Physalis. SOLANACE^. 233 



* * Stems very short and tufted on a branching rootstock: fruiting calyx hemispherical, open: 

 seiads very flat, smoothish and minutely punctate. 



C. nana, Gray. Seldom a span high, sometimes nearly acaulescent, minutely cinereous 

 with appressed pubescence, not viscid : leaves crowded and large in proportion, oblong- 

 ovate and ovate-lanceolate, mostly acute, entire or undulate, an inch or two long, and with 

 the roundish or cuneate base abruptly contracted into a margined petiole of about equal 

 length : peduncles mostly shorter than the petioles : rotate corolla white or bluish, 7 to 9 

 lines wide. — Saracha ( Ckamcesaracka) nana, Gray, Proc. 1. c. — Sierra Co., California, at 

 about 5,000 feet in the Sierra Nevada, Bolander, Lemmon. 



7. PHTTSALIS, L. Ground Cherry. ((Jjvaalig, a bladder, from the 

 bladdery-iufiated fruiting calyx which characterizes the genus.) — Herbs, chiefly 

 American or of probably American origin ; with entire, toothed, or lobed leaves, 

 very commonly geminate, and solitary or sometimes geminate (rarely ternate) 

 drooping or nodding pedicels ; the flowers small or middle-sized, white, yellow, or 

 violet-purple : berries greenish, red, or yellow, often edible. — Gray, Proc. Am. 

 Acad. X. 62. 



§ 1. Cham^physalis, Gray, 1. c. Young parts sparsely (or on stalks and 

 calyx densely) scurfy-granuliferous, otherwise quite glabrous : some leaves sinu- 

 ate-pinnatifid : corolla flat-rotate : anthers short, yellow : seeds comparatively few 

 and large, thickish and somewhat rugose-tuberculate round the back. (Habit 

 nearly of Chamcesaracha, but fruiting calyx of true Physalis.) 



P. lobata, Torr. Low and small, diffusely branched from a perennial root : leaves ob- 

 long-spatulate or obovate.from repand to sinuate-pinnatifid (an inch or two long), the base 

 cuneately tapering into a margined petiole : pedicels commonly geminate, longer than the 

 flower: corolla violet (probably never "yellow "), 6 to 9 lines in diameter, the centre with 

 a 5-6-rayed white-woolly star : globular-inflated fruiting calyx strongly 5-angled, half inch 

 or more long; with short bluntish teeth. — Ann. Lye. N. Y. i. 226 (1826) & Bot. Mex. 

 Bound. 152. P. Sabeana, Buckley in Proc. Acad. Philad. 1861. Solanum luteoUflorum, 

 Dunal in DC. Prodr. 1. c. 64, at least as to var. suhintegri/olium. — Plains, Texas to Colorado 

 and "W. Arizona. 



§2. Physalis proper. Not granulose-scurfy : leaves never pinnatifid: corolla 

 mostly rotately spreading from a somewhat campanulate throat or base : seeds 

 with a thin and even margin. 



P. Alkekengi, L., the Winter Cherry of the south of Europe, with white 6-lobed corolla 

 and a red berry in a calyx which turns red also, and 



P. Peruviana, L., the Cape Gooseberry, with greenish-yellow corolla spotted by a brown- 

 purple star in the centre, and a yellow berry, — both perennial-rooted species, — were intro- 

 duced into cultivation several years ago, for their esculent fruit, under the name of 

 Strawberry Tomato. But they have now mainly disappeared. 



P. Carpentekii, Riddell, Cat. FI. Ludov. (N. O. Med. & Surg. Jour. viii. 758, 1852, name 

 only), referred to Withania Morisoni, in Bot. Gazette, iil. 11, is some adventitious Athencea. 



* Corolla pure white or tinged with blue, wholly destitute of any dark centre, tomentose at the 

 throat, proportionally large, widely rotate, with border almost entire : pubescence simple : fruit- 

 ing calyx ovate-globose. 



P. grandiflora, Hook. Annual, with stout erect stem 2 feet or more high, viscid-pu- 

 bescent and young parts villous with some long and slender viscid hairs : leaves oblong- 

 ovate or lanceolate-ovate, acute or acuminate, mostly entire: pedicels often in threes, 

 shorter than the flower : calyx-lobes lanceolate : corolla often an inch and a half in diam- 

 eter: anthers yellow, commonly with a tinge of violet: fruiting calyx less than an inch 

 long, well filled and distended by the berry, the angles therefore obsolete, and the summit 

 open. — Fl. ii. 90; Gray, Man., & Proc. Am. Acad. x. 63, 381. — S. shore of Lake Superior 

 to the Saskatchewan district, springing up in new clearings. Connects with Chama:saracha
