=5. Fraxinus profúnda= Bush. Swell-butt Ash. Plate 128. Medium or large trees with fissured bark similar to the white ash; twigs robust and velvety pubescent at least while young; leaves generally 2-4 dm. long, rachis densely pubescent, rarely almost smooth; leaflets 5-9, generally 7, on stalks 0.5-1 cm. long, the terminal one on a stalk 2-4 times as long, leaflets ovate, narrow-ovate to narrow-oblong, narrowed or rounded and oblique at the base, short or long taper-pointed at the apex, margins entire, rarely with a few short teeth, dark green and smooth above, a lighter green and densely pubescent beneath, rarely somewhat smooth; calyx persistent, generally 4-5 mm. long, rarely as short as 3 mm.; fruit ripening in September and October, linear, generally 4-6 cm. long, variable in size and shape, body about 1/3 the length of the samara, compressed or flattened and gradually narrowed to the base, the striations on the face of the body not prominent and usually not distinct the full length of the body, samara often unilateral or somewhat falcate; wings notched or merely rounded at the apex, decurrent on the body 1/4-1/2 its length, sometimes almost terminal. [Illustration: Plate 128. FRAXINUS PROFUNDA Bush. Swell-butt or Pumpkin Ash. (× 1/2.)] =Distribution.=--Virginia, Indiana and Missouri, and south to Florida. In Indiana the distribution has not been determined. It is a common to an infrequent tree of the river sloughs and cypress swamps of the southwestern counties. Authentic specimens are at hand from Knox, Gibson, Posey, Perry, Bartholomew, Jackson, Marion and Daviess Counties, and specimens from Hamilton, Tipton and Starke Counties, I doubtfully refer to this species. The preferred habitat of this species is inundated swamps, and when it grows in such situations it generally develops a base swollen to a point somewhat above the water level. In Bartholomew County it was found associated with the cow oak, and the trunk resembled the white ash. =Remarks.=--This species is known by authors and commercially as pumpkin ash. The wood is similar to white ash but is inferior to that species. On account of its habitat this species was little cut until the past few years when ash became scarce. During the past few years most of the deep river and cypress swamps have been invaded and all of the ash cut.
