var. assamica (Mast.) Kitamura. Leaves tapering to a long point larger than those of var. sinensis. The major source of commercial tea which is a stimulant containing caffeine, polyphenols and essential oils that give the beverage its flavour; also said to have medicinal properties. This variety is the source of Indian tea and the variety that is grown in tea plantations in Papua New Guinea and North Queensland (where the plantations at Innisfail were established by Dr Maruff in 1960. By 1970 they had trunks 10 cm thick).

var. sinensis is the tea plant of China and Japan; it differs from the above variety in not possessing long-tapered tips to the leaves. Dr Withers has stock of this variety imported by McArthur c. 1850.
