Pyrrocoma ckkpidinea. Many-Stemmed and low, 3 or 

 4 inches high, whitened w^ith a kind of soft silky wooHness :

stout, glabrous, the bark whitish, almost polished, racemose 

 from above the middle : basal leaves a foot long, including 

 the very broad and short scarcely petiolar base, narrow^ly 

 oblong-lanceolate, less than an inch wide, very coarsely and 

 evenly serrate-toothed, everyw^here glabrous except as to the 

 finely scabrous margin ; cauline leaves much reduced, vSessile, 

 more finely and more saliently serrate : heads small for the 

 plant, forming a vShort and rather strict raceme ; involucres

 sustaining 3 large and subcqual heads ; bark of stems reddened 

 and sparsely villous-tomentose ; herbage otherwise altogether 

 of a dull glaucescent green and rather firm ; basal leaves 

 elliptic-lanceolate, acute ; cauline spatulate-lanceolate to ovate-
