SOLANACEAE 987 
4-6 cm. and reflexed at maturity: calyx densely stellate ; lobes triangular, generally a 
little shorter than the tube : corolla 1.5-2 cm. in diameter, bright yellow and with a pur- 
plish center, more or less stellate-pubescent without : anthers yellow or tinged with pur- 
ple: fruiting calyx 3-5 em. long, ovoid, acuminate, slightly 5-angled and a little sunken 
at the base. 
In thickets and along streams, Arkansas to California, Texas and Mexico.—A greener, less pubes- 
cent form with more rounded and less toothed leaf-blades is P. mollis cinerdscens (Dunal) A. Gray, and 
another form with small leaves 1-2 em. long and small fruiting calyx is P. mollis parvifolia Rydb. 
30. Physalis viscósa L. Perennial from slender horizontal rootstocks. Stems 
slender, creeping, cinereous with a dense stellate pubescence or in age rarely glabrate: 
leaf-blades elliptic, oval or ovate, obtuse, thinnish, entire or undulate, in the typical South 
American form often cordate at the base, only rarely so in our plant: 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. 
Onsea beaches and in sand near the coast, Virginia to Texas and south to the Argentine Republic. 
—The form with spatulate or oblong leaf-blades tapering into the petiole, is P. viscosa marítima (M. A. 
Curtis) Rydb. 
31. Physalis fuscomaculàta DeRouv. Perennial, greener than the other stellate- 
pubescent species. Stems decumbent or ascending, terete, with decurrent ridges, a little 
pruinose-stellate : leaf-blades 2-4 cm. long, ovate, somewhat oblique at the base, entire or 
repand, the upper often opposite: peduncles 1-3 cm. long, longer than the petioles and 
often as long as the leaves at maturity : calyx pruinose, a little stellate and stellate-ciliate ; 
lobes triangular, shorter than the tube: corolla yellow with a dark spot: fruiting calyx 
subglobose, 10-angled, somewhat sunken at the base. 
A South American species found on or near ballast and in waste places at Mobile, Alabama. 
32. Physalis Ellióttii Kunze. Perennial from slender horizontal rootstocks, the 
foliage glabrous to the flowers, or sparingly stellate-pubescent when young. Stems ascend- 
ing, branched, slightly stellate or glabrate, 3-5 dm. tall: leaf-blades very thin and veiny, 
oblong, spatulate, broadly oblanceolate, or in luxuriant specimens broadly oval, entire or 
wavy-margined, decurrent into a winged petiole: peduncles 2-3 cm. long, slender, erect, 
but reflexed and often 5 cm. long at maturity : calyx generally glabrous except the margin 
which is stellate-ciliate ; lobes triangular: corolla 1.5-2 cm. in diameter, yellow with dark 
center : fruiting calyx generally a little shorter than in the next species. 
On the seacoast, Florida to Texas. 
33. Physalis angustifdlia Nutt. Perennial from slender elongated and creeping 
rootstocks, the foliage often perfectly glabrous except the margins of the calyx-lobes or 
rarely sparsely stellate all over when young. Stems diffusely branched, angled : leaf- 
blades linear or linear-oblanceolate, tapering into the petiole, entire, thickish ; nerves ex- 
cept the midrib, generally obsolete : peduncles 2-3 cm. long, filiform, generally erect, 4-5 
em. long and reflexed at maturity: calyx glabrous, except the stellate-ciliate margins of 
the rounded triangular lobes: corolla about 2 cm. broad, yellow and with purple center : 
anthers yellow : fruiting calyx small, 1.5-2 cm. long, ovate, obscurely angled and scarcely 
sunken at the base. 
On sea beaches or in sand near the coast, Florida to Louisiana. 
3. QUINCULA Raf. 
Perennial herbs, with scurfy-granuliferous foliage and diffuse stems. Leaves alternate : 
blades sinuate to pinnatifid, somewhat fleshy. Peduncles most commonly in pairs from 
the axils of the leaves, sometimes solitary or in clusters of 3-5. Flowers erect during 
anthesis. Calyx campanulate, inflated at maturity, sharply 5-angular and reticulated, 
enclosing the fruit: lobes 5, converging. Corolla flat-rotate, pentagonal in outline, veiny, 
violet or purplish. Anthers opening by longitudinal slits. Seeds comparatively few, reni- 
form, somewhat flattened, thick-margined, rugose-tuberculate. 
1. Quincula lobata (Torr.) Raf. Stems spreading or prostrate, obtusely angled and 
striate, much branched : leaf-blades oblanceolate or spatulate to oblong, sinuately toothed 
or pinnatifid with rounded lobes, or rarely nearly entire, cuneate at the base, tapering into 
margined petioles, thickish and veiny : peduncles 2-5 cm. long, reflexed at maturity : calyx- 
lobes triangular, acute, shorter than the tube: corolla purplish, 2-3 dm. in diameter : an- 
thers yellow, tinged with purple : fruiting calyx about as wide as long, sharply 5-angled, 
sunken at the base. 
On high plains, at the base of the Rocky Mountains, extending from Kansas to California, Texas 
and northern Mexico. Summer.
