Davidia involucrata

Davidia involucrata, the dove-tree,[1] handkerchief tree, pocket handkerchief tree, or ghost tree, is a medium-sized deciduous tree in the family Nyssaceae.[2] It was previously included with tupelos in the dogwood family, Cornaceae.[3] It is native to South Central and Southwest China from Hubei to southern Gansu, south to Guizhou, Sichuan and Yunnan, but is widely cultivated elsewhere.

Davidia involucrata is the only member of its genus, but there are two varieties differing slightly in their leaves, D. involucrata var. involucrata, which has the leaves thinly pubescent (short-haired) on the underside, and D. involucrata var. vilmoriniana, with glabrous (hairless) leaves.[4] Some botanists treat them as distinct species, with good reason, as the two taxa have differing chromosome numbers so are unable to produce fertile hybrid offspring.
