(Tab. XXI. figs. 4, 5.)—St. Vincent, Richmond Peak (355), in 
Frichomane. Dominica, Roseau Valley (60), “a meagre variety 
differing in the nearly equal leaf-cells—not wider and laxer 
about the middle of the leaf .... LZ. guadalupensis is the only 
Prionolejeunea with quite entire leaves; but the compresso- 
trigonous perianths with toothed margins, seated on a short 
proper branch, declare its affinity with Z. denticulata, &c.” 
[Spruce in litt. Nov. 6th, 1893.]

1892.—St. Vincent, Souffri¢re (227). Dominica, Morne 
Micotrin (86). 
This plaut, which was first found in the Eastern Peruvian 
Andes, agrees with L. microdonta, a common Amazonian species, 
in the very short fertile ramulus putting forth a minute subfloral 
innovation, but differs in its abruptly apiculate (uot verv obtuse) 
leaves, and its deeply obcordate perianth, which is bordered in 
the upper half by a narrow incised wing.
