We present a new record of the dogwood tree (Cornus kousa F. Buerger ex Hance subsp. kousa) (Cornaceae) from the Eastern Himalayas in India. This record extends the known geographical distribution of C. kousa from China, Republic of South Korea and Japan to Eastern Himalayas of the Indian biome. With this report, the distribution of the subspecies kousa is also extended from Japan and Korea to India. The species was discovered from Khangchendzonga Biosphere Reserve (27°06'-28°05'N, 88°02'-88°47'E) in the state of Sikkim in the Eastern Himalayas. This discovery modified the current distribution of C. kousa in the world.
