278 MR. A. W. UENXETT ON THE GENUS HrBKOLEA. 



berrima, reticulato-venosa. Corolla parva, glabra- Ovarium minu- 

 turn, glabrum. Styli duo, decidui. Capsula bilocularis, parva, glabra, 

 globosa, bilinearis, in calyce persistente inclusa, eoque dimidio brevior. 



From swamps, Nupe. Though only represented by two speci- 

 mens in tlie Kew Herbarium, I have no hesitation in describing 

 this as a distinct species from the last. The very large, triangular, 

 conspicuously-veined sepals, completely enclosing the ripe cap- 

 sule, at once serve to distinguish it, combined with the inflores- 

 cence being much laxer, more diffuse, and not corymbose, the 

 flowers smaller on longer pedicels, and the leaves shorter and 

 somewhat broader. The deciduous styles may also possibly furnish 

 another character. 



To complete this review of the genus Ht/drolea^ and to facilitate 

 a comparison with the descriptions of those who have worked at 

 it before, I append a list of excluded species and synonyms.

The description is exceedingly imperfect ; and the two charac- 

 ters of opposite leaves and solitary flowers would seem to remove 

 it altogether from this genus.
