 albumen-layer. — Hab. S. Kitts !, Sw. ; Trinidad !, Pd., Cr., in the mountains of S. Anns ;

XXX. BHAMNE.E. 



Calyx valvate, 5-4-Iobed. Stamens alternate with the calyx-lobes, inserted into the 

 margin of a perigynous disc. Pistil syncarpous: ovules 1 (-2) iu each cell. Embryo 

 straight: radicle inferior; albumen scanty or none. — Shrubs or trees; leaves simple, sti- 

 pulate. 



Gouania dominyensis yields a stomachic drug, Colubrina reclinata, a fermented drink 

 {Mabie of S. Lucia). Sarcomphalus laurinus is one of the best timber-trees of Jamaica. 



1. FRANGULA, T. 



Calyx free from the ovary, at length circumscissile, leaving its cupulate tube below the 

 fruit. Petals cuctdlate ; disc thin. Drupe 3(2-4)-pyrenous : seeds not grooved, with a la- 

 teral raphe ; cotyledons flat. — Leaves alternate ; flowers clustered in axillary cy mules. 



1. P. sphaerocarpa, Gr. Leaves elliptical, poiutleted, serrate, glabrous; cymules 

 umbelliform, exceeded by the petiole : peduncle nearly as long as the pedicels, simple, or 

 simply divided; flowers perfect, 5-androus; calyx shortly campanula te : lobes as long as the 

 tube, twice as long as the bilobed petals and stamens; style simple; stigma 3-globose; 

 drupe globose : " seeds oblong."— Ceanothus, DC. Rbamnus sphaerospermus, Sw. /—Habit 

 of Rhamnus alpina: 10'-15' high, unarmed; leaves 4"-3" long, rounded at the base : prin- 

 cipal veins 8-10 on each side, curved near the margin ; petioles, younger branchlets, pedi-
