Asia
Location: map coordinates W-21 (near southwest corner of Warren-Franklin Hall), N 39°11'4'' W 75°32'37''
Planting history: presently unknown.
Description:
- medium-sized deciduous tree
- etymology: Quercus = the Latin name; acutissima = very sharply pointed (the leaf teeth)
- leaves with small, regular, teeth (hence common name “sawtooth”)
- monoecious (separate male and female flowers on same tree); flowers tiny; male flowers in drooping catkins, female flowers inconspicuous
- fruit is an acorn (develops from ovary of female flower); cup with distinctive soft bristles
- in the “red/black oak group”: leaf teeth with bristle-tips; acorn matures in 2 years, relatively bitter and inedible unless processed
- end buds clustered (typical of oaks)
- fast-growing
- wood prone to splitting/cracking; normally relegated to use for fencing
- in Delaware, cultivated and escaping to fields
