Cuscuta. CONVOLVULACEJ^. 221 



incomplete: styles equalling or shorter than the ovary: capsule surrounded (not covered) 

 by the marcescent corolla, mostly 1-seeded. — Bot. Calif, i. 530. C. subindusa, var. ab- 

 breviata, & C. Californica, var. ? stjuamigera, Engelm. Cusc. 499, 500. — Saline or brackish 

 marshes of the racific coast, on Salicornia, SmecIci, &c., California to Brit. Cokunbia, and 

 eastward to Arizona and Utah. Intermediate between the preceding and following, distin- 

 guished from the former by larger flowers and the presence of infra-stamineal scales ; 

 from the latter by less crowded flowers, more open, and of more delicate texture. 



C. SUbinclusa, Durand & Hilgard. Stems rather coarse : flowers sessile or short- 

 pedicelled, at length in large (half to full an inch thick) and compact clusters, 2| to 3^^ or 4 

 lines long: calyx cupulate, fleshy; its lobes ovate-lanceolate, overlapping, much shorter 

 than the cylindrical tube of the corolla : lobes of the corolla ovate-lanceolate, minutely 

 crenulate, much shorter than the tube : oval anthers nearly sessile : scales narrow, fringed, 

 reaching only to the middle of the tube : slender styles longer than the ovary : capsule 

 capped by the marcescent corolla, mostly 1-seeded. — Jour. Acad. Philad. ser. 2, iii. 42, & 

 Pacif. R. Rep. v. 11; Engelm. Cusc. 500, & Bot. Calif. 1. c. — California, the most common 

 species throughout the State, on shrubs and coarse herbs. The long and narrow tube of 

 the corolla, only partially covered by the thick and mostly reddish calyx, readily distin- 

 guishes this species. 



C. denticulata, Engelm. Low stems capillary: flowers (about a line long) on short 

 pedicels, in small clusters : tube of the broadly campanulate corolla included in the round- 

 lobed denticulate calyx, and as long as its round-ovate lobes : oval anthers on very short 

 filaments : scales reaching to the base of the stamens, denticulate at the rounded tip : 

 styles as long as the ovary : stigmas very small, not much thicker than the style : capsule 

 covered by the marcescent corolla, 1-2-seeded. — Am. Naturalist, ix. 348, & Bot. Calif, i. 

 536. — South-western Utah, in dry soil, on lierbs and low shrubs, Parri/. 

 = = Flowers more pedicelled, in paniculate cymes. 

 a. Acute tips of corolla-lobes inflexed or coniiculate. 



C. decora, Choisy (but name altered). Stems coarse: flowers fleshy and more or less 

 papillose : lobes of tlie calyx triangular, acute ; those of the broadly campanulate corolla 

 ovate-lanceolate, minutely crenulate, spreading : scales large, deeply fringed : capsule 

 enveloped by the remains of the corolla : seeds usually 4. — Engelm. Cusc. 502 ; Gray, 

 Man. ed. 5, 378, & Bot. Calif. 1. c. ; the negative prefix in C. indecora, Choisy, omitted. 

 (U. S. to Brazil.) 



Var. pulcherrima, Engelm. 1. c. The larger form, with coarser stems, and con- 

 spicuous flowers li to 2^ lines long and wide : anthers and stigmas yellow or deep pur- 

 ple. — C. pulcherrima, Scheele in Linn. xxi. 750. C. netiropelala, Engelm. in Am. Jour. Sci. 

 xlv. 75. — Wet prairies, on herbs and low shrubs, principally Lef/uminosrE and Compositce (the 

 largest-flowered forms in brackish soil on the Te.xan coast), Florida and especially in 

 Texas, nortli to Illinois, and west to Arizona and California. (W. Ind., Mex., Brazil.) 



Var. indecora, Engelm. I. c. Stems lower and more slender : flowers smaller, in 

 looser paniculate clusters, often warty ( C. verrucosa, Engelm. in Am. Jour. Sci. I. c. xliii. 

 341, fig. 25) or papillose-hispid (C. hispidula, Engelm. 1. c. xlv. 75). C. indecora, Choisy, 

 Cusc. 182, t. 3, fig. 3, & DC. 1. c. 457. — Texas, &c., first collected by Berlandier. 



C. inflexa, Engelm. Similar to the preceding : flowers of the same structure, but 

 smaller (only a line long), generally 4-merous : corolla deeper, with erect lobes, finally 

 capping the capsule : scales reduced to a few teeth. — Cusc. 502, & Gray, Man. ed. 5. 

 C. Coryli, Engelm. in Am. Jour. Sci. xliii. 337, fig. 7-11. C. umbrosa, Beyrich, in part ; 

 Engelm. in Gray, Man. ed. 1, 351. — Open woods and dry prairies, on shrubs (hazels, &c.) 

 or coarse herbs, S. New England to Arkansas, and Nebraska. 



C. RACKMOSA, Martins, var. Ciiiliana, Engelm. Stems coarse: flowers (1| to 2 lines long) 

 in loose panicles, thin in texture : tube of corolla deeply campanulate, widening upward ; 

 the spreading lobes shorter, acutish : scales large, deeply fringed. — Cusc. 505, & in Bot. 

 Gazette, ii. 09. C. snaveolens, Seringe ; Gay, Fl. Chil. iv. 448. C. cori/mbosa, Choisy, Cusc. 

 180, not R. «&, P. C. Ilassiaca, Pfeiffer in Bot. Zeit. i. 705. — Introduced into California with 

 seeds of Medicago saliva, as also 40 years ago into Euroi)e, whence, after causing much 

 damage for several years, it has now disappeared. (Adv. from Chili.) 

 b. Obtuse lobes of the corolla spreading. 



C. Gronovii, W^illd. Stems coarse, often climbing high : corolla-lobes mostly shorter 

 than the deeply campanulate tube: scales copiously fringed: capsule globose, umbonate.
