I failed to discover the Z. lycioides which I judge to be very rare, if 

 at all present, in Texas. 



Ccndalia obovata, Hook. (.Brasil; Logwood.) 



Shrub at San Antonio and westward, often with the preceding and 

 nearly as common. Becomes a small tree, 20 feet high, on the Lower 

 Eio Grande and along the coast. Wood very hard, of a brick-red color, 

 containing a red (some say purplish) dye. Evergreen of hardy growth 

 in dry, rocky soil, with stiff aud thorny branches, making pretty and 

 effective hedges. The small, deep-red berry (capul negro) is acidulous, 

 nice to eat and makes fine jelly. 



Condalia spathulata, Gray, and C. Mexicana, Watson. 



Evergreen shrubs, smaller than the preceding, the former common in 

 Western Texas, the latter on the Lower Eio Grande. Both horridly 

 spinose and excellent hedge-plants. Berries the same as in the pre- 

 ceding. 



Ceanothus Fendleri, Gray. 



Very thorny and spreading bush in foot-hills beyond the Pecos ; also 

 a possible hedge plant. 



Karwinskia Humboldtiana, Zucc. 



The Coyotillo of the Mexicans on the Lower Eio Grande ; common 

 on the Pecos near its mouth and thence eastward to the coast. Shrub 

 with beautifully penninerved, ovate leaves, and brownish- black berries 

 said to be very poisonous. The virulent principle lies in the seed, the 

 pulp being innocuous. The symptoms are those of paralysis of the 

 spinal cord, primarily affecting locomotion. 



OLEACEiE. 



Fraxinus viridis, var. Berlandieriana, Torr. (Texas Green Ash.) 



The most common Ash of Southern and Western Texas. Large tree 

 in the Chenate Mountains, smaller in the Limpio and Guadalupe Mount- 

 ains ; found also as a medium-sized tree on the Pecos, Devil's Eiver, and 

 most streams farther eastward to San Antonio j occurs sparingly on the 

 Lower Eio Grande, the Gulf Coast, and the water-courses of Southeast- 

 ern Texas. 



Wood hard, tough and close-grained, but rather devoid of elasticity. 



Fraxinus pistaciaefolia, Torr. 



Low, spreading tree, with trunk 1 foot or more in diameter; fre- 

 quently planted about El Paso and down the Eio Grande to San Eliza- 

 rio, on account of its quick growth. Also seen as a small tree at the 

 base of the Guadalupe Mountains. 



Wood softer than that of the preceding. 



Fraxinus pubescens, Lam. 



Seen as a small tree on the summit of the Guadalupe Mountains, and 

 nowhere else.
