536 CONVOLVULACE^E. Cuscuta. 



of the corolla slender, longer than the tube or even twice as long : filaments and 

 anthers more slender : styles much longer than the ovary : capsule mostly 1 -seeded 

 and enveloped by the corolla. 



Not rare through the western part of the State. The shorter-flowered variety from the coast at 

 Monterey (Hartweg) to Clear Lake (Torrey), and to the Tuolumne in the Sierra Nevada (Bolan- 

 der) : a low plant, often only a few inches high. The var. lougiloba, principally near the coast in 

 the southern part of the State, Santa Barbara to San Diego and into Arizona, in arid localities, on 

 Eriogonum, &c. These extreme and the numerous intermediate forms are easily recognized by 

 the delicate white sharply-lobed flowers destitute of the substamineal scales : lobes of calyx and 

 corolla never overlapping. 



* * Capsule more or less conical or pointed. 



3. C. salina, n. sp. Engelm. Stems slender : flowers (1| to 2| lines long) 

 pedicelled in loose cymes, shorter and wider than in the next : lobes of the calyx 

 ovate-lanceolate, acute, as long as the similar but mostly broader and overlapping 

 denticulate lobes and as the shallow campanulate tube of the corolla : filaments about 

 as long as the oval anthers : fringed scales mostly shorter than the tube, sometimes 

 incomplete : styles as long as or shorter than the pointed ovary ; capsule conical, 

 surrounded (not covered) by the withered corolla, mostly 1 -seeded. C. subinclusa, 

 var. abbreviata, & C. Calif ornica, var. (?) squamigera, Engelm. 1. c. 499, 500. 



Saline marshes, on various Chenopodiaceous plants, especially Salicornia: Bay of San Francisco, 

 C. Wright, Bolander, KeUogg. Also extending to British C'olumbia (Lyall), and in the interior 

 to Arizona and Southern Utah. In many respects intermediate between the preceding and the 

 following species ; but distinguished from the former by the presence of infrastamineal scales and 

 the larger flowers ; from the latter by the less crowded flowers, with shorter more delicate and 

 open corolla. 



4. C. subinclusa, Durand & Hilgard. Stems rather coarse : flowers sessile or 

 short-pedicelled, at length in large (half-inch or inch thick) clusters, 2| to 3^ or 4 

 lines long : calyx-lobes ovate-lanceolate, acutish, overlapping, much shorter than 

 the cylindrical at last urn-shaped tube of the corolla : lobes of the corolla much 

 shorter than tube, ovate-lanceolate, acute, minutely crenulate or papillose : anthers 

 oval, nearly sessile : scales narrow, fringed, reaching only to the middle of the tube : 

 slender styles longer than the pointed ovary : capsule conical, capped by the with- 

 ered corolla : seeds mostly solitary. 



The most common Californian species, on shrubs or coarse herbs throughout the State, mostly 

 in the mountains, the coast ranges as well as the Sierra Nevada, but also along the coast. The 

 long and narrow tube of the corolla, only partially covered by the thick and fleshy and usually 

 reddish calyx, readily distinguishes this species. 



5. C. decora, Choisy, Engelm. Stems coarse: flowers (1| to 2-| lines long) 

 pedicelled in loose clusters : lobes of the fleshy calyx acute, as long as the broadly 

 campanulate tube of the corolla : lobes of the latter as long as its tube, ovate-lance- 

 olate, minutely papillose-crenate, spreading and with acute inflexed tips : scales 

 large, broadly oval, deeply fringed : capsule pointed, enveloped by the remains of 

 the corolla : seeds about 4. 



Near Clear Lake, Bolander ; on a Senecio. A variable species of the southern Atlantic States, 

 extending through a large part of America, apparently rare in California. The only specimen 

 seen belongs to the large-flowered form, which often has deep purple anthers and stigmas. Tex- 

 ture of the corolla fleshy, granular-papillose. 



6. C. denticulata, Engelm. Stems capillary : flowers small (about a line long), 

 short-pedicelled in small umbel-like clusters : tube of the broadly campanulate 

 corolla included in the rounded-lobed and denticulate calyx, and as long as its 

 round-ovate spreading lobes : anthers oval, on very short filaments : scales reaching 

 to the base of the stamens, denticulate at the rounded tip : styles as long as the 

 pointed ovary : stigmas very small and hardly capitate : capsule covered by the 

 withered corolla, 1 2-seeded. Parry in Am. lS r at. ix. 348. 



Southwestern Utah, Parry. To be looked for in adjacent parts of California.
