Cardamine libagouensis, a new species from Hubei, China

Cardamine libagouensis (Brassicaceae), a new species from Enshi City, Hubei, China, is described and illustrated. The new species is morphologically similar to C. engleriana , but differs by lacking stolons, basal leaves pinnate, sepals 1.0–1.5 mm long, silique 3–4 cm long, and seeds without wings. A preliminary molecular phylogenetic study based on ITS2 sequences suggests that C. libagouensis is closely related to C. engleriana and C. griffithii .
