 lobed above the middle, about half grown when the flowers open early in June and then 

 covered above with short soft pale hairs and pale-tomentose below, and at maturity dark 

 dull green and smooth or scabrate above, pale-tomentulose below, especially on the slender

 rowly obconic, tomentose, the lobes acuminate, glandular-serrate, sparingly villose; stamens 

 10; anthers rose color; styles 2 or 3. Fruit ripening the middle of September, on elongated 

 slightly villose pedicels, in broad lax drooping many-fruited clusters, globose to subglobose,

A tree, sometimes 20 high, with a short trunk 6'-8' in diameter, covered with gray scaly
