Abstract

The new rank and combination Berberis extensiflora (Ahrendt) Bh.Adhikari & Harber is proposed based on morphological and molecular studies of the Himalayan species of Berberis (Berberidaceae). Morphologically, Berberis extensiflora differs from B. concinna Hook.f. by its much longer (3–4 cm) inflorescence with 2 or 3 flowers in umbels (vs < 2 cm long solitary flowers) and 10- to 13-seeded berries (vs 5- to 9-seeded berries). A detailed taxonomic description, notes on habitat and ecology, and colour photographs are provided.
