PHYSALIS 



root : flowering branches mostly short and leafy : leaves commonly oblong 

 to obovate, obtuse, rarely ovate and acute, entire, half inch to 2 inches 

 long, more or less acute or narrowed at base, or the lower and larger ones 

 rounded, on short petioles ; flowers in short-peduncled few-several -flowered 

 umbels : calyx-lobes about 2 lines long in flower, ovate, obtuse : corolla 8-10 

 lines broad, blue to white, angulately 5-lobed, widely rotate: anthers ob- 

 tuse, the cells opening by a short vertical slit at the apex, which extends 

 downward to the base : berries purple, the base covered by the appressed 

 moderately enlarged calyx. On stony hillsides, southern Oregon to Calif. 



S. sisymbrifolium Lam. Dunal in DC. Prodr. xiii, 49. Villous-pu - 

 bescent with simple more or less glandular and viscid hairs, mixed on the 

 leaves with some few-rayed stellate ones ; much armed even to the calyx 

 with long subulate straight prickles: stem stout, 2-3 feet high, branching: 

 leaves deeply pinnatifid and the oblong lobes sinuate or even again some- 

 what pinnatifid: flowers several or numerous, in terminal or soon lateral 

 pedunculate racemes; lobes of the 5-parted calyx lanceolate, becoming 

 ovate-lanceolate and at length loosely and completely or incompletely cov- 

 ering the globose red berry : corolla light blue or white, 1-2 inches' broad,

2 PHYSALIS L. Gen. n. 250. (ground cherry) 

 Annual or perennial herbs with entire or sinuately- toothed 

 leaves and yellow or white flowers on axillary and solitary ped- 

 uncles. Calyx campanulate, 5-toothed, in fruit enlarged and 

 bladders-inflated, membranaceous, 5-angled, or prominently 10- 

 ribbed and reticulated, wholly inclosing the pulpy berry, its teeth 

 mostly connivent. Corolla rotate or rotate-campanulate, plicate in 

 the bud, 5-angulate or obscurely 5-lobed. Stamens inserted near 

 the base of the corolla : anthers oblong, longer than their filaments, 

 not connivent, opening by a longitudinal slit. Style slender, some- 

 what bent ; stigma 2-cleft. Seeds numerous, kidney-shaped, flat- 

 tened, with a thin edge, finely pitted. 



P. ixocarpa Brot. Hornem. Hofn. Supp. 26. A little hairy or pu- 

 bescent when young: stem erect, much branched, 1-2 feet high from an 

 annual root : leaves ovate or oblong, repand or sinuate-toothed or entire, 

 1-2 inches long or rarely longer, on long and slender petioles : pedicels only 

 1-3 lines long : calyx-lobes short, broadly triangular, shorter than the tube : 

 corolla bright yellow with purple throat; 6-12 lines broad : fruiting calyx 

 rounded-ovoid, obscurely 10-angled, often purple-veined, at last often filled 

 with the berry which sometimes bursts it. Native of Mexico : escaped 

 from cultivation in eastern Washington. 



P. pruinosus L. Sp. 184. Villous or pubescent with simple viscid 

 hairs : stem stout, from an annual root, 1-2 feet high, with at length wide- 

 ly spreading branches, obtusely angled: leaves firm, 2-5 inches long, ovate- 

 cordate, generally very oblique at the base and deeply sinuate-toothed 

 with broad and often obtuse teeth : peduncles 1-2 lines long, in fruit about 

 6 lines long: calyx villous or viscid, the lobes as long as the tube, narrow- 

 but not subulate-tipped: corolla 2-5 lines broad, dull yellow with purplish-
