          B. julaceum. Stme branched; leaves closely imbricated, broadly [soate?], concave, entire, obtuse, nerve running nearly to the point, capusle elavate, pendulous; lid conical.

 The characters just recited we have found constant in our B. julaceum , & we therefore cannot agree with cllohr & Schwaegrichen who with Linnaeus considered it as merely a variety of B. argenteum. It is not in the shape of hte leaves & of the capsule alone that they differ, but our plant is larger & more slender, of a yellowish green color, resembling that of Hypnum stramineum & the leaves are of the same color & texture throughout. 
 This plant so is never found on walls & roofs, as is commonly the case with B. argenteum, but on the side of streams in moutnainous situations. B. alpinum. Stem elongated, ramose; leaves ovato-lanceolate, nearly obtuse, points; capsule cylindraceo-obovate,  pendulous, lid conical.

 The leaves of this species which are of a singular purplish-brown color, & dense strucutre in all our specimens are never completely acute, as represented by schwaegrichen & most authors. The stems approach in rigidity & habit those of some of the Polytrichs. 
 B. crudum. Stem short; leaves lanciolate, plane, acute, serrulate at the point, nerve disappearing below the summit; capsule oblong, pendulous; lid conical.
