This species at first suggests the common Isocarpha oppositifolia R. Br. 

 from which it is readily distinguished by the alternate upper leaves and 

 by the thin one-nerved blunt and strongly ciliated pales of the receptacle.

This species was originally characterized as a variety of G. patens 

 Gray with the following brief description, "With copious spreading 

 pubescence on the stem: pedicels 1-2.5 cm - long: pappus none." 

 Several specimens have since been examined and all possess the copious 

 spreading pubescence on stem, leaves, and in the inflorescence, thus 

 rendering it easily separated from G. microcephala Less, with which 

 it has been associated as a variety. Hereto are referred the following,
