Gratiola brevifolia

Gratiola brevifolia is a rhizomatous perennial. Its leaves are linear-lanceolate with a few coarse teeth distally. Its flowers have white lobes and a yellow tube with brown lines. It blooms from April to September.[3]

Gratiola brevifolia is similar to Gratiola vicidula, which has a range centered farther to the east. G. brevifolia can be distinguished by its narrower leaves and sepals.[4] It is also similar to Gratiola ramosa, a species that it co-occurs with on the Southeastern Coastal Plain, from which G. brevifolia can be distinguished by the regular presence of 1-2 bracts subtending the sepals.[4]
