1. P. barbadensis J acq. 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-
