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 % 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 all 4 or all but 1 scarious-winged at the margins, attached by the 

 whole length of the ventral groove. 



C. pterocarya Greene I. c 120. K. plerocarya 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 b£|,ck, attached for nearly the whole length to the filiform-sub-r 

 ulate gynobase by a narrow groove which widens gradually to the base, 

 one of them commonly wingless and roundei 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. 



13 AMSINCKIA Lehm. Del. Sem. Hamb. 1831: 7, 



Coarse hispid annuals with alternate oblong-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 fuhnelform, 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 - 

 bnt : 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 }4 ii^oh long: corolla bright yellow, 

 3-5 lines long, its tube equalling the calyx, tlie limb with very short 

 rounded lobes and no appendages in the throat : nutlets not half as long 

 as the sepals, trigonous, carinate on the 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, spailngly 

 setose-hispid with pungent bristles: stem rather weak, 1-4 feetrhigh with 

 numerous loose Btragu;ling branches: leaves lanceolate to ovate-lanceolate, 1-4 

 nohes long, acute at the apex, hispid-ciliate: spikes usually in pairs, at length 

 ong and sparsely-flowered: sepals lineai'-lanceolate, at length spreading and 

 3 or 4 times longer than the nutlets, papillose-hispid: corolla almost 2 lines 

 in diameter, somewhat funnelform, the tube but little longer than the calyx: 

 nutlets oblong-ovate, Hbout a line long, very rough muricate. In rich alluvial 

 ground, western Oregon and Washington to Ca,lifornia.
