494 CONVOLVULACE^E 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. 359. 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, phort-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 auricles either entire 

 or angulate-2-3-lobed : peduncles mostly elongated : bracts cordate-ovate or 

 somewhat sagittate, commonly acute: corolla broadly funnelform, 2 inches 

 long, white or tinged with rose-color : stigma from ovate to oblong. Along 

 streams, Brit. Columbia to California and across the Continent. 



* * Stigmas linear or oblong-linea 



C. occidentalis Gray Proc. Am. Acad. xi. 89. Glabrous or minutely 

 pubescent: stems freely twining or prostrate: leaves alender-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 liaes 

 long : stigmas linear. Dry hills, Oregon and Washington toCalifornia. 



C. nyctagineus Greene Pitt, iii, 327. C. Calif ornicus 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 1>| 

 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. polymorphous 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 very 

 unequal, the outer often broadly oval and truncate and only half the length
