STANDLEY—ALLIONTACEAE OF THE UNITED STATES. 371 
Mexico: Parras, Coahuila, 1905, Purpus 1056; near Chihuahua, 1885, 
Pringle 101; Saltillo, 1848, Gregg 88; Buena Vista, 1547, Gregg 355, 
New Mexico; Delaware Creek, 1893, Nealley 12. 
CALIFORNIA: Marie Mountains, Colorado Desert, eastern Riverside County, 
1906, BE. BE. Schellenger. 
The California specimen, received at a late day from Prof. H. M. Hall, of the 
University of California, extends the range of the species considerably to the 
northwest, 
Attached to his no. 355 in the herbarium of the Missouri Botanical Garden is 
the following interesting note by Doctor Gregg regarding this plant: “ Yerba 
santa (or yerba de la rabia) ; the root in a decoction is used for cholera, fevers, 
ete. Said to have acquired the name of yerba santa (holy herb) in 1814 on ac- 
count of its wonderful virtues in curing a plague of that year.” 
4a. Acleisanthes longiflora hirtella Standley, subsp. nov. 
Stems hirtellous throughout; leaves like those of the species, but broader 
and not attenuate, more or less puberulent on both surfaces, thick; otherwise 
like the species; “flowers white,” the perianth more puberulent than in the 
species. ; 
Type in the herbarium of the Missouri Botanical Garden collected near 
Saltillo, Coahuila, Mexico, September 20, 1848, Gregg 463. Gregg’s 725 from 
“highlands near Patos” is probably the same; it has, however, very small 
leaves, and the collector says of it “ flowers scarlet; a small shrub.” 
5. Acleisanthes crassifolia A. Gray, Am. Journ. Sci. II. 15: 260, 1853. 
Type locality, “ High prairies of San Felipe Creek, W. Texas.” 
Specimens exramined: 
Texas: Wright 599, type collection; Van Horn, 1900, Eygert. 
6. Acleisanthes obtusa (Choisy) Standley. 
Nyctaginia obtusa Choisy in DC, Prod, 13°: 429, 1849. 
Acleisanthes berlandiert A. Gray, Am. Journ. Sei. II. 15: 260, 1853. 
Doctor Gray in his description of A. berlandiecri suspected that his species 
might be the same as the plant published by Choisy in the genus Nyctaginia. 
I have seen a specimen of the type collection of NV. obtusa in the Engelmann 
Herbarium which leaves no room for doubt regarding the matter. 
Specimens examined: 
Texas: Berlandier 2007, type collection; San Fernando (Creek?), 18385, 
Berlandier 3044; between Rio Frio and Nueces, Berlandier 3208; 
Corpus Christi, 1860; Eagle Pass, Havard ; Uvalde, 1880, Palmer 1117; 
Mexican Boundary Survey 1125; Roma, 1889, Nealley 228; San An- 
tonio, 1882, Letterman 124; Dilley, 1905, Reverchon; Laredo, 1882, 
Letterman. 
7. Acleisanthes greggii Standley, sp. nov. 
Perennial; stems stout, lignescent, dichotomously much-branched, glabrous 
below, minutely puberulent above and on the younger branches; internodes 
short, 1 to 2 cm. long; leaf blades ovate, cordate or truncate at the base, very 
thick, 15 mm. long or usually less, glabrous, paler below, rather obtuse ; 
petioles stout, one-half as long as the blades; flowers sessile, about 3 ecm. 
long, tubes slender, limb 15 mm. wide, ‘white and pinkish purple within; ” 
stamens 5, much exserted; flowers single or sometimes 2 or 3 together, each 
subtended by 2 or 3 thick, subulate bracts; fruit in the type not fully devel- 
oped, but 5 mm. long and strongly 5-angled.
