368 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
This differs from the species in its narrower, thinner leaves, which are 
attenuate at the base, longer petioles, more slender stems, and pubescent 
fruit; from subspecies volcanica in its different leaves, longer petioles, tuber- 
culate fruit, and more slender stems. Type in the herbarium of the Univer- 
sity of California; collected at Culiacan, Sinaloa, Mexico, September 17, 1904, 
Brandegee. 
2c. Mirabilis jalapa lindheimeri Standley, subsp. nov. 
Stems rather slender, glabrous; leaf blades broadly deltoid-ovate to ovate, 
thin, short-acuminate or acute, truncate, rounded, or narrowed at the base, 
the blades always slightly decurrent upon the glabrous, slender petioles, which 
are usually half as long as the blades or longer; involucres in clusters of 
about 3, or sometimes solitary, mostly pediceled; bracts lanceolate-ovate, 
minutely puberulent, not usually ciliolate, the free portion about as long as 
the tube; flowers about 5.5 em. long; limb about 2.5 em. wide, with prominent 
rounded lobes, the tube almost or quite glabrous; stamens about as long as 
the perianth; fruit about 10 mm, long and 5 mm. thick, ovoid, with 5 incon- 
spicuous, broad ribs, not angled, smooth, not tuberculate, pubescent with 
fine, short, soft, yellowish, appressed hairs. 
This can at once be distinguished by its broad leaves. Its pubescent fruit 
Separates it from the species, and its longer petioles and glabrous stem from 
subspecies volcanica. Type in the herbarium of the Missouri Botanical Gar- 
den, collected at New Braunfels, Tex., June, 1846, Lindheimer.

2d. Mirabilis jalapa ciliata Standley, subsp. noy. 
Stems slender, abundantly furnished with fine, soft pubescence which is 
almost villous, the pubescence especially abundant on the voung stems; leaf 
blades ovate, subacuminate, oblique at the base, about 11 cm. long and 6 em. 
wide or less, thin, glabrous above, more or less puberulent below, all con- 
spicuously ciliate along the margins, the hairs soft and tawny; petioles short, 
25 mm. long or less; flowers sessile or short-pediceled: bracts 12 mm. long 
or less, ovate, short-acuminate, ciliolate: flowers about 55 mm. long, their 
tubes rather thick, the limb about 30 mm. broad; fruit (immature) in shape 
like that of M/. jalapa, tuberculate, finely pubescent. 
The most striking characteristic of the plant is found in the ciliate leaves and 
bracts. Type in the herbarium of the Missouri Botanical Garden, collected 
in the Oaxaca Valley, Oaxaca, Mexico, altitude 1,550 meters, October 1, 1894, 
C. L. Smith 791.
