 Syrrhopodon Leanus, Sulliv. Muse. Allegh. n. 172. 



Hab. On much decayed logs or soft woody earth in forest swamps of 

 the Middle States and westward ; not common. 



5. 0. Hallii, Lesq. Plants in compact pale green glossy- 

 tufts ; stems short, 2 cm. long, many times clichotomous, tomen- 

 tose to the apex : leaves strict, rigid, linear-lanceolate, tubulose, 

 very entire at the apex, and smooth throughout; casta very- 

 broad, covering the whole lamina except two small auricles at 

 base composed of a few colored inflated cells. — Porter & Coult. 

 Flora of Colorado, 155. 



Hab. High ridges of the Colorado Momitains [E. Hall). 



Eeserahling C brevipes (Schimp. Bryol. Eur. Suppl. Campylopus, t. 2), 

 but differing in the broader costa, and the leaves constricted at base into 

 short obtuse auricles with one or two rows of colored cells. 



6. 0. frigidus, Lesq. 1, c. Resembles the preceding species 

 in the broad dilated costa, but differs in the longer narroAver 

 leaves, slightly- denticulate at the apex, open, flexuous when dry, 

 and scabrous on the back ; alar cells round. 



Hab. Same as the last {E. Hall). 



7. C. subleucogaster. Plants loosely cespitulose, dirty 

 yellow ; stems short, slender, simple in the lower part, divided 

 at the apex into short capitate" branchlets composing a crispate 

 bristly tuft : lower leaves minute, erect, the comal longer, ovate- 

 acuminate with a flat broad nerve passing up to a gradually 

 narrowed canaliculate subulate strict point, serrulate at the 

 apex ; basilar cells large, pellucid, regularly hexagonal, with a 

 few smaller quadrate inflated yellowish ones underneath, the 

 alar numerous, very loose, brownish-colored, pellucid, slightly 

 excavated ; perichretial leaves much larger, sheathing or convo- 

 lute at base, loosely reticulate, with a long-flexuous more 

 coarsely subulate point. — Dicranwn subleucogaster, Muell. 

 Bull. Torr. Club, v. 50. 



Hab. On M-et clayey ground; Mobile, Alabama (MoTir). 



This species differs from the European Dicranwn leucogaster, Muell., 

 in the more flexuous thicker longer hairy stems, the alar cells whitish and 

 loose, and the others smaller, 



8. C. Donnellii. Differs from the last in its tawny green 

 color, the leaves more open, subfalcate, longer and more abruptly 

 narrowed, often spinulose-serrate and whitish at the apex, the 

 costa narrower, etc. — Dicramcm Donnellii, Aust., Coult. Bot.
