Fl. Serres, xiv. t. Ull ; Brew. & Wats. Bot. Calif, i. 22. —Dry hills, California, from San 

 Diego, San Bernardino, &c., to Butte Co. 



D.* Harf ordii, Kellogg. Low or arborescent shrub ; leaves oval, or broadly oblong, 

 usually very obtuse, and mucronate at apex (rarely ovate-lanceolate and acute), thick but 

 somewhat less harsh than in the preceding; margins entire or inconspicuously crenulate, 

 never so scabrous-ciliolate as often in the last : axillary buds at certain stage in their 

 development rigid and almost thorn-like. — Proc. Calif. Acad. Sci. v. 102. D. JlexiUs, 

 Greene, Bull. Torr. Club, xiii. 216. D. rlgida, var. Harf ordii, K. Brandegee, Zoe, iv. 83. — 

 Islands off coast of S. California. Dr. Kellogg's species as originally collected on Santa 

 Rosa Isl. is said to be a low shrub, but the foliage shows no constant or satisfactory 

 differences from the arborescent D. flexilis, Greene, of Santa Cruz Isl. Essentially the 

 same plant has been collected upon Santa Catalina Isl., Brandef/ee. All these insular forms 

 are unsatisfactorily separable from each other and none too definitely distinguished from 

 broad-leaved forms of the mainland, such as Hartweg's 1641. (See T. S. Brandegee, 

 Zoe, i. 46.) 



7. ROMNfiYA, Harv. (The astronomer, 7\ Romriey Rohinson, friend of 

 Dr. Coulter, the discoverer of the plant.) — Lond. Jour. Bot. iv. 74, t. 3 (stigmas 

 not well given) ; Torr. Bot. Mex. Bound. 31. — Single species, large- and white- 

 flowered, with colorless bitter juice. 



R. Coulteri, Harv. 1. c. 75. Herbaceous stems 3 to 8 feet liigh from a soft woody base, 

 branching, leafy to the top, glabrous, glaucescent : leaves of firm texture, pinnately parted 

 or divided, petioled ; divisions or leaflets 3 to 9, cuneate-oblong to lanceolate, sparingly 

 dentate, terminal 3-cleft, margins and rhachis often sparsely ciliate-spinulose : flowers short- 

 peduncled, terminating the branches, delicately fragrant, a few days in anthesis : petals 

 bright white, 2 inches long: capsule inch and a half long. — Brew. &, Wats. Bot. Calif, i. 

 20; W. Kobinson, Garden, xxvi. 400, t. 465. ^ — Plains and ravines, S- California, Ventura 

 Co.2 to San Bernardino, San Diego Co. (and Lower Calif.); first coll. by 21i. Coulter; fl. 

 all summer. 



8. ARGEMONE, Tourn. Prickly Poppy. (Ancient Greek and Latin 

 name of some herb, transferred to this American genus by the herbalists.) 

 — Setose and spinulose-dentate herbs, chiefly annuals, but in hot countries 

 becoming indurated and lignescent below, leafy-stemmed and branching, with 

 orange-yellow and acrid juice, the leaves sinuate or pinnatifid, commonly varie- 

 gated with white. Sepals with cornute tip or appendage below the apex. — Inst. 

 239, t. 151; L. Gen. no. 422.^ — Consists of the following species or forms, 

 which cannot be very definitely characterized. 



A. FRUTicrjSA, Ihiwhev, Jide Gray, PI. Thurb. 306 ; Wats. Proc. Am. Acad. xvii. 318, of 

 Coahuila, Mexico, Thurber, Palmer, is very glaucous, with small and fleshy rigid leaves and 

 sessile sulphur-yellow flowers, and has the branches so completely ligneous-indurated, that it 

 can hardly be joined with A. Mexicana. 



A. GRANDiFLORA, Swect, Brit. Fl. Card. t. 226; Lindl. Bot. Reg. t. 1264; Hook Bot. Mag. 

 t. 3073, of Mexico, said to be ])ereniiial, has white petals of 1^ to 2 inches in length, glabrous 

 and unarmed stems, sepals, and capsule, yet the latter occasionally bears a few s])iniform seta;, 



A. MexicAna, L. Stems, as well as foliage, also sepals and capsule more or less setose- 

 prickly : petals dull or pale yellow or ochroleucous, an inch or less long, nearly sessile or 

 sul)tended by small leaves. — Spec. i. 508 ; Gray, Gen. 111. i. 112, t. 47. — Wa.ste places, com- 

 mon southward and near coast, less so northward. (Nat. from Mex.)
