524 BORRAGINACE.E. Amsinclcia. 



§ 1. JVutlets broadly ovate-triangular, somewhat incurved, narrowed at the apex, con- 

 vex and someivhat ridged on the back, dull, roughened-granulate, rugose, or 

 muricate ; ventral angle acute and prominent down to the rather broad scar. 

 Hz Nutlets beset with slender prickly p>rojections, 



1. A. echinata, Gray, 1. c. Erect, 3 feet high : leaves lanceolate or broadly- 

 linear : corulla slender, apparently light yellow, 3 or 4 lines long, not broadened at 

 the tliroat, twice the length of the yellowish-hispid calyx : anthers borne in the 

 throat, oval-oblong : nutlets thickly armed with long and narrow rather soft spiny 

 projections, and between these sharp granulate points, not rugose. 



Sandy plains, west of Fort Mohave, Cooper. The nutlets are peculiar ; otherwise the species 

 resembles some forms of the next. 



* * Nutlets granulate-roughened or rugose, the muricate points very short if any, the 

 back convex or at length keeled or ridged. 



2. A. spectabilis, Fischer & Meyer, 1. c. Erect, slender, a span (when depau- 

 perate) to a foot high : leaves mostly linear : tube of the bright orange-yellow corolla 

 twice or thrice the length of the linear lobes of the rusty or reddisli-yellow-hispid 

 calyx, nearly half an inch long ; the throat enlarging, and the expanded limb a 

 third to half an inch in diameter : anthers oblong- linear, when high protruding from 

 the throat : nutlets granulate-rugose, roundish on the back. — A. Douglasiana, A. 

 DC. Prodr. x. 118. 



Open ground, throughout the southern and western part of the State, and as far northeast as 

 Plumas Co. The corolla lias 5 minute bearded tufts in jilace of crests in the thioat, when the 

 stamens are inserted low down the tube ; these not found when the anthers are borne in the 

 throat, which is more plaited than in the other si^ecies. 



3. A. intermedia, Fischer & INIeyer, 1. c. Erect, usually a foot or two high : 

 the bristles even of the calyx whitish or merely yellowish : leaves linear or only the 

 lower lanceolate : corolla bright yellow, 3 or 4 lines long ; its tube a little surpass- 

 ing the narrow-linear calyx-lobes ; the limb barely 2 or 3 lines in diameter : anthers 

 oblong, high or sometimes low on the tube : nutlets not half the length of the 

 narrow calyx-lobes. — A. lycopsoides, partly, of authors, & Proc. Am. Acad. 1. c. 



Dry open groimds, on the eastern borders of the State (Carson City, Andersmi) and common in 

 the interior country to Utah, Idaho, and Oregon. Also near the coast in Sonoma Co., &c. ; on 

 the sea-shore perhaps passing into the next species. 



4. A. lycopsoides, Lehm. More branching and diffuse in age : leaves mostly 

 lanceolate, or even oblong, greener, and the sparse bristles with conspicuous pustu- 

 late base : lower part of the at length lax spikes commonly leafy-bracted : corolla 

 light yellow, 3 lines long or less ; the tube equalling or hardly surpassing the lan- 

 ceolate calyx-lobes, which are hardly twice the length of the nutlets : anthers short. 

 — Del. Sem. Hort. Hamb. 1831, 7 ; Gray, 1. c. in part. Lithospermum lycoptsoides, 

 Lehm. Pug. PI. ii. 28, & Hook. Fl. ii. 89. 



On the coast, San Francisco Bay to Puget Sound. Limb of the corolla a line or two broad. 



* =it * Ntitlets nearly flat on the back, not keeled, coarsely granulate. 



5. A. tessellata, Gray. About a foot high, rather stout, coarsely hispid, the 

 bristles of the calyx rusty-reddish or paler : corolla orange-yellow, 3 or 4 lines long ; 

 the throat plaited ; the tube rather longer than the lanceolate obtuse calyx-lobes : 

 anthers oblong : nutlets broadly ovate, obscurely ridged on the flattened back, 

 thickly covered with truncate warty granulations, which are compacted in more or 

 less wavy transverse lines (so as to appear rugose), closely fitting like the blocks of 

 a pavement. — Proc. Am. Acad. x. 54. 



Dry or arid grounds, from Tejon (Xantus), and the mountains north of Monte Diablo {Brewer), 

 to the eastern side of the Sierra Nevada {Anderson, Lcmmon), and through Nevada {Watson, &c.) 

 to Southern Utah, Parry.
