CATALOGUE. 107 
half an inch long or often more: spikes cylindrical, usually dense, shortly 
pedunculate, 2 to 4 inches long, 1—3-fruited: flowers a line long: pods 4 to 
6 inches long or more, stipitate, straight or curved, narrow, flat, at length 
thickened and pulpy within—From Texas to Southern California and south- 
ward to Chili and Brazil; at Ash Meadows, Southern Nevada, in 1871, and 
in the Gila Valley, Rothrock (320). 
Prosopis PUBESCENS, Benth. (Lond. Journ. Bot. v, 82). (Strombo- 
carpus pubescens, Gray.)\—New Mexico to Southern California; at Ash 
Meadows, Southern Nevada, 1872. 
Desmantuus Jamesu, Torr. & Gray (FI. i, 402)—Slightly puberu- 
lent, erect or decumbent, a foot high or less: pinne 3 to 6 pairs, the 
lowest approximate to the stem; leaflets 8 to 13 pairs, oblong, acutish, not 
veined, 2 lines long or less; gland large, oblong; stipules very small: heads 
large, 3 or 4 lines in diameter without the stamens, on peduncles an 
inch in length or often much less: pods linear, straight or nearly so, 
3 or 4 inches long, obtuse or acute, 12—16-seeded—Var. (?) FxNDLERI, 
with smaller fewer-flowered heads, and the thick pods 2 inches long 
or more, and usually 8-12-seeded—From Arkansas and New Mexico 
westward; at Cooley’s Ranch and Camp Apache, Ariz., Loew (1116) 
and Rothrock (255), and the variety at Rocky Cafion, Ariz., Rothrock (291), 
and Cafion del Diablo (192); the last referred doubtfully in the catalogue 
to D. velutinus. This variety is identical with 179 Fendler and 169 Wright, 
considered by Dr. Gray (Pl. Wright. i, 63) to be a form of D. Jamesii, but 
placed rather under D. reticulatus by Bentham (Rev. Mim.). The earlier 
reference appears to be the better.

puberulent, with a pair of short stout recurved prickles below each leaf: 
pinne 4 to 7 pairs; leaflets 10 to 15 pairs, narrowly oblong, obtuse, a line

* Mimosa, Linn.—Flowers perfect or polygamous. Culyx mostly minute, rarely campanulate, 
shortly toothed. Petals connaté, valvate. Stamens as many or twice as many as the petals, distinct, 
; pollen-grains numerous. Style filiform. Pod oblong or linear, membranaceous or coriaceous, 
compressed, the 2 valves at length separating from the persistent margin.— Herbs or shrubs, often armed ; 
leaves bipinnate, the petioles without glands and the pinn@ stipellate ; flowers small, sessile in globose 
or cylindrical spikes, on solitary or fascicled axillary peduncles, or the uppermost racemose.—BENTH. &
