 ascending, thinly retrorse-hirsutulose, 6 to 12 inches high, these and the basal 

 leaves tufted on a branched root-crown, the root-ero%vn branches densely sheathed 

 by old stem and leaf bases ; herbage bright green, the leaves microscopically strigu- 

 lose, the hairs with black dots at base ; leaf-blades elliptic or elliptic-ovate, 1 to 2% 

 inches long, rather abruptly petioled, the petioles 1 to 2i/4 inches long; cauline 

 leaves reduced upwards, the upper ones sessile or subsessile, rounded or subcordate

 feet: Sierra Nevada, east side or high easterly plateaus in the Mount Whitney 

 region, Tulare and Inyo Cos. Aug. 



Endemism note. — Lappula sharsmithii, localized in the region of Mount Whitney at high alti- 

 tudes, has a longitudinal range of about 8 miles. Both in leafage and inflorescence it is a remark- 

 able species. First collected on Mt. Whitney in 1895 by C. A. Purpus, hia material (no. 1620), 

 scanty and depauperate, reveals only obscurely the true character of the species. It vras only 

 through ample recent collections that the peculiar validity of this high-montane endemic became 

 obviously apparent. The knowTi stations, all by the same collector, are as follows: Mirror Lake, 

 Lone Pine Canon; Consultation Lake, Sharsmith 3280; Mt. Muir (e. of), Sharsmith 3336; 

 Siberian Outpost (plateau sw.), Tulare Co., Sharsmith 3415.

9. L. californica Piper. Stems erect, V/o to 3 feet high ; herbage appressed- 

 pubescent or the hairs partially spreading on the stems and petioles ; leaf -blades 

 oblong (or some upper ones lanceolate), 2'/^ to 5^2 inches long, sessile, the lower 

 cauline and basal tapering to a petiole % to as long; panicles usually large and 

 widely branched ; calyx-lobes ovate, about equaling the corolla-tube ; corolla white
