2, p. 167. C. crassifolia, Zam. Western Texas and New Mexico. We quite agree with Dr. 
Gray in regarding C. crassifolia as a mere variety of this species. Some of our specimens show 
a transition to C. Mississippiensis, Bosc, (C. integrifolia, Nutt ,) which Dr. Gray suspected was 
not distinct. 
Скілів (Momista) PALLIDA (n. sp.): ramis incano-puberulis ; spinis subgeminis rectis ; foliis 
ovatis vel ovato-oblongis pauci serratis integerrimisque puberulis crassiusculis breviter petiolatis 
basi acutiuseulis raro leviter cordatis; cymulis polygamis 3-5-floris petiolo paullo longioribus ; 
bacca ovata laevi glabra. (Тав. L.) Common in western Texas and along the Rio Grande, 
from Fort Duncan to the Gulf, and west to Magdalena in Sonora. It is called Grangeno in Neuvo 
Leon. (No. 1858, Wright; No. 3021, Berlandier.) А shrub 6—10 feet high, with numerous 
flexuous spreading branches. Thorns from 2 or 3 lines to an inch in length. Leaves 8-14 lines 
long, mostly acute, 3-nerved, minutely pubescent and somewhat scabrous on both sides. Flowers 
small, white; the lower ones of the cymule mostly male, with a rudimentary pistil ; the ter- 
minal one perfect. Styles thick, divaricate, cleft nearly half their length, the undivided portion 
rather shorter than the ovary. Berry about three lines long, orange, yellow, and red, with an 
acid pulp, which is edible but rather astringent. This species seems to be nearest the Brazilian 
C. orthocanthos, Planch.
