Chinkapin Castanea pumila (Linnaeus) Miller    Synonyms: Allegheny Chinkapin, Castanea ashei.
Kingdom Plantae   >   Division Tracheophyta   >   Class Magnoliopsida   >   Order Fagales   >   Family Fagaceae   >   Genus Castanea   

Status:

Chinkapin and American Chestnut are the only Maryland species in the genus Castanea. Chinkapin has been called the "mysterious sister" of American Chestnut because it is less well known. It is much smaller than American Chestnut was before the Chestnut blight nearly destroyed that species. Chinkapin is resistant to the blight.

Description:

Shrub or small tree, 2-10 m tall. Leaves oblong, whitish and hairy beneath. Bristly burs enclose usually a single seed, in contrast to American Chestnut's 1-4 seeds (Brown and Brown, 1972).

Where to find:

Most common in the eastern part of the state. On dry soils, in or along the borders of woodlands (Brown and Brown, 1972).

There are 142 records in the project database.
