§ 1. Nutiels broadly ovate-tnam/tdar, somewhat incurved, narrowed at the apex, con- 

 vex and somewhat ridged on the back, dull, roucjhened-c/ranulate, rucjose, or 

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

1. A. echinata, <iiiiy, 1. c. Kivct, 3 ibct liij,'li : loaves luiiccoluto or broadly 

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

 the throat, twice the length of the yellowish-liispid calyx: anthers borne in the 

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

 projections, antl between these sharp granulate i)oints, not rugose. 



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

 resembles some forms of the next. 



* * Nutlets granulatc-rutif/hened 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 tlie length of the linear lobes of the rusty or reddish-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 protrmling from 

 the thmat : nuthits grunulute-rugosu, roundish on tiio buck. — A. J)oiiglasiana, A. 

 DC. I'rodr. X. 1 1 8. 



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

 Plumas Co. The corolla has 5 minute bearded tufts in place of crests in the throat, 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 species. 



3. A. intermedia, Fischer & IMeyer, 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 : antiiers 

 oblong, high or scjmetimes low on the tube : nutlets not half the lengtli of the 

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



Dry open giounds, on tlie eastern boideis of tlio State (Carson City, Anderson) and common in 

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

 the sea-shore j)erhai)s passing into the next species. 



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

 lanceolate, or even obh)ng, greener, and the bjiarse bristles with conspicuous pustu- 

 late base : lower jiart of tlio at length lax spikes commonly loal'y-bracted : corolla 

 light yellow, 3 lines long itr lea.s ; tlio tube ocpiidling or hardly HurpUMMing the lan- 

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

On the coast, San Franci.sco Bay to Paget Sound. limb of the corolla a line or two broad. 



* * * Nutlets nearly flat on the back, not keeled, coarsely granulate. 



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

 bristles of the calyx rusty-reddish or ])aler : 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 jlattened back, 

 thickly covered witli truncate warty granulations, which are conipactcil in more or 

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

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



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