• Species: ZipcodeZoo has pages for 395 species, subspecies, varieties, forms, and cultivars in the Tribe Juglandeae.

Genera

Austromyrtus

Austromyrtus is a genus of shrubs in the myrtle family Myrtaceae. The three species are found along the east coast of Australia, in Queensland and/or New South Wales. The fruits of A. dulcis have a hint of cinnamon flavouring. The species under this generic name in New Caledonia are being taxonomically revised and will be transferred to another genus. [more]

Cyclocarya

Cyclocarya is a genus of flowering plants in the family Juglandaceae, comprising a single species Cyclocarya paliurus (Wheel Wingnut), formerly treated in the genus Pterocarya as Pterocarya paliurus. It is native to eastern and central China. [more]

Juglans

Juglans is a plant genus of the family Juglandaceae, the seeds of which are known as walnuts. They are deciduous trees, 10?40 meters tall (about 30?130 ft), with pinnate leaves 200?900 millimetres long (7?35 in), with 5?25 leaflets; the shoots have chambered pith, a character shared with the wingnuts (Pterocarya), but not the hickories (Carya) in the same family. [more]

Persoonia

Persoonia is a genus of 98 species of shrubs and small trees in the tribe Persoonioideae in the large and diverse plant family Proteaceae. In the eastern states of Australia, they are commonly known as Geebungs, while in Western Australia and South Australia they go by the common name Snottygobbles. The generic name is in honour of Dutch mycologist and botanist Christiaan Hendrik Persoon. [more]

Pterocarya

The wingnuts are plants in the genus Pterocarya (from Ancient Greek pteron, "wing" + karyon, "nut") in the walnut family Juglandaceae, native to Asia. They are deciduous trees, 10-40m tall, with pinnate leaves 20-45cm long, with 11-25 leaflets; the shoots have chambered pith, a character shared with the walnuts (Juglans) but not the hickories (Carya) in the same family. [more]

At least 46 species and subspecies belong to the Genus Pterocarya.
