232 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [ Mauritia 
UNRECOGNIZED SPECIES. 
LEPIDOCARYUM TRISTICHUM Spruce ; mentioned by Barb. Rodr. in Sertum Palm. 
i, 11. (Spruce to my knowledge never published a Lepidocaryum with that specific 
name.) 
A Lepidocaryum figured by Drude in Mart. Fl. Bras. iii, II, t. LXVIII, f. II, 
under the name of L. tenue, is probably a distinct species, owing to its female (or 
pseudo-hermaphrodite) flowers having stamens with short filaments and elongate 
linear anthers. 
The genus Lepidocaryum is as yet very imperfectly known, and probably the 
species are more numerous than it is generally believed, although not offering 
conspicuous diagnostic characters. ©
