FIG. 299. ACORNS AND LEAVES OF PEDUNCULATE OAK (Quercus pedunculata). 



This form of the Common Oak (Querdis robur) is by some authors considered a distinct species. Its distinguishing characters 



are the leaves are nearly or quite without stalks, and the flowers and acorns are on long stalks. The Oak is native from 



the Atlas range and Syria in the south almost up to the Arctic circle.
