folds) ; annuals; widespread 10. Amsinckia. 



Corolla white or cream-color or pale yellow, the throat with more or less prominent bulbous 

 swellings or crests. 

 Perennials, mostly caespitose; calyx persistent; nutlets not carinate or only medianly 



lineate; mostly high montane 11. Oreocaeta. 



Annuals (except 1 or 2 perennial species in Cryptantha and Allocarya) ; mostly low 

 altitudes. 

 Calyx cucumscissUe (cf. also 2 species of Plagiobothrys, no. 17) ; transmontane 



deserts and intramontane meadows or slopes _ 12. Geeeneochakis. 



Calyx not circumseissile. 



Nutlets not keeled ventrally (nor dorsally or only obscurely or partially at 



apex), grooved ventrally above the basal scar, usually erect, attached 



from the basal scar to the middle or to the apex along the ventral 



groove; calyx (and pedicels) usually falling away with the fruit; 



corolla-throat with crests; leaves commonly alternate. 



Stems irregularly branched ; spikes bractless or irregularly f ew-bracteate 



(especially toward base), rarely bracteate throughout and then 



the bracts unequal; gynobase subulate; style not dilated in fruit; 



widespread 13. Cryptantha, 



Stems dichotomously branched; racemes spike-like, regularly and equally 

 bracteate (each flower subtended by a bract) ; gynobase colum- 

 nar; style dilated in fruit; mostly deserts and intramontane 



slopes 14. Eremocakya. 



Nutlets keeled ventrally and often also dorsally; ventral groove none or rarely 



present and then enclosing the keel; calyx and pedicels persistent; 



corolla-throat with only obscure crests. 



Nutlets mostly erect, attached by a scar or groove but not caruncular; 



corolla white with yellow throat (often fading) ; lower leaves 



opposite, not in a basal rosette; widespread 15. Allocakya. 



Nutlets oblique or incurved so that the apices are approximate in center, 

 attached above the base to a thickened scar or caruncle; corolla 

 entirely white. 

 Caruncle borne on a stipe-like base ; leaves alternate, the lowest not in 



a rosette; South Coast Ranges and coastal S. Cal 



16. Echidiocaeya. 



Caruncle commonly borne in a hollow or transverse groove; leaves 



mostly in a basal rosette, the cauline alternate ; widespread.... 



17. Plagiobothrys. 



2. Calyx-lohes armed with iaried pricMes, the calyx in fruit modified to form a bur-like envelope 



for the nutlets; annual; S. Cal 18. Harpagonella. 



1. EUPLOCANutt. 



Small annuals. Flowers solitary. Corolla white, the upper part of the tube en- 

 larged and the orifice narrowed, the limb scarcely lobed. Anthers ovate-lanceolate, 

 inserted midway of the coroUa-tube. Style elongated, its stigma annular or 2-lobed, 

 surmounted by a conspicuous tuft of bristles. Fruit didymous, each globose half 

 splitting into 2 hemispherical oue-seeded nutlets. — Species 1. (Greek eu, well, 

 and ploke, a woven thing. ) 



1. E. albiflora Jtn. var. californica ( Greene) Jepson & Hoover comb. n. Stem 

 branched, 1 to 3 inches high; leaf -blades, calyx, corolla-tube and midnerve of limb 

 strigose-hispid, the stems and petioles mostly spreading-hispid, all the hairs pustu- 

 late at base ; leaf -blades ovate to oblong-lanceolate, 5 to 15 lines long, petioled ; 

 flowers "sweet-scented," borne on short (V2 line) pedicels; corolla 5 lines broad; 

 fruit hairy. 



Desert sandhills, flats and playas, 200 to 1800 feet : eastern Mohave Desert ; 

 northeastern Colorado Desert. East to Arizona. Apr.-May. 



Locs. — E. Mohave Desert: Calico Mine (near), K. Brandegee; Ludlow, Jepson 5497; Soda 

 Lake, near Baker, Parish 9875 ; Kelso Sand Dunes, ace. Mary Beal. Ne. Colorado Desert : Marie 

 Mts., Schellenger. These California collections, as representing the variety, differ from the spe- 

 cies eastward only in the spreading hairs of stems and petioles.
