365. Colubrina 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. fy Gray, Fl. l.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.
