Celtis
''Celtis'' is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, widespread in warm temperate regions of the Northern Hemisphere. The genus is part of the extended hemp family (Cannabaceae).
Description
''Celtis'' species are generally medium-sized trees, reaching tall, rarely up to tall. The leaves are alternate, simple, long, ovate-acuminate, and evenly serrated margins. Diagnostically, ''Celtis'' can be very similar to trees in the Rosaceae and other rose motif families.
Small flowers of this monoecious plant appear in early spring while the leaves are still developing. Male flowers are longer and fuzzy. Female flowers are greenish and more rounded.
The fruit is a small drupe in diameter, edible in many species, with a dryish but sweet, sugary consistency, reminiscent of a date.
