アッサム
The introduction of the Assam tea bush to Europe is related to Robert Bruce, a Scottish adventurer, who apparently encountered it in the year 1823. Bruce reportedly found the plant growing "wild" in Assam while trading in the region. Maniram Dewan directed him to the local Singpho chief Bessa Gam. Bruce noticed local people (the Singhpos) brewing tea from the leaves of the bush and arranged with the local chiefs to provide him with samples of the leaves and seeds, which he planned to have scientifically examined. Robert Bruce died shortly thereafter, without having seen the plant properly classified. It was not until the early 1830s that Robert’s brother, Charles, arranged for a few leaves from the Assam tea bush to be sent to the botanical gardens in Calcutta for proper examination. There, the plant was finally identified as a variety of tea, or "Camellia sinensis" var "assamica", but different from the Chinese version ("Camellia sinensis" var. "sinensis").
