198 BORRAGINACE^. AmsincHa. 



§ 2. Nutlets (not unlike those of Eritrichium § Plagiohothrys) rugose or 

 muricate, dull, ovate-trigonous and somewhat incurved, carinate ventrally down 

 to the short and broad usually somewhat protuberant scar. 



* Nutlets crustaceous, tessellate-rugose : calyx-lobes obtuse. 

 A. tessellata, Gray. Coarsely and strongly hispid, stout, a foot or two high : leaves 

 from linear-lanceolate to oblong, mostly obtuse : tube of the orange-yellow corolla some- 

 what longer than the ferrugineous-hisjjid calyx (about 3 lines long) and much longer than 

 the lobes : nutlets very broadly ovate, with narrowed apex and flattish back, tliickly 

 covered with granulate-warty projections which fit together in age, forming more or less 

 conspicuous transverse lines or wrinkles ; the scar toward tlie middle of the ventral face. 

 — Proc. Am. Acad. & Bot. Cahf. 1. c. A. h/copsoides, Watson, Bot. King, 240, partly. — 

 Dry grounds, California from the Contra-Costa range through the interior to Nevada and 

 S. Utah. Calyx-lobes either narrowly or rather broadly lanceolate. 



# * Nutlets muricate or sharply scabrous, in age sometimes loosely rugose. (Species difficult to 

 discriminate.) 



Hi— Calyx-lobes narrowly linear-lanceolate or linear, acutish, all over hispid and hirsute : leaves 

 linear or lanceolate. 



A. echinata, Gray, 1. c. Stem strict, 2 or 3 feet high : corolla light yellow, about twice 

 the length of the fulvous-hispid calyx, little dilated at the throat ; the limb 2 or 3 lines in 

 diameter : immature nutlets with the strongly convex and carinate back muricate with 

 soft slender prickles and intermediate scabrous points, not rugose. — S. E. California in the 

 ]\Iohave region, Cooper. 



A. intermedia, Fisch. & Meyer, 1. c. A foot or two high, branching: bristles even 

 of the calyx whitish or barely fulvous : leaves from oblong lanceolate to linear: corolla 

 not above 3 lines long, little exceeding the calyx; the small limb hardly at all plaited: 

 nutlets very convex and carinate on the back, inuricate-scabrous and at maturity obliquely 

 more or less rugose. — DC. I.e.; Gray, Bot. Calif. I.e. A. Ii/copsoides, Gray, Proc. Am. 

 Acad. X. 54, in part; and of gardens. Benthamiu li/copsoides, Lindl. (Introd. Nat. Syst.) in 

 Hort. Soc. Loud. 1828, &c., thence becoming ^4. lycopsoides of cultivation, but probably not 

 of Lehm. — California and W. Nevada to the borders of Brit. Columbia; a common and 

 variable species. 



A. spectabilis, Fisch. & Meyer, 1. c. Mostly slender, a span (when depauperate) to 

 afoot high: leaves mostly linear : tube of the bright orange corolla twice or tlirice the 

 length of the linear lobes of the ferrugineous-hispid calyx, nearly half inch long, or some- 

 times shorter; the throat enlarging, and the limb conspicuously plaited in the bud (a third 

 to half inch wide) ; anthers when high protruded from the throat : nutlets granulate-rugose, 

 carinate aiul roundish on the back. — A. spectabilis & A. Dourjiusiana, DC. I.e. — Open 

 ground, California from San Diego to Plumas Co. 



^^ 4_ Calvx loosely enclosing the fruit, more sparsely setose-hispid, greener and soft-herbaceous 

 in texture'; the lobe's lanceolate or ovate-oblong, mostly obtuse, 2 or 3 of the lobes not rarely united. 



A. lycopsoides, Lehm. Loosely branched, soon spreading, sometimes decumbent, 

 sparsely but strongly sctose-liispid, the bristles on the foliage at length with very pustulate 

 base : leaves greener, from lanceolate to ovate, the margins commonly undulate-repand : 

 upper flowers^ mainly bractless : corolla light yellow, about 4 lines long, with tube little 

 or considerably exceeding the calyx ; the throat little enlarged and limb 2 or 3 lines in 

 diameter : anthers short, included : nutlets reticulate-rugose. — Del. Sem. Hamb. 1. c, name 

 only ; DC. Prodr. x. 117 ; Gray, Bot. Calif, i. 524. —Coast of California, from San Simeon 

 Bay northward to Oregon. Passes into 



Var. bracteosa, a smaller-flowered and more decumbent form (corolla 2 or 3 lines 

 long and the limb a line or two broad), with most of the flowers subtended by a foliaccous 

 bract. — Lithospcrmmn b/ropsoides, Lehm. Pug. ii. 28, & in Hook. Fl. ii. 89, therefore properly 

 the original of Amsinckia lycopsoides, Lehm. 1. c. — San Francisco Bay to Puget Sound. 



13. ECHIDIOCARYA, Gray. (ExiSiov, a diminutive viper, and xagvop, 

 nut, the nutlets with the stalk resembling the head and neck of a snake or other 

 reptile.) — Annuals or biennials of two species, with the habit of Eritrichium
