Vitis heyneana is a species of climbing vine in the grape familyendemic to Asia. It can be found in shrubby or forested areas, from almost sea-level, to 3200 meters above. It has globose berries (10–13 mm diam.) that are purple to almost black.
Vitis heyneana is known by its two subspecies: V. h. subsp. heyneana (autonym), and V. h. subsp. ficifolia. In Chinese, the former is called mao pu tao, meaning wool grape; it has leaves that range in shape from oval, ovate-oblong, to ovate-quinquangular. The latter subspecies is called sang ye pu tao, or mulberry-leaf grape, and its leaves are usually trilobate to cleft (a few leaves interspersed on a vine will be undivided).[1][2][3] However, V. h. subsp. ficifolia may be a homotypic synonym of Vitis ficifoliaBunge, as the same type was used for both.[4]
The success of V. h. subsp. heyneana in multiplying itself in so many places, in contrast to the relatively limited range V. h. subsp. ficifolia correlates similarly with how well it manages to survive at higher altitudes[2][3]
V. h. subsp. heyneana : 100–3200 meters above sea-level
V. h. subsp. ficifolia : 100–1300 meters above sea-level
