What is the scientific name of the tea plant used to make black, green, white, and oolong tea?

Camellia sinensis is the scientific name of the tea plant used to make black, green, white, and oolong tea.

Camellia sinensis is an evergreen shrub or small tree native to East Asia and parts of the Indian subcontinent and Southeast Asia. The leaves and buds are harvested, then processed in different ways. Green tea is heated to limit oxidation, while black tea is allowed to oxidize much more extensively. Oolong tea occupies an intermediate processing range, and white tea generally uses young buds or leaves with minimal processing.

These beverages come from one species, not from separate plants. Herbal drinks such as chamomile or peppermint tea are infusions of other plants and are not true tea in the botanical sense. Two major cultivated varieties are commonly recognized: C. sinensis var. sinensis and C. sinensis var. assamica.
