PARONYCHIEiE. 



Paeonychu pulvinata. Gray. Proc. Acad. Phil, Mar. 1863, p. 58. 

 Matted-csespitose from a woody root, nearly glabrous; stipules silvery, 

 broadly ovate, entire, pointless ; leaves thick, oblong, obtuse, ciliolate-scab- 

 rous upon the margin and somewhat minutely glandular-pubescent, equaling 

 the stipules and with them densely covering the short stems ; flower solitary, 

 terminal, sessile; sepals oval, broadly scarious, awned a little below the 

 somewhat arched apex. — Alpine, forming dense cushion-like tufts, occasion- 

 ally sending out short nearly naked pubescent stems ; stipules 2" long, the 

 uppermost somewhat acute but blunt; leaves 2J-3" long and 1" wide, 

 bright-green and nerveless ; flowers immersed among the leaves ; stamino- 

 dia 5, similar to the fertile filaments ; ovary glabrous, tapering into the rather 

 short style. Rocky Mountains of Colorado. Uinta Mountains, Utah, above

 See Appendix, under Eriogoneee.) Matted-csespitose ; leaves 3-6" long, 

 mostly rosulate on the prostrate branches of the caudex, spatulate, hoary- 

 tomentose on both sides, the margins more or less revolute ; scape leafless, 

 1-3' high ; involucre solitary, naked, deeply 6-8-cleft, the lobes narrow,

 panulate, top-shaped, or cylindric, usually 5-8-toothed or lobed, pointless. Flowers jointed upon their 

 pedicels, which are more or less exserted from the involucre in flower ; bractlets usually very delicate or 

 very narrow. Calyx 6-parted or deeply 6-cleft. Stamens 9. Achenium triangular, or in a few species 

 3- winged,— North American herbs or undershrubs, mostly west of the Mississippi. T. & G., I. o.
