494 CONVOLV ULACEZ CONVOLVULUS 
large flowers mostly solitary in the axils of the leaves. Sepals 
nearly equal or the outer largest, bractless or with a pair of bracts 
at their base. Corolla campanulate, or short and open funnelform, 
with more or less 5-angulate or obscurely 5-lobed border, deeply 
plaited down the sinuses in the bud, the plants convolute, com- 
monly straight, sometimes twisted. Stamens inserted on the tube 
of the corolla, included. Style filiform: stigmas two, subulate or 
flat, and from narrowly linear to oval. Capsule globose, 2-celled, 
the cells 2-ovuled and commonly 2-seeded. Embryo with broad 
and foliaceous cotyledons folded and crumpled in the seed. 
* A pair of thin membranaceo-foliaceous bracts close to the calyx, 
and enveloping or partly enveloping it: stigmas from ovate to oval 
or oblong: flowers(in ours)solitary. 
C. Soldanella L. Sp. 159. Glabrous, fleshy: stems low and mostly 
short, creeping or trailing: leaves reniform, entire or obscurely angulate, 
often emarginate, an inch or two wide, long-petioled: bracts roundish, 
obscurely cordate, not longer than the sepals: corolla pink-purple, 1-2 
inches long, short-funnelform: stigmas ovate. Sandy sea-shores, Puget 
Sound to California. Europe &c. 
C. sepium L. Sp. 153. Glabrous or more or less pubescent, freely twin- 
ing: leaves slender-petioled, deltoid-hastate and triangular-sagittate, 2-6 
inches long, acute or acuminate; the basal lobes or auric!es either entire 
or angulate-2-3-lobed : peduncles mostly elongated: bracts cordate-ovate or

C. occidentalis Gray Proc. Am. Acad. xi, 89. Glabrous or minutely 
pubescent: stems freely twining or prostrate: leaves slender-petioled, from 
angulate-cordate to sagittate or the upper hastate: peduncles elongated, 
surpassing the leaf: bracts large and covering the calyx or variously small- 
er and shorter to lanceolate or linear and more or less foliaceous in texture: 
corolla campanulate-funnelform white or pinkish to cream-color, 12-18 liwes 
long: stigmas linear. Dry hills, Oregon and Washington toCalifornia. 
C. nyctagineus Greene Pitt. iii, 327. C. Californicus of Authors as 
to the Oregon plant. Stems slender, 2-10 inches long, herbaceous to the 
ground: leaves roundish-ovate or semicircular in outline, rounded or 
abruptly acute at the apex, with or without a small hastate lobe on each 
side near the abruptly contracted and somewhat cuneately tapering base, 
the blade 1-2 inches long by about as broad, all on slender petioles 4-6, 
inches long: flowers few, all in the axils of the lowest leaves: peduncles 
about an inch long: bracts oval, obtuse or almost truncate, barely equalling 
the obtuse and muncronate sepals: corolla about 2 inches long by 14 
broad, white: stigma oblong-obovate, nearly 2 lines long: fruiting charac- 
ters not observed. Rather common throughout the Willamette Valley and 
southward to the border of California. 
C. polymorphus Greene Pitt. iii, 331. Herbage pale and puberulent: 
stems slender, 2-4 feet long, twining, herbaceous to the base: leaves from 
reniform-hastate to subsagittate, rather prominently and sharply mucron- 
ate, the blade 10-18 lines long, short-petioled: peduncles short, 1-flowered: 
bracts narrowly elliptic, situated a short distance below the calyx and their » 
tips just reaching its base or longer and partly embracing it: sepals ver
