'''''Trochodendron''''' is a genus of [[flowering plant]]s with one living species ''[[Trochodendron aralioides]]'' and five extinct species known from the fossil record. It was often considered the sole genus in the family [[Trochodendraceae]], though botanists now include the distinct genus ''[[Tetracentron]]'' in the family [[Trochodendraceae]] also. ''Trochodendron'' is native to [[Japan]], southern [[Korea]], [[Taiwan]] and the [[Ryukyu Islands]] with fossils know from [[North America]] and [[Europe]].<ref name="Pigg2001">{{cite journal |last1=Pigg |first1=K.B. |coauthor1=Wehr, W.C. |coauthor2=Ickert-Bond, S.M. |year=2001 |title=''Trochodendron'' and ''Nordenskioldia'' (Trochodendraceae) from the Middle Eocene of Washington State, U.S.A. |journal= International Journal of Plant Sciences |volume=162 |issue= 5 |pages=1187-1198 |doi= 10.1086/321927}}</ref> ''Trochodendron aralioides'' is an [[evergreen]] [[tree]] or large [[shrub]] growing to 20 m tall. ''Trochodendron'' shares with ''Tetracentron'' the very unusual feature in [[flowering plant|angiosperms]], of lacking [[vessel element]]s in its [[wood]]. This has long been considered a very primitive character, resulting in the classification of these two genera in a basal position in the angiosperms; however, genetic research by the [[Angiosperm Phylogeny Group]] has shown it to be in a less basal position (early in the [[eudicot]]s), suggesting the absence of vessel elements is a secondarily evolved character, not a primitive one. {{Inc| Trochodendron (Greek, wheel and tree, alluding to the appearance of the fls., the anthers of the numerous spreading stamens forming a ring.). Trochodendraceae. Evergreen tree with aromatic bark and foliage, with alternate or whorled long-petioled lvs. and small fls. in terminal upright racemes: fls. long-pedicelled, perfect, without perianth; stamens numerous, filaments slender: carpels 6-10 in one whorl, connate below, with short linear spreading styles: fr. consisting of 6-10 follicles inserted below in the fleshy receptacle, dehiscent at the apex, with several linear seeds in each carpel. The tree is probably not in cult. in this country, but may be recommended for its handsome evergreen foliage for the middle and southern Atlantic states and for Calif. T. aralioides, Sieb. & Zucc. Tree, to 50 ft., or in cult. spreading shrub, glabrous: lvs. rhombic-obovate to elliptic-lanceolate, obtusely acuminate, crenate-serrate, lustrous and dark green above, lighter green beneath, 2-5 in. long; petioles 1-3 in. long: fls. green, 3/4 in. broad across the stamens; anthers yellow: fr. brown, 1/2 – 3/4 in. across.
