(Rubus ellipticus)
Rubus ellipticus, commonly known as ainselu, golden evergreen raspberry, golden Himalayan raspberry, or yellow Himalayan raspberry, is an Asian species of thorny fruiting shrub in the rose family. It is native to China, Nepal, the Indian subcontinent, Indochina, and the Philippines. The golden Himalayan raspberry is a large shrub with stout stems that can grow to up to 4.5 metres (15 ft) long. Its leaves are trifoliate, elliptic, or obovate and toothed with long bristles. Its leaves can grow to up to 5 to 10 cm (2 to 4 in) long. Its flowers are short, white, and have five petals and grow in clusters, and blooms in the Himalayas between the months of February and April. Its fruit are sweet, detachable, and highly sought after by birds and elephants. Rubus ellipticus is sweet to the taste, though it is not commonly harvested for domestic use. The fruit perishes quickly after plucking from the thorny bush. The bark from this plant is used for medical reasons in Tibetan villages, mainly as a renal tonic and an antidiuretic. Its juices can also be used to treat coughs, fevers, colic and sore throat. The plant can also be used to make a bluish-purple dye.
