*42 ?ENTANDRIA MONOGYNIA, Alyxia, 



rarely sub-acute apex, remarkably firm and leathery, dark-green and 

 shining above, somewhat glaucous underneath; rib keeled, nerves 

 capillary, remotish. — Petiol about half an inch long, slightly furrow- 

 ed, even at the base. — Flowers white, disposed in short, axillary, sim- 

 ple or fascicled racemes. Bractes ciliate, blunt. Lacinia of the 

 calyx ovate, acute, ciliate. — Tube of the corolla swelled under the 

 limb ; throat shut with five, two-lobed protuberances. Lacinice ob- 

 long-falcate. Anthers sessile at the upper end of the tube. — Ovary 

 single, ovale, two-celled, with several ovula attached to a septal 

 placenta. Stigma oblong, blunt, fleshy. 



Obs. I strongly suspect that this and the nest species will be found 

 to belong to Rauwolfia, or to constitute a new genus. This point 

 can, of course, only be decided, when the fruit shall be obtained. 

 The disposition of the leaf-vessels on which I place great reliance in 

 determining generic and natural affinities, is the same as that in 

 Alyxia and Hunteria ; the structure of the calyx, ovary, and stigma 

 correspond with that of the last mentioned genus. — N. W.

Leaves opposite oblong, terminating in a linear blunt acumen,

 or acute, five to six inches long, leathery, glossy above, glaucous

 geminate nerves, which unite close under the margin by mean3 of a
