Sepals are lanceshaped, usually tinged with purple, almost black at the tip. Flowering stem is 4-8 cm tall, up to 18-28 cm in fruit, yellow powdery toward apex. Flowers are borne in a many flowered cluster, bracts linear-lanceolate, about 3-5 mm, base gibbous, apex acute. Flower-stalks are nearly absent or up to 1 mm. Black Sepal Primrose is found in the Himalayas, from Uttarakhand to SE Tibet, at altitudes of 3600-4900 m. Flowering: May-June.
