365. Cotuprina Texensis: caule ramosissimo, ramulis 
divaricatis cinereis ; foliis elliptico-cuneatis oblongisve glandu- 
loso-denticulatis breviter petiolatis alternis plerumque in nodos 
fasciculatis supra pubescentibus nunc glabratis subtus sericeo- 
villosis fulvis penniverviis basi trinervatis ; pedunculis fascicu- 
latis paucis petiolo longioribus calyceque (laciniis patentibus) 
villosis. — Rhamnus? Texensis, Torr. & Gray, Fil. 1. p. 263. 
— Prairies and borders of woods on the Guadaloupe and 
Comale. (Also communicated by Mr. Wright.) Flowers in 
May; fruits in June. — Shrub 2 to 5 feet high, rigid. Leaves 
three fourths of an inch long. Pedicels two to four together 
from the centre of the cluster of leaves, two or three lines 
long in flower, in fruit becoming half an inch or more in 
length. Calyx-tube adherent to the ovary and filled with the 
broad annular disk; the lobes widely spreading, broadly tri- 
angular-ovate, nearly herbaceous. Petals unguiculate, shorter 
than the subulate-filiform filaments, scarcely equalling the 
calyx. Styles three, sometimes four, united at the base, 
stigmatose on the inner face above. Ovary immersed in the 
adherent disk. Fruit dry and capsular at maturity, tricoc- 
cous, somewhat three-lobed, globular, girt at the base by the 
persistent and adherent base of the calyx, three-seeded. 
Seeds lenticular, plano-convex, shining. Cotyledons plane; 
albumen very thin. This shrub, of which we at length are 
provided with complete specimens, has nearly the flowers of 
a Zizyphus, but the fruit of a Ceanothus. It appears to be a 
genuine Colubrina. 
366. Conpauia opovata, Hook. Ic. Pl. t. 287; Torr. & 
Gray, Fl. 1. p. 685; Gray, Gen. Ill. 2. t. 164. “On slopes,

in flower and fruit.
