 Thysanomitrium flexuosum R. saxicola RABENH. Deutsch. Kr. fl. ii, s. 3, 149 (1848). 



Dioicous; densely caespitose, % 2 in. high, pale or yellow-green 

 above, pale brown with rufous tomentum at base ; innovations pro- 

 ducing at apex fragile fasciculate branches with long narrow leaves. 

 Leaves very dense, erecto-patent, straight, fragile deciduous, very thin 

 and whitish at base, with a silky gloss, narrowly lanceolate, shortly 

 setaceous, denticulate towards point ; nerve lightly sulcate at back, of 

 3 strata of cells, the two anterior large and hyaline ; cells at base lax 

 and rectangular, above the marginal are very narrow and elongated, the 

 rest subquadrate, upper oblong elliptic. Caps, bent down among the 

 comal leaves by the cygneous seta, oval subpyriforum, lightly sulcate, 

 olivaceous ; calyp. sparingly fringed ; lid conico subulate, pale red, 

 oblique ; annulus broad. Male pi. resembling that of C. pyriformis.

Plants more robust and leafy than the last, and with fine branched pale 

 radicles on the stem, the expanded lamina narrower at base, J or ^ length 

 of leaf, and gradually narrowed in the upper part with coarser areolation. 

 Considerable variation in height and density is met with in this species but 

 no definite line can be drawn between the two forms densus and fragilis.
