described his CL chamaecristoides, basing it on this same plant of Houston’s. In 1830 
Chamisso & Schlechtendahl described their Cassia cinerea from a plant growing in 
the sands of Vera Cruz, identical with Houston’s plant. This name.has since been 
used, but must now give place to the earlier name of Collardon. Bentham has 
referred C. chamaecristoides to C. procumbens, but surely this isa mistake. In a note 
he states that some of the larger specimens seem to approach (. cinerea.

FIVE NEW SPECIES OF BRONGNIARTIA. 
The genus Brongniartia is chiefly Mexican and in Mexico is repre- 
sented by many species. Of these Mr. Hemsley enumerated 17 in the 
Biologia Centrali-Americana, but at present the number described 
(including the following) reaches about 30. While a synopsis of the 
genus was being prepared several additional species were discovered, 
five of which are here described. 
Brongniartia peninsularis Rose, sp. nov. 
A shrub, 2 to 3 meters or more high with many slender, more or less zigzag, 
branches, when young densely silky-pubescent; stipules leaflike, broadly lanceolate, 
10 mm. long; leaflets 5 to 13, lanceolate, acute, 1 to 2. cm. long, with appressed cin- 
ereous pubescence on both surfaces; flowers axillary; peduncle 2 to 2.5 em. long, 
pubescent, bibracteate at base; bracts probably large; calyx tube glabrous, the lobes 
pubescent on the margin and inner surface; corolla 1.5 em. or more long; pods gla- 
brous, shining, 4 cm. long. 
Collected by EK. W. Nelson and E. A. Goldman about 5 miles southwest of El 
Potrero, Lower California, October 31, 1905 (no. 7236). 
Type U. 8. National Herbarium no. 5653821. 
This species is quite unlike B. trifoliata, the only other species from Lower Cali- 
fornia, as well as the other Mexican species. 
Brongniartia .asiocarpa Rose, sp. nov. 
Low bush, 30 to 40 cm. high; young branches densely pubescent; leaves small for 
the genus; leaflets 11 to 17, oblong to orbicular, 5 to 7 mm. long, obtuse, mucronate, 
glabrate and shining above, somewhat hairy beneath, rather thick, more or less 
reticulate on both surfaces; flowers axillary; fruiting peduncle only 5 to 7 mm. long, 
bearing small bractlets near the top; calyx tube and lobes very hairy without; pod 
2 cm. long, very pubescent. 
Common on hills near Tehuacin, collected by J. N. Rose, August 1, 2, 1901 (no. 
5910), and again in September, 1906 (no. 11256, type); and by C. A. Purpus in 
June, 1903. 
This species differs from all others which I have seen in its very hairy pods. 
Type U. 8. National Herbarium no. 454039. 
Brongniartia parvifolia Rose, sp. nov. 
A low, spreading shrub 15 to 45 em. high; young parts very pubescent; leaflets 19 to 
31, crowded, narrowly elliptical, mucronate, 6 to 10 mm, long, pubescent on both 
sides; stipules in size and shape much as the leaflets; peduncles axillary, solitary, 
about 10 mm. long, pubescent; bracts subtending the calyx ovate, acute, hairy; calyx 
glabrous, 2-lipped, the tube 3 to 4 mm. long; upper lip 2-toothed; lower lip cut into
