Discussion | The name Gratiola flava has been widely used for G. torreyi. F. W. Pennell (1935) synonymized G. torreyi with G. neglecta, stating that the type of G. torreyi (Wright s.n., NY) has white corolla lobes and yellow corolla tubes instead of entirely golden yellow corollas as reported by Small in the protologue of G. torreyi. The statement by Pennell appears to be in error. M. H. MacRoberts et al. (2007) discussed historic and recent collections of Gratiola torreyi (as G. flava) from Louisiana. The provenance of collections attributed to Arkansas is equivocal (MacRoberts et al.). Gratiola pusilla Torrey ex Bentham 1846 (not Willdenow 1797) is an illegitimate name and pertains here.

Gratiola brevifolia is morphologically variable. In parts of its range, narrow-leaved plants approach G. ramosa and some broad-leaved plants approach G. viscidula. A population of G. brevifolia in Delaware is disjunct from the nearest conspecific population by more than 800 km (W. M. Knapp and D. Estes 2006).
