TREES OF NORTH AMERICA 



white hairs caducous except from the midrib and at maturity glabrous; dark yellow-green, 

 lustrous, and slightly rugulose on the upper surface, lighter on the lower surface, 2|'-3 long 

 and 1|'-2|' wide, with 5-7 pairs of prominent primary veins; petioles slender, villose, often 

 becoming nearly glabrous, I'-l^' in length; on vigorous shoots often broad-ovate and 

 lobed with short triangular lobes sometimes 4' long and nearly as wide. Flowers about 

 \y in diameter, on glabrous pedicels l%'-% long, in 3-6-flowered clusters; calyx-tube 

 glabrous or rarely pubescent (var. Hoopesii Rehd.), the lobes lanceolate, acuminate, 

 longer than the tube, glabrous on the outer surface, densely tomentose on the inner 

 surface; petals orbicular-obovate, usually irregularly incisely dentate and abruptly con- 

 tracted at base into a short claw, slightly villose on the inner surface near the base, \' to

nearly 1' wide; stamens slightly shorter than the petals; styles 5, somewhat shorter than 

 the stamens, 'villose below the middle and united below for one third their length. Fruit 

 on slender pedicels, \\'-\\ r in length, depressed globose with a deep cavity at base and 

 apex, l^'-lf high and 2'-2|' wide; seeds oblong-obovoid, about long. 



A tree, 18-20 high, with a trunk 4' or 5' in diameter, spreading unarmed branches, and 

 branchlets clothed when they first appear with thin villose tomentum, becoming by the 

 end of their first year glabrous, brown or purple-brown and lustrous, dull brown in their 

 second season, and ultimately grayish brown. Winter-buds ovoid, acute, glabrous except 

 on the villose margins of the purplish brown scales, about \' long. 



Distribution. Near Franklin, Macon County, North Carolina; Mercer Springs, Mercer 

 County, West Virginia; near Olympia, Bath County, Kentucky; Youngstown, Mahoning 

 County, Ohio (R. E. Horsey}. 



5. Malus lancifolia Rehd. Crab Apple. 



Leaves ovate-lanceolate to oblong-lanceolate, acute or short-acuminate at apex, rounded 

 or broad-cuneate at base, finely or coarsely doubly serrate with short or occasionally with 

 larger teeth pointing forward, covered with thin floccose tomentum when they unfold, 

 soon glabrous, bright yellow-green, l'-3' long, '-!' wide, with 8-10 pairs of veins; petioles 

 slender, slightly villose at first, soon glabrous, '-1' in length; leaves on vigorous shoots 

 ovate or oblong-ovate, slightly lobed, more densely pubescent below, 2|'-3f ' long, 2'-2|' 

 wide, with a thin midrib and 4-7 pairs of veins slightly villose through the season, and 

 stouter petioles. Flowers li'-l|' in diameter, in 3-6-flowered clusters, on slender glabrous 

 pedicels about 1|' in length; calyx glabrous, the lobes longer than the tube, oblong-lanceo- 

 late, glabrous on the outer surface, coated with villose tomentum on the inner surface;
