Discussion

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).
