988 SOLANACEAE 
4. CHAMAESARACHA A. Gray. 
Perennial herbs, with entire or pinnatifid leaf-blades, these decurrent on the petiole. 
Peduncles solitary, or in clusters of 2-4 from the axils of the leaves. Calyx campanu- 
late, 5-lobed, somewhat enlarged at maturity, but not bladdery-inflated, close-fitting to the 
berry, thin, neither angled nor ribbed, and faintly, if at all, veiny, open at the mouth, 
not exceeding the berry. Corolla rotate, white or ochroleucous, often tinged with purple : 
limb plicate. Stamens adnate to the base of the corolla. Anthers oblong, opening by 
longitudinal slits. Style and stigma as in Physalis. Seeds reniform, flattened, rugose- 
favose or punctate. The plants flower in the summer. 
Foliage puberulent and hirsute: pubescence dense. : 1. C. conioides. 
Foliage puberulent or stellate-pubescent, the calyx only sometimes hirsute: pubescence sparse. 
2. C. Coronopus. 
1. Chamaesaracha conioides (Moric.) Britton. Foliage cinereous-puberulent with 
short branched somewhat glutinous or viscid hairs, generally also viscidly hirsute or villous 
with long and branched hairs, especially on the calyx. Stems much branched from the 
base, at first upright, at length spreading: leaf-blades oblanceolate to obovate-rhombic, 
generally acutish and tapering into short petioles, generally deeply lobed, but varying 
from nearly entire to pinnatifid : calyx-lobes triangular, generally acutish : corolla about 
lem. in diameter, white or ochroleucous, sometimes violet purplish: berry from 5-8 cm. 
in diameter. 
In dry clayey soil, Kansas to California and Mexico. 
2. Chamaesaracha Corónopus (Dunal) A. Gray. Foliage pruinose or stellate- 
pubescent or glabrate. Stems branched from the base and diffuse, obtusely angled : leaf- 
blades linear or lanceolate, tapering at the base, more or less sinuately lobed, occasionally 
subentire, sometimes pinnatifid : calyx stellate-pubescent or sometimes hirsute ; lobes 
triangular, acute: corolla white or ochroleucous, the appendages of the throat often pro- 
tuberant: berry 5-8 mm. in diameter, nearly white. 
In clayey soil, Kansas to Utah, Texas and Mexico. 
5. SOLANUM L. 
Annual or perennial often spiny herbs or shrubs, or sometimes vines. Leaves alter- 
nate: blades entire, toothed, pinnatifid or variously lobed. Flowers in cymes, racemes, 
panicles or umbel-like clusters. Calyx varying from campanulate to rotate, sometimes 
accrescent : lobes usually 5. Corolla white, yellow, blue or purple, rotate: tube very 
short: limb 5-angled or 5-lobed, plaited. Stamens 5, adnate to near the throat of the 
corolla-tube. Anthers narrow, converging or united into a cone : sacs opening by terminal 
pores, slits or sometimes lengthwise. Ovary mostly 2-celled. Berries subglobose or oval, 
seated in the calyxes or rarely enclosed by them. Seeds flattened.
