Abstract
Eurya makuanica Ye Chuangxing et Shi xianggang
a new species of Theaceae
from Yunnan
China
is described and illustrated. It is morphologically similar to E. wuliangshanensis Ming
but differs from the latter by the following characteristics: leaves thinly leathery to papery (vs leathery in E.wuliangshanensis)
leaves blade ovateelliptic (vs oblong)
apex caudate (vs acuminate)
secondary veins obviously impressed above (vs slightly raised); sepals and petals suborbicular (vs ovate). The new species is rare and currently only known in the mountain nearby kashang forest farms in Yunnan province.
