=9.= =Quercus imbricària= Michaux. Shingle Oak. Plate 48. Medium to large sized trees; leaves on petioles generally 0.5-1 cm. long, 7-16 cm. long, elliptic to oblong-lanceolate, narrowed or rounded at the base, apex generally sharp-pointed and ending with a bristle, sometimes very wide leaves are blunt at the apex, margins entire, when they first appear the upper surface is somewhat woolly and the under surface whitish with a dense tomentum, soon glabrous and a dark green above, remaining more or less densely woolly or pubescent beneath; acorns sessile or nearly so, solitary or in pairs; nuts ovoid, about 1 cm. long and enclosed for about 1/2 their length in the cup; cup rounded at the base; scales pubescent on the back and obtuse. =Distribution.=--Pennsylvania, Michigan to Nebraska, south to Georgia and west to Arkansas. Found throughout Indiana. It is essentially a tree of low ground, but it is sometimes found near the base of slopes, and in the knob area it is sometimes found on the crest of ridges. In all parts of Indiana except the southwestern part it is found only locally and then usually in colonies of a few trees. In Wells County, I know of only two trees located at the base of a slope bordering a pond in Jackson Township. In the southwestern part of the State it is frequent to a common tree in its peculiar habitat. It appears that when drainage basins decrease in size, and leave sandy river bottoms, and bordering low sand dunes, that the shingle oak is the first oak to occupy the area. On the sand ridges it is crowded out by the black, black jack and post oaks. In the bottoms it is succeeded by pin, Schneck's, Spanish, swamp white and post oaks. Special notes were made on its distribution on a trip through Gibson, Pike, Daviess, Greene and Sullivan Counties, going from Francisco northward through the Patoka bottoms where in many places it forms pure stands. Usually in situations a little higher than the pin oak zone. Thence eastward to Winslow and then north to Sandy Hook in Daviess County, thence north to Washington, Montgomery, Odon, Newberry, Lyons, Marco and Sullivan. In its habitat all along this route it was a frequent to a very common tree. A few miles northeast of Montgomery is a small area which a pioneer informed me was originally a prairie. Typical prairie plants are yet found along the roadside and fences in the area. I was informed that the shingle oak was the only species found on the area, and on the border of the area. It is believed the mass distribution of the species was in the area indicated by the preceding route. Both east and west of this area the species becomes less frequent. =Remarks.=--Wood similar to red oak, but much inferior. Evidently it is rather a slow growing tree, but it might find a use as a shade or ornamental tree in sandy habitats where the pin oak would not thrive. It is also called black oak, peach oak, jack oak and water oak. [Illustration: Plate 48.
