[ 3 ] It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas , inland as far as ...
Quercus myrsinifolia is an evergreen oak tree that grows up to 20 metres (66 ft) tall. Leaves are 60–110 × 18–40 mm with serrulate margins; the petiole is 10–25 mm long. The acorns are ovoid to ellipsoid, 14–25 × 10–15 mm, and glabrous with a rounded apex; the flat scar is approx. 6 mm in diameter. Cupules are 5–8 × 10–18 mm ...
Together with larva of the filbertworm moth (Cydia latiferreana), the filbert weevil feeds on the acorns of several species of oak tree. In British Columbia, up to 66% of acorns from garry oak (Quercus garryana) were infected with these larvae. These acorns are still able to germinate, but the germination rate is lower than for uninfected nuts. [2]
Acorns per pound range from 200 to 750. Acorns mature from August to November of the second year. Trees begin bearing acorns when they are about 25 years old, and optimum production is reached when they are between 50 and 75 years of age. Good acorn crops are frequent, occurring at 1- or 2-year intervals, with light crops in intervening years.
It is in the white oak section, Quercus sect. Quercus, and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak (thus the species name macrocarpa , from Ancient Greek μακρός makrós "large" and καρπός karpós "fruit"), and are important food for wildlife.
Many animals eat unripe acorns on the tree or ripe acorns from the ground, with no reproductive benefit to the oak, but some animals, such as squirrels and jays serve as seed dispersal agents. Jays and squirrels that scatter-hoard acorns in caches for future use effectively plant acorns in a variety of locations in which it is possible for them ...

It is a large shrub or tree [5] growing to 22 metres (72 feet) tall, although where it is common in the low-elevation Sierra Nevada foothills it seldom exceeds 10 m (33 ft). The dark-green leaves —appearing grayish from a distance—are usually small, 2–7 centimetres (1–3 inches) long, [ 6 ] thick, and often spiny-toothed at higher ...
