Camellia sinensis var. taliensis
Camellia sinensis var. thaliensis (大理茶) is an endemic sub species of Camellia sinensis distributed in the Yunnan province of China and adjacent areas of Myanmar, Laos and Thailand. This variety is often encountered growing in a semi-wild or wild state and is traditionally used for producing Pu-erh tea by the local people of its growing area. It has also been of interest to researchers and tea breeders due to its genetic diversity and distinctive morphological traits compared to other tea varieties.
Taxonomy and Nomenclature
Camellia sinensis var. taliensis is sometimes treated as a distinct species, Camellia taliensis, due to notable morphological differences from the more widely cultivated varieties, such as Camellia sinensis var. sinensis (the Chinese-type tea) and Camellia sinensis var. assamica (the Assam-type tea). While taxonomic debates persist, most authorities recognize it as a botanical variety within the C. sinensis species complex. The name “taliensis” derives from its association with the region historically known as Tali (Dali) in Yunnan.
Description
Camellia sinensis var. taliensis generally exhibits larger leaves than the Chinese-type tea bush (C. s. var. sinensis) and often possesses a downy, hairy underside. The leaves are elliptical to oblong, with a leathery texture and a slightly serrated margin. Young shoots may also appear more prominently hairy. The plant typically grows at higher elevations, ranging from about 1,500 to 2,500 meters, in moist, forested environments.
Distribution and Habitat
This variety is native to the southwestern region of Yunnan, where climatic conditions—mild temperatures, sufficient rainfall, and rich biodiversity—support its growth. Small populations have also been identified in parts of Myanmar. Unlike widely cultivated tea plantations, C. s. var. taliensis often thrives in semi-wild habitats, including understories of evergreen broad-leaved forests. These environments contribute to the plant’s genetic variability and resilience to certain pests and diseases.
Cultivation and Use
Though less commonly cultivated than the major commercial tea varieties, Camellia sinensis var. taliensis has a long history of use by local ethnic groups. Its leaves are harvested to produce teas that can be consumed fresh or processed into traditional styles somewhat similar to pu’er or other fermented teas of Yunnan. These teas are valued for their distinct flavor profiles, often described as fragrant, mellow, and complex, and for their cultural significance within local communities.
Genetic Importance and Conservation
As a relatively undomesticated tea variety, C. s. var. taliensis holds substantial genetic importance. Its wild or semi-wild populations serve as reservoirs of genetic traits that may be beneficial for tea breeding programs. These traits include potential disease resistance, adaptability to particular climates, and unique flavor compounds. Conservation efforts focus on protecting the natural habitats where this variety grows to maintain genetic diversity, support sustainable harvesting practices, and ensure that future generations can continue to enjoy and study this valuable tea lineage.
Research and Studies
Ongoing scientific research involves examining the genetic relationships between C. s. var. taliensis and other tea varieties, identifying distinct phytochemical compounds, and evaluating its potential for use in developing new tea cultivars. Studies have also explored the cultural and ethnobotanical aspects of its use, shedding light on the plant’s role in the traditions, economies, and gastronomy of the region’s indigenous communities.
