Originally described in the genus
Flacourtia (
F. turbinata) based on limited material (no male individuals), this unusual species is now recognized as the sole member of the genus
Dianyuea, and is the only other member of subfamily
Scyphostegioideae of
Salicaceae. In addition to
phylogenetic analyses of DNA data, the species's
basal placentation,
connate stamen filaments, and seeds with
arilloid appendages indicate that this species is related to
Scyphostegia, a
monotypic genus which is now placed in a broadly circumscribed
Salicaceae. The genus is named after Dian-Yue (Chinese: 滇越), an ancient kingdom on the
Southern Silk Road, where the species is found. ==References==
