Cespitose perennial with a woody caudex, densely clothed with the old leaf-bases, stems few 

 to many, 15-25 cm. high, rather slender, sparsely setose. Leaves clustered on the crown of the 

 caudex branches, spatulate, obtuse, 4-8 cm. long, finely strigose and appressed-setulose and on 

 the upper side with pustulate bristles, the lower side densely and finely strigose with a few inter- 

 mingling pustulate hairs; petioles ciliate near the base with long white hairs; inflorescence 

 rather narrow, little or not at all interrupted, extending to the middle of the stem or a little 

 below, densely but weakly setose and hirsute ; sepals in fruit 8-10 mm. long ; corolla white, the 

 tube 3-5 mm. long, about equaled by the lobes ; nutlets lanceolate, 3-4 mm. long, acute on the 

 margins, dull, dorsal side densely rugulose with somewhat minute narrow ridges, conspicuously 

 muricate near the margins; scar narrow, slightly open, extending nearly to the apex, not 

 elevated on the margins.

Perennial with stout root; stems usually several from a branched root crown, stout, 15-25 

 cm. high, simple, or with 1 or more slender ascending branches from near the base, hirsute- 

 hispid with spreading setae and with a fine somewhat tomentose pubescence of reflexed hairs, 

 densely leafy at base. Leaves, especially the lower, spatulate, 2-3 cm. long, 5-7 mm. broad near 

 the rounded apex, canescent with a more or less appressed pubescence, the upper surface and 

 margins also with scattered ascending slender setae with pustulate bases; upper stem-leaves 

 gradually reduced, oblanceolate to narrowly linear-oblanceolate ; cymules several-flowered, in 

 fruit 1-2 cm. long, crowded into a rather dense terminal spike-like inflorescence, 6-10 cm. long, 

 or on some of the slender basal branches sometimes smaller; fruiting calyx-lobes 5-10 mm. 

 long, narrowly linear-lanceolate, bristly with spreading setae ; corolla white, 5-6 mm. long, limb 

 5 mm. broad ; nutlets ovate-lanceolate, subacute at apex, 3 mm. long, the margin sharply acute, 

 dorsal side brownish, somewhat glossy, tuberculate, some of the tubercles connected by slender 

 ridges to form a few rather inconspicuous rugae.
