Cryptogamic Plants from f/ie Ionia» Islands. 345 



In every point of view this moss seems sufficiently distinct. 

 The leaves are very strikingly vascular, and in this respect 

 resemble those of an unpublished Nepalese species in my pos- 

 session.

On the ground? (No station given.) 



Stem about half an inch in height, robust, covered with brown 

 tomentose radicular fibres, branched with a ery short inno- 

 vations, leaves few on the lower part of the stem, densely 

 crowded and somewhat spreading at the top : they are 

 rather broadly obovate (those of the innovations narrower), 

 pointed, slightly concave, denticulate towards the apex, the 

 margin decidedly thickened : nerve strong, and running- 

 more or less beyond the point, but never hair-like or trans- 

 parent. The colour of the lower leaves is reddish ; that of 

 the upper ones a dull green, which is much brighter under 

 the microscope, their base being moreover frequently of a 

 beautiful deep pink. The nerve and thickened margin are 

 also often reddish. The reticulation is small, the cellules 

 roundish, except at the base, where they are elongated. 

 Fruit stalk nearly tvvo inches long, dark red. Capsule pen- 

 dulous, brownish-red, large, clavate, the lid shortly and 

 obtusely conical ; this part, however, I have not seen in a 

 mature state. Inner peristome equal in length to the outer 

 one, each tooth composed of from 3 to 5 ribs terminating in 

 a point, and connected by transverse bars. I could not 

 perceive any alternating ciliœ.
