361. Barbula henrici E. A. Rau, n. sp. (Bull. Wash. Coll. Lab. Nat. Hist. I, 172): 

 "Dioecious? plants short, branched, closely cespitose, canescent from the white ex- 

 current costas; leaves concave, short spatulate; costae keeled, filamentose, near apex 

 of leaf, excurrent portion as long as the leaf, hyaline, serrate; areolation of leaves 

 quadrate and chlorophyllose above, hyaline and elongated toward the base; leaves 

 spreading when moist, imbricated when dry. Habitat: Rocks, Saline county (Joseph 

 Henry). Although without fruit, it appears to be a distinct species belonging to 

 the section Chloronotse. It differs from Barbula chloronotos, Bruch, in its more 

 canescent appearance, shorter and more obtuse leaves, laxer areolation, longer ex- 

 current and more serrate costae. Plants bearing archtegonia only were sent; it is 

 therefore desirable to secure fruiting specimens to complete the diagnosis."
