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 ovate-elliptic（ 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.
