you could distinguish oaks from other trees by the folio buds that form in clusters at the end of twigs and their acorn . In the late spring , oak treesproduce long strings of manly blossom called catkins . Shortly thereafter , acorn begin get . Although many people associate oak tree tree with their iconic lobate leaves , some of the oak in North Carolina develop oblong leaf shapes without lobe . Duke University ’s web site key 29 dissimilar oak tree specie in North Carolina , 28 of which are natives . Distinguishing between the most rough-cut variety need mainly observing trait of the leaves , acorn and the tree ’s habitat .

Step 1

draw the shape of the leaves . minute , tapering leaves without lobe go to the willow tree oak ( Quercus phellos ) . Leaves that start narrow and widen to a broad , orotund tip , also lack lobe , belong to the laurel oak ( Q. hemisphaerica ) . leave with three sharp points at right angles from each other go to the dud oak ( Q. laevis ) , key out for the leaf ’s resemblance to a turkey animal foot .

Step 2

Note whether leaf lobe are attack or point . Rounded lobe indicate that the tree belongs to the white oak group , while pointed lobe belong to the red oak group .

Step 3

Count the number of lobes on a leaf with rounded lobes and observe whether they are shallow or deep . Seven or more deep lobe indicate an eastern white oak ( Q. alba ) , while fewer than seven indicate a military post oak ( Q. stellata ) or overcup oak tree ( Q. lyrata ) . To distinguish between the latter , get hold an acorn from the tree diagram . The pileus on overcup oak acorns almost totally covers the nut .

Step 4

note the tree diagram ’s use , if the leafage has round , shallow lobe . The swamp chestnut tree oak ( Q. michauxii ) inhabits wetlands , while you ’ll find the chestnut tree oak ( Q. montana ) on dry higher ground .

Step 5

experience the underside of leaves with three pointy , shallow lobes . The body of water oak ( Q. nigra ) feels fluent on the undersides of the leaves , while the blackjack oak ( Q. marilandica ) and the southerly red oak ( Q. falcata ) have bleary undersurface . Leaf staunch on the blackjack oak measure less than an in in length , while stems on the southern red oak grow 1 to 2 in .

Step 6

scratch the undersides of a leaf with five to 12 pointy lobes . Lobes may be deep or shallow . Eastern black oaks ( Q. velutina ) finger rough and blurry underneath , and the bull chafe off . The cherrybark ( Q. pagoda ) and southern red oak ( Q. falcata ) have fuzzy undersurface , but the whisker do not come off . The northern crimson oak ( Quercus rubra ) feels placid beneath , and lobes extend less than 2/3 to the midrib . Deeply lobed leaves with smooth bottom belong to the vermilion oak ( Q. coccinea ) and Shumard oak ( Q. shumardii ) , with the former occupying dry upland forests and the latter find oneself in moist lowland forests .
