Quercus prinoides is a shrubby tree to 3 m tall, colonial from stolons, white oak group (subgenus Lepidobalanus).
Leaves alternate, widest above middle, to 10 cm long, lobed like those of Q. prinus with 5-8 low, usually rounded teeth per side, base wedge-shaped, bright green above, white-hairy below, leaf stalk to 1 cm.
Flowers: male flowers elongate clusters of catkins, female flowers solitary or few, very small.
Fruit: mature acorns to almost 2 cm long, base rounded, cup covering about half of nut, scales fine. Seeds dispersed by squirrels, probably by blue jays (Johnson and Adkisson 1985), and other animals that bury acorns.
Wetland status: NL.
Frequency in NYC: Very infrequent.
Habitat: Dry, rocky or sandy, often on rich calcareous, soil pH 5-8.5. Oak barrens and scrub. Tolerant of drought. Intolerant of shade, flooding, soil compaction (Hightshoe 1988).
Notes: Acorns eaten by many birds and mammals that do not bury nuts (raccoon, foxes, deer, voles) white-tailed deer, squirrels and white-footed mice are major predators of acorns (Martin et al. 1951).
