198 BORRAGINACE^. Amsinckia. 



2. Nutlets (not unlike those of Eritrichium Plagiobothrys} 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-hisp'id calyx (about 3 lines long) and much longer than 

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

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

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

 Proc. Am. Acad. & Bot. Calif. 1. c. A. lycopsoides, 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.) 



-1 '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 

 Mohave 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, muricate-scabrous and at maturity obliquely 

 more or less rugose. DC. I.e.; Gray, Bot. Calif. I.e. A. lycopsoides, Gray, Proc. Am. 

 Acad. x. 54, in part; and of gardens. Bcnthamia lycopsoides, Lindl. (Introd. Nat. Syst.) in 

 Hort. Soc. Lond. 1828, &c., thence becoming A. 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 

 a foot high : leaves mostly linear : tube of the bright orange corolla twice or thrice 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 and roundish on the back. A. spectabilis & A. Donylasiana, DC. I.e. Open 

 ground, California from San Diego to Plumas Co. 



^ -i Calvx looselv enclosing the fruit, more sparsely setose-hispid, greener and soft-herbaceous 

 in texture"; the lobes 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 setose-hispid, 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 foliaceous 

 bract. IMospprnmm lycopsoides, 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. ('E/t&oi', a diminutive viper, and XO.QVOV, 

 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
