G. heteroph^Ua, Nutt. Nearly smooth, a foot or two high, paniculately branched, or 

 the branches virgate : leaves rather erect, thickish or rigid ; the lowest 3-cleft or laciniate 

 (according to Nuttall] ; the others narrowly linear, mucronate-acute, scabrous on the mar- 

 gins ; those of the branchlets short and somewhat subulate : pedicels very short, alter- 

 nate: calyx-lol)es subulately attenuate from a broad base, very acute, in age spreading:
