General Description
Spurred Gentian is a glabrous annual herb with erect, simple or branched stems that are 5-30 cm high. The opposite, lance-shaped leaves are 2-4 cm long and have entire margins. The basal leaves have short petioles, while the upper are sessile. Loose clusters of 2-9 yellowish to purplish green flowers arise from the stem tips and from the axils of the upper leaves. Each flower has 4 narrow sepals that are ca. 5 mm long and a broadly tubular, deeply 4-lobed corolla that is 6-12 mm long with a spur at the base of each lobe. The cone-shaped seed capsule protrudes beyond the corolla at maturity.

Flowering in July.
