Psychétria, Cofféa, and Nonatélea species, Sieb. 
Lin. syst. Penténdria, Monogynia. Calyx with an ovate 
tube, and an urceolate rather tubular limb, with an entire or 5- 
toothed border ; lobes or teeth joined together at length. Corolla 
with an elongated terete equal tube, and 5 short acutish erect or 
spreading lobes, which are usually callous at the apex, and val- 
vate in zstivation. Anthers 5, inserted in the middle or top of 
the tube of the corolla, inclosed or sometimes a little exserted. 
Stigmas 2, linear. Berries ovate, crowned by the limb of the 
calyx, containing 2 pyrene, hardly ribbed even in the dry state ; 
pyrene coriaceously-chartaceous or horny, oblong, marked by 
a furrow inside, convex on the outside, and furnished by a 
longitudinal crest in the middle, which is extended beyond the 
base, 1-seeded. Seed erect, with the transverse section arched, 
lunate, and compressed. Embryo at the base of a horny albu- 
men.—Glabrous shrubs, all natives of the Mauritius. Leaves 
Opposite or 3 ina whorl. Stipulas ovate, undivided or com- 
bined into a 4-cleft sheath. Flowers tubular, crowded and ses- 
sile on the tops of the branches, or disposed in terminal panicled 
Corymbs. This genus differs from Psychétria in the corolla 
being elongated, and from Palicoùrea in the corolla not being 
gibbous at the base, and from both in the urceolate or cam- 
panulate calyx. The habit is that of Gertnéra, but the characters 
are very different. 
* Flowers sessile, and crowded on the tops of the branches.
