glabrous or obscurely ciliate on the scarious margins: rays none or 
only 1 or 2 in each head, the ligule oblong-linear and conspicuous;

heads mostly terminal on the branchlets of the inflorescence, rather 
large (1 cm. or more), the narrowly linear foliar bracts passing into 
those of the involucre: rays conspicuous, 2-5, the ligule about
