variously disposed heads of white or flesh-colored flowers in late 
summer. Scales of the campanulate involucre imbricated lan- 
ceolate or linear, the exterior shorter, none herbaceous, Recep-

viscid-pubescent: stems slender, 10-16 inches high, numerous from a 
woody, perennial base, sparingly branched above or simple: leaves ovate,

forming accessary loose bracts to the involucre proper: heads terminal, 9 
lines high; involueral bracts lanceolate and linear, acuminate glabrous: 
achenes not glandular, glabrous or the upper part hirtellous with a few- 
scattered hairs.on the ribs: pappus bristles subplumous. In gravelly 
gulches and along streams, southern Oregon and northern California.
