536 CONVOLVULACEJi:. Cuscuia. 



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

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

 and enveloped by the corolla. 



Not rare thvou^'li tho western part of the State. The sliorter-flowered variety tYom the cmust at 

 Monterey (Harltcc(j) to Cleai- Luke {Tunry), ami to the Tuohunno in the Siena Nevada (Jlulun- 

 ilcr) : a low plant, ol'tcn only a lew inches high. Tho var. louijiluba, principally near the coiiat in 

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

 EriviioHuin, kc. These extreme anil the numerous intermediate forms are easily recogiiizeil by 

 the delicate white shar|)ly-lobed llowers destitute of tho substumineal scales : lolies of calyx and 

 corolla never overlapiiing. 



* * Capsule more or less conical or pointed. 



3. C. salina, n. «[). Kngelm. {Stems slender: flowere (1^ to 2 J lines long) 

 j)cdicelled in loose cymes, shorter and wider than in tho 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 niostly shorter tlian tlie tube, sometimes 

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

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

 var. abbreviata, & C. Culifornica, var. (?) squamiyera, Engelm. 1. c. 499, 500. 



Saline marshes, on various Cheno|>odiac(!ous j)lant3, especially Salicornia: liay of Sau Francisco, 

 C. irriijld, IloliiuUd; Kclloijii. Also extending to British Columbia (Xv/«.//), and in the inlerior 

 to Arizona and So\ithcrn 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 llowers ; from the latter by the less crowded llowers, with shortor more delicate and 

 open corolla. 



4. C. SUbinclusa, Durand & Ililgard. Stems rather coarse : flowers sessile or 

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

 lines long : calyx-lobes ovate-hmceolate, acutisli, overlapi»ing, much bhorter than 

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

 shorter tlian tube, ovate-lanceohite, acute, minutely crenidate or pa|)illose : antiiers 

 t)Vid, nearly hcssjId; HrulcH narmw, iVingcuj, reaching only to tliu middle of the tiihe: 

 slender atyles longer than the ]»ointed ovary : ca[)sule conical, capped by the with- 

 ered corolla : seeds mostly solitary. 



The most common Californian species, on shrubs or coaree herbs througliout the State, mostly 

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

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

 reildish calyx, readily distinguishes this species. > 



5. C. decora, Choi.sy, Engelm. Stems coarse: flowers (1^ to 2| lines long) 

 pedicelled in loose clusters : lobes of the lieshy calyx acute, as long as the broatlly 

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

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

 large, broadly oval, deeply fringed : cai)sid() ])(»inted, enveloped by the remains of 

 the corolla : seeds about 4. 



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

 extending through a large j)art of Ameiica, ai)parently rare in California. Tho only specimen 

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

 ture of the corolla fleshy, granular-papillose. 



G. C. denticulata, luigelm. Stems caf)illary : llowers small (about a line long), 

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

 corolla included in the rounded-lubcd 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 

 ])ointed ovary : .stigmas very small and hardly capitate : capsule covered by the 

 withered corolla, 1 - 2-seede(i. — Parry in Am. Nat. ix. 348.
