5-15 cm. long, on stalks generally -about 0.5 cm. long, the terminal one 

 on a stalk 2-4 times as long, leaflets general!}' ovate, ovate-oblong, or 

 oblong to narrow-oblong, generally with a narrowed base, sometimes 

 rounded and oblique, short or long acuminate at the apex, margins 

 sometimes entire, generally entire near the base, the remainder more or 

 less serrated with shallow teeth, dark green and smooth above, a lighter 

 green beneath and more or less densely pubescent all over the lower 

 surface, especially on the midrib and veins; calyx persistent, about 1 mm. 

 long; fruit can not be distinguished from the preceding. 



Distribution. Quebec tc Manitoba, and south to Florida. Found 

 sparingly in all parts of Indiana. It is usually found in low ground, but 

 frequently on bluffs, and flood plain banks. 



Remarks. This species is not commonly separated from the white 

 ash group, but in books it is known as the red ash. This is the common 

 name that should be applied to this form. 



This species is not usually separated from the preceding, but it is 

 easily distinguished from it by its pubescent twigs. It can be distin- 

 guished from the next by its smaller twigs, smaller calyx and smaller 

 fruit. 



The wood is similar to that of the white ash, and the cut is usually 

 sold as that species. In mechanical qualities it is on a par with the 

 green ash. 



5. Fraxinus profunda Bush. SWELLTBUTT 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 

 J^ 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 %-% its length, sometimes almost 

 terminal. 



Distribution. Virginia, Indiana and Missouri, and south to 

 Florida. In Indiana the distribution has not been determined. It is
