 Fruiting calyx long-acuminate : leaf-blades scarcely ob- 

 lique at the base, cordate, abruptly acuminate. 1. P. barbadcnsis. 

 Fruiting calyx not long-acuminate : leaf-blades very ob- 

 lique. 2. P. floridana.

 Plants perennial, with horizontal rootstocks. 



Plants densely pale-pubescent : calyx stellate-pubescent. 4. P. viscosa. 



Plants glabrous or nearly so : calyx glabrous, except the 



margin. 5. P. angustifolia. 



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, reticulate, retuse at the base. — Pinelands and sandy places, 

 L. keys.— [E. K.]— (Bo/i., Cuba, Ant.) 



2. P. floridana Rydb. Stems diffusely branched, angled, densely villous with 

 long white viscid hairs: leaf -blades roun<]ed. cordate, oblique at the base, 2-5 

 cm. long, coarsely sinuately toothed, obtuse, sparingly viscid-pubescent on both 

 sides: peduncles short, in fruit about 1 cm. long: calyx densely viscid pubes- 

 cent; lobes lanceolate, acuminate: corolla 6-8 mm. in diameter, yellow with 

 purple spots: anthers jHirplish: fruiting calyx 2-2.5 cm. long, 5-angled, deeply 

 retuse at the base. — Hammocks and cultivated grounds, U. keys. 



3. 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, Key West. — [E. K.] — {Ber., Bah., 

 Cuba, Ant.) 



4. 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. — Coastal sand-dunes, U. S. keys. — [E. K.]
