AMSINCKIA 
late, hispid, somewhat connivent over the fruit: nutlets deltoid-ovate in 
outline, half the length of the sepals, sharply muricate over the back, 
which is hardly convex except by a slight dorsal ridge, and with distinct 
and thickish but acutish lateral angles these muricate-papillose like the 
back, attached for 24 of their length to the subulate gynobase, the ventral 
groove open and abruptly dilated at the bifurcate base. On dry hillsides, 
eastern Washington to California and Arizona. 
§ § Fruiting calyx persistent, open and discharging the fruit : nut- 
lets ail 4 or all but 1 scarious-winged at the margins, attached by the 
- whole length of the ventral groove. . 
C. pterocarya Greene l. c 120. K. pierocarya Gray. Papillose-hir- 
sute: stem slender, rather strictly branching, 6-12 inches high: leaves 
linear or the lowest spatulate, 6-12 lines long: spikes usually in pairs, 
bractless: sepals in fruit 2 lines long, ovate, rusty-hirsute and the midrib 
setose-hispid: nutlets oblong-ovate, rough or granulate-tuberculate on the 
rounded back, attached for nearly the whole length to the filiform-sub- 
ulate gynobase by a narrow groove which widens gradually to the base, 
one of them commonly wingless and rounded at the sides, the others 
with lateral angles extended into a broad radiately striate wing with 
crenulate or toothed or even pectinate margins. Dry sandy plains, eastern 
Washington to California, New Mexico and Arizona. | 
18 AMSINCKIA Lehm. Del. Sem. Hamb. 1831: 7. 
Coarse hispid annuals with alternate cblong-ovate to linear 
leaves and small yellow flowers in at length loose spikes-or ra- 
cemes without bracts except sometimes to the lowest. Calyx 
5-parted, persistent. Corolla salverform or at the throat some- 
what funnelform, more or less plaited in bud at the sinuses, with 
tube exceeding the calyx and rounded lobes, the throat naked, or 
with minute hairy tufts opposite the lobes. Filaments short. 
Style filiform; with capitate 2-lobed stigma. Nutlets ovate-tri- 
angular or triquetrous, coriaceous or crustaceous, attached above 
the middle to an oblong-pyramidal gynobase, the scar ovate or 
oblong. Cotyledons each 2-parted thus apparently four. 
A. intermedia F. & M. Ind Sem. Petrop. 26. Rough-hispid through - Pore 
ont: stem erect, usually 1-2 feet high and sparingly branched above;. the 
bristles even of the calyx white or merely yellowish: leaves linear or the 
lower ones lanceolate, 1-4 inches long: spikes solitary or in pairs: sepalS' 
narrowly lanceolate, obtuse, at length 44 inch long: corolla bright yellow, - 
_ 3-5 lines long, its tube equalling the calyx, the limb with very short, 
rounded lobes and no appendages in the throat: nutlets not half as long 
as the sepals, trigonous, carinate onthe back and strongly muriculate, 
attached near the base to the short conical gynobase. Dry plains, Brit. 
Columbia to California. 
A. lycopsoides Lehm. Del. Sem. Hamb. 1831, 7. Rather, sparingly 
setose-hispid with pungent bristles: stem rather weak, 1-4 feet. high with 
numerous loose straggling branches: leaves lanceolate to ovate-lanceolate, 1-4 
nches long, acute at the apex, hispid-ciliate: spikes usually in pairs, at length 
ong and sparsely-flowered: sepals linear-lanceolate, at length spreading and 
3 or 4 times longer than the nutlets, papillost-hispid: corolla almost 2 lines 
in diameter, somewhat funnelform, the tube but little longer than the calyx: 
nutlets oblong-ovate, about a line long, very rough muricate. In rich alluvial 
ground, western Oregon and Washington to California.
