The Bur Oak ranges from jNIanitoba to Texas and from the foot-hills of tlie Rocky Mountains to the Atlantic coast. It goes farthei' to the northwest than any other of our eastern oaks, it varies in size from a shrub in Manitoba, to a magnifi- cent tree one iiundred and sixt\' feet high m southern Illinois. It is the most abundant oak of Kansas and of Nebraska, it forms the scattered forests known as " The Oak Openings " of jNIinnesota. Three inarked characters distinguish the Bur Oak. Its leaves have a pectiliar though variable outline which is un- mistakable, rarelv if ever are tv.'o alike, yet all bear so marked a resemblance that there is no difficulty in distinguishing them. Every Bur Oak leaf is somewhere, usually about the middle, cut by two opposite sinuses nearly to the midrib. Tlie terminal lobe so formed may itself be lobed or toothed or re- pand, the lower division may be lobed cir entire, but with all these variations the leaves retain a general siniilaritv. In the spring they are yellow green as they burst from the bud and do not like so many others take on a stain of red. At first they are downy and woolly but soon become smooth and shining. The leaves spread out horizontally from the new shoots and the aments hang down in thick clusters. Their autumn col- 336.
