It is sometimesdifficult to distinguish this from the varietytinctoria of Quercus coccinea, unless the eyehas been trained to close obsei-vation of tlieircharacteristics. The leaves of Quercus rubraare usually larger, with about four lobes on eachside; the lobes are al-so more uniform, and pointforward more strongly toward the apex of theleaf. The acorns are mucli larger than in anyof the varieties of Quercus coccinea (seldom lessthan one inch long), and are (jnite constant insize and shape. The cup is always shallow, andabout as wide as the acorn is long. A variety,runcinata, found near St. Louis, has a narrowerleaf, with more numerous and shorter lobes. (FiK 22(! ). Spanish Oak (Quercus faleata, Miclix.) Tliis is a tree of large size, confined in its rangemostly to the Southern States, occurring, how-ever, in New Jersey, Pennsylvania, Kentucky,Southern Illinois, Missouri, and probably in allthe States South. The leaves are usually long-stalked, large, and of peculiar shape, being 376 THE AMERICAN rounded attlie base and sending ont on each sideone or two long, narrow and somewtat hooked,or sickle-shaped, lobes; the apex, or point, beiogalso sometimes much ]Drolonged, narrow, andsomewhat toothed; the under surface is coveredwith a rusty colored down. The acorn is small(rather less than half an inch), roundish, and ina shallow cup. The leaves of this species pre-sent considerable diversity of size and shape,probably in some cases as the result of hybridiza-tion. The bark is said to be excellent for tan-ning. A variety, triloba, found in New Jerseyand elsewhere, is probably a hybrid betweenthis species and Q
