule long-pedicellate. Teeth 

 of the outer peristome long-linear, more or less densely articu- 

 lated, and splitting along the divisural line; cilia longer than 

 the teeth, latticed above or appendiculate.
