 alt., in crevices of s 



Stems and petioles filiform ; leaves all alternate, doubly 

 and coarsely dentate, thin; whole plant sparsely floccose- 

 villous, even to the head; otherwise much as the type. 

 This plant grows on rocks in delicate tufts, about 6' long, 

 the stems are weakly, and ascending or pendent. 



About 6' high, in dense tufts from woody base, stems 

 branched above and branches 2-3' long and crowned by 

 the solitary head whose proper peduncle is 1' or less long; 

 leaves all alternate, lanceolate to broadly ovate, all with a 

 cuneate base, petiole equaling or half shorter than blade, 

 2-6" long exclusive of the petiole, not veiny, entire or in 

 the forms with larger leaves coarsely few-dentate, acutish; 

 stems terete, slender; whole plant very rough-scabrous; 

 heads campanulate, about 3" high, 15-20 flowered, cream- 

 colored, rayless; scales narrowly oblong to nearly linear, 

 about 12, acute; akenes very scabrous throughout, with 

 one slender awn, nearly equaling the akene. Whether 

 this and L. tcncUa, which is also rayless, vary into Z. 

 Palmcri can only be conjectured. If the leaf characters 

 hold they are certainly good species.
