Cryptogamic Plants from the Ionian 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resemble those of an unpublished Nepalese species in my pos- 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. 
1. B. Donianum, caule breviusculo robusto, innovationibus bre- 
vibus ramoso; foliis densis summitate praecipue aggrega- 
tis, erecto-patentibus, obovatis, acutis, marginatis, apice 
denticulatis, nervo excurrente ; seta elongatà; theca cla- 
vatâ pendulà ; operculo brevi, conico. Tasg. III. f. 6. 
On the ground? (No station given.) 
Stem about half an inch in height, robust, covered with brown 
tomentose radicular fibres, branched with very 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. 
Fruitstalk nearly two 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 cilia.
