Bergenia purpurascens (Hook.f. & Thomson) Engl.
An excellent species found in open and semi-shaded habitats, such as forests, scrub, alpine meadows and alpine rock crevices, often in rocky and wet areas, at 1800-5100m across India (Sikkim, N. Assam), E. Nepal, N. Bhutan, S.E. Tibet and China (S.W. Sichuan, E. and S. Xizang, and N. Yunnan).
The leaves are generally elliptic to ovate-elliptic and rounded at both the apex and base with a smooth, entire margin that can be sinuous or denticulate. Hair-like teeth occasionally appear at the base. Deep purple-red or bright pink flowers, often becoming red with age, open from dark red calyces atop a branching red stem in spring.
The species is used medicinally and is a source of bergenin.
