Juglandoideae
Jugandoideae is a subfamily of the walnut family Juglandaceae. This clade was first described by Gen-ichi Koidzumi, Koidzumi in 1937 by the name "Drupoideae," based on the drupe-like fruits of ''Juglans'' and ''Carya''. This name was rejected because it was not based on the name of the type genus. Jean-François Leroy (botanist), Leroy (1955) and Hans Melchior, Melchior (1964) both published descriptions of the clade using the name "Jugandoideae," but both were deemed invalid due to technicalities. The first valid publication of the name was by Wayne Eyer Manning, Manning (1978). *Subfamily Juglandoideae Manning (1978) **Tribe Caryeae Koidz. (1937) ***''hickory, Carya'' Nutt. – hickory and pecan ***''Annamocarya'' A.Chev. ***''Platycarya'' Siebold & Zucc. **Tribe Juglandeae Nakai (1933) ***''Cyclocarya'' Iljinsk – wheel wingnut ***''Juglans'' L. – walnut ***''Pterocarya'' Kunth – wingnut Manos and Stone (2001) proposed the following reorganization to refl ...

Rhoiptelea
''Rhoiptelea'' is a monotypic genus of flowering plants in the family Juglandaceae. It contains a single species, ''Rhoiptelea chiliantha'', commonly known as the horsetail tree. This genus was previously recognized in its own family, Rhoipteleaceae, but the APG III system of 2009 placed it in the Juglandaceae family. ''Rhoiptelea chiliantha'' is native to southwest China and north Vietnam and lives at the elevation of 700-1600m in mountainous areas. The trees are wind-pollinated, the flowers arranged in large sagged panicles usually 32 cm long like horse tails, and the fruit is a small botanical nut (fruit), nut with rounded wings. The leaf, leaves are pinnately compound and papery. The trees are usually 17 m high and with 40 cm diameter. It is a protected species of China. References
