Varieties: none
Description
Q. margarettae is a perennial shrub/tree of the Fagaceae family native to North America. [2]
Distribution
Q. margarettae is found in the southeastern corner of the United States from Texas to Virginia. [2]
Ecology
Habitat
Q. margarettae proliferates in sandhills, typically in slightly loamy or clayey soils, not usual in the deepest and most xeric sands. [1] Specimens have been collected from mixed woodland, longleaf pine-scrub oak, sandpine flatwoods with sandy soil, hardwood hammock, planted slash pine on sand ridge, longleaf pine wiregrass scrub oak ridge, hardwood stand, beach ridge, sand pine scrub, and loamy sand of xeric flatwoods.[3]
Q. maragarettae responds negatively to soil disturbance by agriculture in traditionally longleaf communities.[4] It also responds negatively to agricultural-based soil disturbance in South Carolina coastal plain communities. This marks it as a possible indicator species for remnant woodland.[5] Q. margarettae does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[6]
Phenology
Q. margarettae has been observed to flower March through June. [7]
Seed dispersal
This species is thought to be dispersed by gravity. [8]
