MR. RICHARD SPRUCE'S HEPATICE ELLIOTTIAN E. 343 
smooth (eplicate) perianth, dilated at the inflexed and corrugated 
apex. It occurs in the Antilles, and at the roots of the Eastern 
Andes, extending as far south as Bolivia. It creeps over ferns 
and the living leaves of trees.

This species has a wide distribution in tropical America, being 
found in the Antilles and Bolivia, yet like Z. xanthocarpa it has 
not been noted on the Equator. It is replaced in the lower 
Peruvian Andes by an allied but very distinct species—L. devoluta 
(Trans. Bot. Soc. Edinb. xv. p. 236, tab. 9). The Hygrolejeunee of 
South America are chiefly montane in habit. Of a dozen species 
gathered by me only two descend into the plain. All Mr. Elliott’s 
species belong to the highest regions explored by him.
