 scarcely scabrid ; leaves opposite, spreading, lance-shaj)ed, rather 

 obtuse and minutely mucionate at the apex, broadly cordate or 

 subreniform at the l)ase, membranous but rather ligid, rather 

 distantly crenulate-denticulate, scabrid scattered with short

 and acuminate, ciliate, fiat, the outermost ones rather the 

 shortest ; flowers wholly golden-yellow ; ray-florets about |- in. 

 long, uniseriate, female, fertile, subtended by the innermost 

 scales of the involucre, ligulate ; the ligule oblong, j} in. long, 

 marked Avith several parallel longitudinal nei'ves, biiid at the 

 apex, glabrous above, pilose along the nei-ves beneath ; stjde bifid; 

 the ovary compressed-subquadrangular, puberulous along the 

 lateral edges, otherwise glabrous or minutely puberulous obovate, 

 y\- in. long, subtruncate at the apex, tipped with about ten

 slightly compressed, angular, glabrate except the somewhat 

 rounded or subtruncate apex, yV in. long; pappus consisting 

 of several erect pallid scabrid more or less deciduous aristaj 

 which equal or exceed the achene in length and arise about a 

 thickened ring narrower than the whole achene; receptacle
