8c, Wedelia incarnata nudata Standley, subsp, nov. 
Perennial from a thick, woody root: stems slender, with scattered, short, soft, 
more or less viscid hairs; internodes long, especially the upper ones; leaf blades 
oval or elliptical, 26 mm. long and 14 mm. wide or less, obtuse, ‘ather densely 
puberulent on both surfaces, rounded or oblique at the base; the upper blades 
much smaller, more acute, and with shorter petioles; petioles one-half as long 
as the blades or shorter; peduncles 10 mm. or less in length; bracts 4 mm. 
long or less, elliptical, acutish; flowers 6 min, or less in length, the stamens 
included: fruit straw-colored, 3 mm. long, with a prominent ventral nerve, the 
laternl ones faint or wanting, the wings with 2 or 3 low, rather obtuse, incurved 
teeth. 
Nearest subspecies villosa, but its stems less pubescent, the internodes longer, 
and the stem less leafy above, the flowers and leaves smaller. Type in the 
herbarium of the University of California, collected in Coyote Canyon, western 
border of the Colorado Desert, in the Lower Sonoran Zone, at an altitude of 
about 1,540 meters, 1902, Hall 2799.

The following should probably be placed here, although they have rather 
larger leaves and fruit and their flowers are slightly larger. In general ap- 
pearance, habits, etc., they resemble most this variety.

Perennial herbs, glabrous or pubescent, with the branches of the stem and 
inflorescence opposite or alternate; leaves opposite, rather fleshy, entire, petioled 
or sessile; flowers 1 to 5 in each involucre, white, pink, purplish red, or crimson, 
surrounded by a gamophyllous, 5-lobed involucre which is enlarged and mem- 
branous in fruit; perianth campanulate or infundibuliform, often oblique, 
with an erect or spreading limb; stamens 2 to 5, unequal, filaments very slen- 
der, united at the base; fruit club-shaped, 5-angled or 5-ribbed, pubescent or 
glabrous. 
The genus was based upon a plant which was later named Allionia violacea 
L. Vitmania and Oxybaphus were founded on A. viscosa ; Calyxhymenia upon 
A, glabrifolia; and Calymenia upon six species, all true Allionias, without the 
designation of any one of them as the type.
