262 ASPERIFOLIiE. 



spicate or somewhat glomerate and leafy-bracted: calyx a line long, the 

 segments scarcely attenuate or prolonged above the nutlets; groove of 

 small ovate acute nutlet not forked at'base. — Sandy lands along the sea- 

 board. April — Aug. 



6. C. Torreyana (Gray), Greene. Erect, sparingly paniculate- 

 branched, 1 — 1% ft. high, hirsute-hispid, the calyx with rigid stinging 

 bristles, its sepals elongated and attenuate upward: nutlets ovate, acute, 

 the groove forked at base. — Very common among the hills and mountains, 

 in clayey soil. May — July. 



4-4— Nutlet solitary, three ovules being abortive. 



7. C. flaccida (Dougl.), Greene. Rigidly erect, slender, usually 

 simple up to the terminal set of rather strict spikes : minutely strigose- 

 hispid: fruiting calyx erect, appressed to the rachis, narrow and slender, 

 the filiform-linear sepals very hispid below with deflexed strong bristles: 

 nutlet subterete, ovate-lanceolate, rostellate-acuminate, shorter than the 

 sepals; groove enlarged below, but not furcate. — Very common on 

 stony hillsides almost everywhere. May, June. 



6. AMSINCKIA., Lehmann. Hispid annuals, with yellow flowers in 

 elongated spikes. Calyx herbaceous; sepals 5, or 4 by the union 

 of 2 into one broader one. Corolla salverform, the throat somewhat 

 funnelform, the aperture often angular by folds, the lobes rounded, rarely 

 somewhat unequal and the corolla therefore slightly bilabiate. Fila- 

 ments short; anthers oblong or oblong-linear. Style filiform; stigma 

 capitate, 2-lobed. Nutlets crustaceous, erect or incurved, smooth or 

 rugose, commonly more or less ovate-triquetrous. Cotyledons 2-parted. 



1. A. lycopsoides, Lehm. Herbage of a light yellowish-green, very 

 hispid, the bristles from a pustulate base: leaves in a rosulate tuft, 

 lanceolate, slenderly acuminate: stem at first erect, at length freely 

 branching und the branches trailing, 1 — 2^ ft. long: spikes more or less 

 leafy-bracted: sepals short: corolla pale yellow, very slender: nutlets % 

 line long, brown or blackish, rugulose and muriculate. — Sandy soils 

 along the seaboard. March — July. 



2. A. intermedia, Pisch. & Mey. Loosely branching above, 1 — 3 ft. 

 high, less hispid than the last, deep green: leaves linear, or the lowest 

 oblanceolate : sepals twice the length of the nutlets and half as long as 

 the deep yellow narrow corolla: anthers oblong: nutlets very much 

 incurved, carinate on the back, muricate-scabrous and obliquely rugose. 

 — Very common in the Bay region, in alluvial soils. April — June. 



3. A. spectabilis, Fisch. & Mey. Erect, slender, less hispid, 1—1 % 

 ft. high: leaves linear: sepals narrowly linear-lanceolate, elongated, 

 ferruginous-hispid: corolla orange-yellow, % — % in. long; lobes slightly 

 unequal: nutlets granulate-rugose, carinate on the back. — Hills of the 

 Mt. Diablo Range. March— May.
