Navarretia subuligera Greene, Pittonia 1: 137. 1887. 



Erect, simple or branched, sometimes tufted annual, 3-15 cm. high, stems puberulent to 

 retrorse short-pilose. Leaves pinnatifid into filiform segments with 1-2 pairs of lobes, glabrous 

 to puberulent toward the base, upper leaves becoming rigidly spinose-pinnatifid ; inflorescence 

 capitate or a series of heads on short peduncles ; bracts broadly ovate with slender spiny lobes, 

 some proliferating, the rachis coriaceous, ovate and often keeled from the back, closely investing 

 a few flowers to form a sort of bur, glabrous except for the ciliate margin and for the inner face 

 at the top of the rachis ; calvx of 5 unequal lobes, 2 simple and acerose, the other 3 often reduced 

 to teeth, the lobes hairy within at the junction of the membrane; corolla white, very small, nar- 

 rowly funnelform, equaling or subequaling the longest calyx-lobe, throat 1.5 mm. long, lobes 

 1 mm. ; stamens inserted near the base of the throat and included, anthers minute, filaments equal 

 or unequal; style included, stigma 3-lobed; capsule membranous.

 the longer usually with a pair of acerose teeth near apex, puberulent, but with a few long coarse 

 hairs about midway, sinus-membrane forming a pseudotube 3^ mm. long; corolla funnelform, 

 4-lobed, yellow to cream-colored, 9-10.5 mm. long, tube 5-6 mm., throat 2-3 mm., lobes 1-1.5
