CHEILOLEJEUNEA VERSIFOLIA 145 
From the first of these species it differs in the shape of its leaf- 
lobe, in its smaller lobule, in its smaller and more deeply cleft un- 
derleaves and in its more flattened perianth, the antical face being 
plane or nearly so. It is a much larger plant than Microlejeunea 
lucens, and differs also in its autoicous inflorescence, in the shape 
of its leaves, underleaves and perichaetial bracts and in its slightly 
larger leaf-cells, usually with more conspicuous thickenings. From 
Euosmolejeunca duriuscula, it differs in its paler color and more 
delicate texture, in its autoicous inflorescence, in its slightly larger 
leaf-cells and in the shape of its leaves and underleaves. 
The species is one of those interesting links between genera 
which are so frequent inthe Lejeuneae. Some of the reasons for 
placing it in Chedlolejeunea rather than in Hygrolejeunea are stated 
by Schiffner,* who maintains that, although the leaves and the leaf- 
cells show an affinity with Hygrolejeunea, the underleaves and 
perianths are more like those of  CheZolejeumea. Apparently 
Spruce was also a supporter of this view, for he described a South 
American hepatic under the name Z. (Cheilo-Lejeunea) phyllobola.t 
Unfortunately the plant which he studied was not Lejeunea phyllo- 
bola Nees & Mont. but an undescribed species, afterwards distributed 
under a manuscript name in Hepaticae Spruceanae. There seems 
to be in fact no authentic record of C. phyllobola from South America. 
Specimens from Brazil are quoted in the Synopsis, but these, ac- 
cording to Stephani,t are referable to Z. oxyloba Lindenb. & 
Gottsche.
