SOLANACEAE. 813 



Slits, seeds comparatively few, kidney-shaped, somewhat flattened, with thick 

 margins. [Name unexplained.] A monotypic genus. 



1. Quincula iobata (Torr.) Raf. Purple-flowered Ground-cherry. 

 (I. F. f. 3207.) Perennial, spreading or prostrate; stem obtusely angled and 

 striate, much branched. Leaves oblanceolate or spatulate to oblong, sinuately 

 toothed, or pinnatifid with rounded lobes, or rarely subentire, cuneate at the base, 

 thickish and veiny, tapering into margined petioles; peduncles 2-5 cm. long, in 

 fruit reflexed; calyx-lobes triangular, acute, shorter than the tube; corolla 2-3 cm. 

 in diameter; anthers yellow, tinged with purple; fruiting calyx about as wide as 

 long, sunken at the base. On high plains, Kans. to Cal. and Mex. May-Sept. 



4. LEUCOPHYSALIS Rydberg. 



A tall erect viscid and villous annual, with entire leaves, the blade decurrent 

 on the petiole. Peduncles generally in fascicles of 2-4 in the axils. Calyx cam. 

 panulate, 5-lobed, at first a little inflated, but soon filled by and closely fitted to 

 the berry, thin, neither angled nor ribbed, faintly veiny. Corolla rotate, white, 

 sometimes tinged with purple and generally creamy or yellow in the center, the 

 limb plicate. Stamens inserted near the base of the corolla; filaments long and 

 slender; anthers oblong, opening by longitudinal slits. Style and stigma as in 

 Physalis. Seeds kidney-shaped, flattened, punctate. [Greek, white Physalis.} 

 A monotypic genus. 



1. Leucophysalis grandifidra (Hook.) Rydberg. Large White-flowered 

 Ground-cherry. (I. F. f. 3208.) Erect, 3-9 dm. high; stem more or less vil- 

 lous. Leaves 1-2 dm. long, ovate to lanceolate-ovate, generally acute and entire, 

 more or less villous and viscid; peduncles several from each axil, villous; calyx- 

 lobes lanceolate, equalling the tube; corolla 3-4 cm. in diameter, rotate; anthers 

 short, yellow, often tinged with purple; fruiting calyx ovoid, early filled by the 

 berry. Vt. to Saskatch. and Minn. May-July. 



5. CHAMAESARACHA A. Gray. 



Perennials, the leaf-blade decurrent on the petiole. Peduncles solitary, or in 

 fascicles of 2-4 in the axils. Calyx campanulate, 5-lobed, in fruit somewhat 

 enlarged, but not bladdery-inflated, close-fitting to the berry, thin, not angled nor 

 ribbed, and faintly if at all veiny, open at the mouth, not exceeding the berry. 

 Corolla rotate, white or cream-colored, often tinged with purple, the limb plicate. 

 Stamens inserted near the base of the corolla; filaments long and slender; anthers 

 oblong, opening by longitudinal slits; style and stigma as in Physalis. Seeds 



I kidney-shaped, flattened, rugose-fa vose or punctate. [Ground- Saracha, the latter 

 a genus named in honor of Isidore Saracha, a Spanish Benedictine botanist.] An 



I American genus, of half a dozen species. 



; Pubescence dense, puberulent and hirsute. 1. C. contoides. 



1 Pubescence sparse, puberulent or stellate, hirsute (if at all) only on the calyx. 



2. C. Coronopus. 



1. Chamaesaracha conioides (Moricand) Britton. Hairy Chamaesar- 

 ACHA. (I. F. f. 3209.) Much branched, at first upright, at length spreading, cine- 



' reous-puberulent with short branched somewhat glutinous or viscid hairs, gen- 

 erally also viscidly hirsute or villous with long and branched hairs, especially on 

 I the calyx; leaves oblanceolate to obovate-rhombic, usually acutish, subentire to 

 I pinnatifid; calyx-lobes triangular, generally acutish; corolla about 12 mm. in 

 I diameter, white or ochroleucous, or sometimes violet-purplish; berry 5-8 mm. in 

 > diameter. In dry clayey soil, Kans. to Cal. and Mex. May-Sept. 



2. Chamaesaracha Coronopus (Dunal) A. Gray. Smoothish Chamae- 

 ! Saracha. (I. F. f. 3210.) Branched and diffuse; stem obtusely angled; pubes- 

 cence on the stem and leaves more or less roughish pruinose or stellate, often 

 scarcely any; on the calyx stellate or sometimes hirsute. Leaves linear or lanceo- 

 late, sinuately lobed, occasionally subentire, sometimes pinnatifid; calyx-lobes 

 triangular, acute; corolla white or ochroleucous, the appendages of the throat 

 often protuberant; berry nearly white. In clayey soil, Kans. to Utah, Cal. and 

 Mex. May-Sept,
