Flowering branch ; A, Staminate flowers ; B, Pistillate flowers THE BLACK OAK (Quercus velutina) The opening leaves are crimson, with silvery velvet linings and long white hairs above. Half-grown acorns are seen below thefringe of staminate catkins. The pistillate flowers arc in the leaf angles The Oaks a large group which takes two years to ripen an acorn crop. As arule, these trees always show half-formed acorns on their terminaltwigs in winter. The white or annual-fruited oaks never carryany over; they ripen their fruits and cast them in the autumn.Black oaks have bristly pointed leaves; white oaks have onlycurved lines on their leaf margins. These facts are well worthremembering. Most people know an oak just by the looks of it. Askthem which oak it is, and they cant be sure. The bark of theblack oak, with its orange lining, is the key to its name. Thewoodsman knows that this oak leads the country as the sourceof tan bark. Only the chestnut oak comes near it in percentageof tannin.
