Malus sikkimensis is a rare species of apple known by the common name Sikkim crabapple.
It bears white and pink flowers and dark red fruit.
[1] It is native to China, Nepal, Bhutan, Assam, Tibet and parts of India, where it is threatened due to loss of habitat.
[2] The edible fruits are a primary source (within India and the Himalayas) of dietary dihydrochalcones and flavonoids (both organic compounds).
