Key to the species of Castanea

The key below should be used with caution; breeding programs have produced hybrids of C. dentata with various combinations of non-native chestnut species, identifying these hybrids are problematic at best.

1. Leaves nearly glabrous beneath (mature lvs. of C. sativa may be nearly glabrous)...Castanea dentata

1. Leaves markedly pubescent beneath...2

 

2. Shrub to small tree, less than 10 m tall…3

2. Large trees, 20-30 m tall…4

 

3. Leaves without lepidote glands beneath; solitary nut…Castanea pumila

3. Leaves with lepidote glands beneath; 2-3 nuts…Castanea crenata

 

4. Leaves without lepidote glands beneath…Castanea mollissima

4. Leaves with lepidote glands beneath…Castanea sativa
