264 Evans: HEPATICAE OF PUERTO RICO 
about 14 in short diameter; elaters about 9m in diameter. 
(PLATE II, FIGURES I-8.) 
On leaves of shrubs and trees. Near Cayey, Evans (70, 71, 
and 72, in part). Mayagiiez, E. G. Britton & D. W. Marble 
(536, in part). Widely distributed in the American tropics and 
especially abundant in Brazil, where it has been found by numerous 
collectors. The following localities may also be noted: Trinidad, 
Crueger (the type station); Cuba, Wright; Jamaica, Underwood, 
Evans; Andes, Spruce. 
Spruce referred the present species with some question to 
Lejeunea obliqua Nees & Mont.* and described it fully under this 
name, quoting his manuscript species, L. erigens, as a synonym. 
A few years later he cast doubt on his earlier determination by 
distributing specimens under the name L. erigens, but apparently 
he never published this name formally. L. obliqua was described 
from sterile specimens collected by Leprieur in French Guiana. 
The authors of the Synopsis Hepaticarum considered it a mere 
synonym of Lejeunea cuneata Lehm. & Lindenb.,f} which was 
described from Mauritian plants, also sterile, and Montagne ac- 
cepted their decision in his Sylloge, published in 1856. Unfor- 
tunately no specimens of L. obliqua can be discovered in the 
Montagne herbarium at Paris, and there is therefore no way of 
deciding whether the French Guiana plant is identical with L. 
scabriflora or not. The writer has also been unable to secure 
specimens of L. cuneata for examination, but a drawing made from 
the original material and kindly communicated by Stephani shows 
conclusively that the plant from Mauritius is widely distinct from 
L. scabriflora. The leaves in L. cuneata, for example, are much 
broader and might accurately be described as orbicular-ovate.
