BOTANY. 
have frequently two pairs of leaflets, which are furnished with 2-4 (sometimes more) very strong 
angular teeth. The fructiferous racemes are loose, and the pedicles of the dark-blue berries are 
half an inch long. The same plant grows between the Rio Grande and the Gila, where it was 
collected by Major Emory, and it is the B. pinnata of Sitgreave’s report. Colonel Fremont 
found it on the tributaries of the Virgin river. Dr. Gregg collected, near the battle-field of 
Buena Vista, what seems to be the same species, except that he says the berries are reddish; 
but they may be so only when they are unripe. 
Berberis Fendleri, Gray, FI. Fendl., p. 5. Mountain arroyas and bluffs on the Pecos, New 
Mexico; October. In fruit. The lower cauline leaves are spinulose-toothed, and the racemes 
appear not to have been many-flowered ; otherwise the specimens accord with those of Fendler. 
PAPAVERACEiE. 
Eschscholtzia Californio a, Cham.; Torr. & Gray, FI. 1 ,p. 664. Sandy plains, Cocomungo;

Eschscholtzia Douglasii, Hook. & Am. Bot. Beech., p. 320; Torr. & Gray, l. c. —Hill-sides 
Knight’s ferry, Stanislaus; May 8. We find the acumination of the calyx nearly as long as 
in the preceding species. The flowers, too, are smaller than in the Oregon plant. 
Eschscholtzia Douglasii, Var. tenuifolia. E. tenuifolia, Benth. in Trans. Hort. Soc. {ser. 2) 
1, p. 408. With E. Douglasii, from which it differs only in its usually very short stem, long 
sub-radical peduncles, and very narrow segments of the leaves ; characters which are by no 
means constant. What appears to he a diminutive form of this variety, was collected on Wil¬ 
liams’ River of the Great Colorado, early in February.

having 11 or 12 stamens, and in its much larger flowers.
