ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 267 
on both surfaces; rachis as well as pedicels and sepals also densely stellate-pubescent; 
gland between leaflets of lower pair narrow-elongated; pods 6 to 8 cm. long; many- 
jointed, strongly stipitate. 
Collected by C. A. Purpus at San Pablo, near San José del Cabo, Lower California, 
in 1901 (no. 287, type) and by Nelson and Goldman between Miraflores and San 
Bernardino ranch, in Sierra La Laguna, Lower California, January, 1906 (no, 7418), 
Type U.S. National Herbarium no. 470361. 
This species is nearest C. villosus, but has small and differently shaped leaflets, a 
much narrower gland between the leaflets, fewer-flowered inflorescence, and per- 
haps a longer stipe to the pods. 
Cassia macdougaliana Rose, sp. nov. 
A low compact shrub, 30 to 60 em. high; branches puberulent; stipules ovate, 
acute, dry, subpersistent; leaflets usually 3 or 4 pairs, short-oblong, 3 to 5 mm. long, 
mucronately tipped, glabrous above, puberulent beneath, thickish, the veins indis- 
tinct above, somewhat prominent beneath, rachis puberulent, bearing a stipitate 
cup-shaped gland; flowers borne toward the ends of the short branches, axillary, 
solitary; peduncle slender, puberulent; sepals membranaceous, obtuse; petals large, 
deep yellow, pods 3 em. long, flat, nearly glabrous. 
Collected by J. N. Rose in company with Dr. D. T. MacDougal near Tehuaciin, 
Puebla, September 1, 1906 (no. 11253, type) and near the same locality by Rose and 
Hay in August, 1901 (no, 5888). 
Type U. 8. National Herbarium no. 454036. 
This species is nearest C. gregyi/, from northern Mexico, but differs in its shorter, 
less glossy, and less reticulated leaflets. 
Casvia greggit was referred by Bentham to his subgenus Chamaecrista, and it has 
since keen transferred to the genus Chamaecrista, but its relationship is clearly not 
there. 
ANEW SPECIES AND TWO CHANGES OF NAME IN CHAMAECRISTA. 
A careful review of the various species of Chamaecrista in Mexico 
has brought to light one undescribed species and revealed the necessity 
of one change of name and one transfer from Cassia to Chamaecrista. 
Chamaecrista amplistipulata Rose, sp. nov. 
Suffrutescent and branching at base; stems somewhat zigzag, angled, glabrous, 20 
to 30 cm. long; leaves closely set, 4 to 8 cm. long; stipules broadly ovate, tapering 
into a spinescent point, strongly nerved, long-ciliate; leaflets 30 to 40 or even more 
pairs, linear, 3 to 7 mm. long, acute, thickish, strongly 3-nerved below, either gla- 
brous or ciliate; gland cup-shaped, sessile; flower buds acuminate; sepals thin, 
puberulent; petals 12 mm. long; ovary cinereous-pubescent; pod 38 to 4 cm. long, 
slightly hairy. 
Collected by E. W. Nelson near Santa Efigenia, Oaxaca, July 18, 1894 (no, 2850). 
Type U. 8. National Herbarium no, 229222, 
This species belongs in Bentham’s series Coriaccae of Chamaecrista, but it seems 
not very near any species described by him.

In 1768 Miller described in his Dictionary a plant from Vera Cruz, Mexico, col-
