 form or funnelform. 5. LYCIUM. 



1. PHYSALIS L. Herbs. Leaf -blades entire or sinuate. Flowers axil- 

 lary, nodding, mostly solitary. Calyx bladder-like at maturity, with the lobes

1. P. barbadensis Jacq. Stems generally pubescent and viscid, stout, acutely 

 3-4-angled: leaf -blades 3-6 cm. long, heart-shaped, acute or generally abruptly 

 acuminate, sharply repand-dentate, pubescent with short hairs: peduncles 3-4 

 mm. long, at maturity sometimes 2 cm. long: calyx generally densely viscid- 

 hirsute; lobes lanceolate, acuminate, but not subulate-tipped: corolla 5-10 mm. 

 in diameter: anthers generally purplish: fruiting calyx 2.5-3 cm. long, attenu- 

 ate, almost conic and reticulate, retuse at the base. Pinelands. F. K. (Bah., 

 Cuba, Ant.) 



2. P. angulata L. Stems angular, 0.5-1 m. tall, glabrous: leaf-blades ovate, 

 with a more or less cuneate base, sharply sinuate, with long-acuminate teeth, 

 thin, 4-7 cm. long; nerves not prominent; petioles slender, 2-4 cm. long: 

 peduncles slender, 2-3 cm. long, erect, often reflexed at maturity, but seldom 

 exceeding the fruiting calyx in length: calyx glabrous; lobes triangular to 

 lanceolate, generally shorter than the tube: corolla 5-10 cm. in diameter: 

 anthers more or less purplish- tinged : fruiting calyx about 3 cm. long, ovoid, 

 not prominently 5-10-angled, sometimes purple-nerved and at length nearly 

 filled with the yellow berry. Hammocks. F. K. (Ber., Bah., Cuba, Ant.) 



3. P. viscosa L. Stems from slender horizontal rootstocks, slender, creeping, 

 cinereous with dense stellate pubescence or in age rarely glabrate: leaf -blades 

 elliptic, oval, or ovate, obtuse, thinnish, entire or undulate, sometimes cordate 

 at the base (spatulate or oblong, with a tapering base, in P. viscosa maritima) : 

 peduncles 1-2 cm. long: calyx stellate-pubescent; lobes triangular, generally 

 shorter than the tube: corolla greenish-yellow with a darker center, 1.5-2 cm. 

 in diameter : fruiting calyx 2-3 cm. long, rounded ovoid, scarcely sunken at the 

 base: berry orange or yellow. Pinelands and coastal sand-dunes. F. K. 



4. P. Elliottii Kunze. Stems from slender horizontal rootstocks, with the 

 foliage glabrous to the flowers, or sparingly stellate-pubescent when young, 

 ascending, branched, slightly stellate or glabrate, 3-5 dm. tall: leaf -blades very 

 thin and veiny, oblong, spatulate, broadly oblanceolate, or in luxuriant speci-
