SAND POST OAK

Quercus margaretta  Ashe ex Small

(KWER-kus  mar-gar-ET-ta)

General:



This small, scrubby deciduous oak may grow up to 10 m. (30 ft.) tall with rounded lobed leaves.  It is an understory tree usually found in the company of Turkey Oaks, Q. laevis.  Note that it is a different species from Post Oak, Q. stellata.

The wood is useful as fence posts and firewood, but little else.  Acorns provide food for wildlife, but are of little value to humans because of the bitter taste.  It is a member of the red oak group, and is thought to hybridize with the Sand Live Oak.

Flowers / Fruit:

Flowers are inconspicuous; staminate flowers are arranged in catkins. 
The oblong acorns are about 1.5-2 cm. (3/8-5/8 in.) long with cups that enclose about 1/3 of the nut.  They take 2 years to mature.


Sand Post Oak  (Quercus margaretta)

Leaves / Stems:


Alternate, simple leaves have margins with 3 to 5 conspicuous lobes, usually rounded.  Leaves to 15 cm long and up to 12 cm wide.  It is distinguished from the Post Oak, Q. stellata, which has a larger leaf with more squared lobes and often is in the shape of a cross. 

The reddish brown to gray bark has ridges and fissures.

Distribution:
 
Found on deep sand ridges throughout the panhandle, east and south to the central peninsula.  It grows along the Coastal Plain from Florida to Alabama and Virginia.
