Convolvulus (Calystegia) Californicus Choisy, which is 

 Cahjstegia suhacauUs Hook. &, Arn., has the same narrow (at most 

 oblong-linear) stigmas, with very short or merely trailing stems, ob- 

 scurely if at all hastate and obtuse leaves, and oblong or oval bracts, 

 very similar to the outer sepals and not surpassing them. 



Convolvulus (Calystegia) villosus, the C. n. sp. ? Torr. in 

 Pacif. R. Rep. 4, p. 127, and Calystegia villosa Kellogg in Proc. 

 Calif. Acad. 5, p. 17, is an allied species, usually silvery white with 

 a dense and soft tomentum, trailing or feebly twining, and the leaves 

 varying from reuiform-hastate to sagittate, the bracts oval or ovate, 

 and only equalling the calyx, the corolla cream-color. The following, 

 instead of the calyx-like membranaceo-foliaceous bracts close to the 

 calyx and enveloping it, has a foliaceous pair at some distance be- 

 low. 



Convolvulus luteolus Gray. Aut glaber, aut pubescens, gra- 

 cilis, volubilis ; foliis triangulari-hastatis vel sagittatis, lobis nunc bifidis; 

 pedunculis folio a^quilongis uni- raro bifloris sub flure bracteas 2 line- 

 ares seu lanceolatas folioformes gerentibus ; sepalis rotundatis ; corolla 

 pallide lutea pollicari vel longiore. — Ipomcea sagittcefolia Hook. «fe 

 Arn., Bot. Beechey, jd. 151, licet stigmatibus lineaiibus. Var. ful- 

 CRATUS. Magis pubescens ; flore foliis hastatis vel sagittatis stipato. 

 C. Calif or nicus ToYY. Va,cit R. Rep. 4, p. 127, non Choisy. — Cali- 

 fornia, in various parts of the State, especially in the southern and 

 western portions ; its bracts from one to four lines long, and about the 

 same distance below the calyx. The variety, which often much re- 

 sembles C. villosus, abounds in the foot-hills of the Sierra Nevada, 

 and has bracteal leaves commonly half an inch long. 



CuscuTA salina Engelm. is a new species added to the Califor- 

 nian flora : it includes C. snbinclusa var. abbreriata, and C. Call- 

 fornica var. ? squamigera of Engelmann's monograph. It affects 

 saline soil and Chenopodiaceous plants, especially Saliconiia, and 

 occurs on the coast from San Francisco Bay to British Columbia. 



CIIAM.ESARACHA. Vide Proc. Am. Acad. 10, p. G2. As 

 Mr. Bentham has justly remarked (Gen. PI. 2, p. 891. ined.), tliis is 

 better completely separated from the genus Saracha ; and only three 

 sjiecies are made out, C. Coronoptts, C. sordida, and C. nana. 

 Saracha acutifolia of Miers, .which is not well described, appears to 

 be a Physfdis.
