=Tsuga canadénsis= (Linnæus) Carrière. Hemlock. Plate 6. Tall trees, 3-7 dm. in diameter, with reddish-brown or grayish bark, deeply furrowed; shoots very slender and hairy, becoming smooth in a few years; leaves apparently 2-ranked, persisting for about three years, linear, short petioled, 6-13 mm. long, usually about 10 mm. long, usually flat, obtuse or notched at apex, bright green and shiny above, bluish-white beneath; staminate flowers appear early in the spring from buds in the axils of the leaves of the previous season, the pistillate terminal, erect, oblong; cones almost sessile and pendulous, borne on the end of last year's branch, maturing the first season, ovoid, 1.5-2.5 cm. long; wood light, soft, brittle, not durable, difficult to work, splintery but holds a nail well. =Distribution.=--Nova Scotia south to Delaware, west to Minnesota and southeastward through Indiana and eastern Kentucky, thence southward on the mountains to northern Alabama. In Indiana it is not found[4] north of Brown County. It is found in limited numbers at the following places: on a bluff of Bean Blossom Creek in Brown County; on a steep wooded slope on the south side of a small creek about one and a half miles north of Borden in Clark County, and also reported on the bank of Silver Creek between Clark and Floyd Counties; a few trees on the top and sides of the cliffs about one mile east of Taswell in Crawford County; a few trees on the bluff of Guthrie Creek in Jackson County; a few trees along the north fork of the Muscatatuck River between Vernon and North Vernon in Jennings County; a few trees on the south bank of Back Creek near Leesville in Lawrence County; frequent on the banks of Sugar Creek near the "Shades" in Montgomery County; a few trees on the bank of Raccoon Creek in the southern part of Owen County; frequent on the bank of Sugar Creek in Turkey Run State Park in Parke County; a few trees on the banks of Raccoon and Walnut Creeks in Putnam County. Also reported by Beeler[5] as found on a bluff of White River in Morgan County. In all of its stations it is found on sandstone bluffs on the south side of streams, giving it a north or northwest exposure. In a few of the stations there are no small trees, but in Montgomery County along Sugar Creek it is reproducing well. =Remarks.=--Hemlock is of no economic importance in Indiana. The bark is much used in tanning. Hemlock is frequently used for a hedge plant, also as a specimen tree in parks, etc. [Illustration: Plate 6. TSUGA CANADENSIS (Linnæus) Carrière. Hemlock.
