 rounded or somewhat pointed lobes, occasional leaves having squarish lobes. 



Quercus stellata margaretta, forma stolonifera Sargent, a shrub, has smaller leaves and reproduces itself 

 in dense thickets by stoloniferous roots. According to C. S. Sargent (Bot. Gaz., LXV, 441, 1918), it occurs 

 in Alabama (vicinity of Selma, Dallas County) and is probably the one found on sandy hills west of 

 Oklahoma City, Okla.
