 Hab. Pacific Isles, Nightingale, Hook, Herb. 



Tufts wide, dense, olive-brown. Stems scarcely 1 inch 

 long, much branched. Margins of the stipules flexuose. 

 Barren perichcetia erect, cylindrical. In L. trifaria, Nees, 

 the leaves are not so long, have no acute point, and the cells 

 are far larger.

 Hab. Demarara. Greville's Herb. 



Patches wide, olive-brown. Stems 2-3 inches long, often 

 with very short branches. Monoicous. Perigonia linear, 

 lateral. Perichmtia on short branches. This is larger than 

 our L. longiflora, the leaves are more distant, more patent, 

 and more undulate, their lobules are more minute, the calyces 

 ar e not so narrow at their bases, and the perigonia do not 

 °ccur in the course of the shoots, but form lateral spikes. 

 This is quoted in Synopsis Hepat. p. 364, under L. elegans, 

 Gottsche, a plant, as it would appear, whose locality and 

 fructification are unknown ; but whatever be Dr. Gottsche's 

 species, ours seems to differ from it, if we may judge from the 

 characters assigned to it, by the branches not being fascicled, 

 °y the recurved leaves, by the stipules being contiguous but 

 scarcely imbricated, and less than half the size of the leaves, 

 whilst their lobes are not acute.
