on slender glabrous purple pedicels f'-l \' long, in 4-7-flowered clusters; calyx- tube purple 

 and glabrous, the lobes glabrous on the outer surface, slightly longer than the tube; petals 

 suborbicular or broadly ovate, abruptly contracted below, about f ' wide, often erose- 

 denticulate; stamens about one third shorter than the petals; styles 5, slightly longer than 

 the stamens, villose below the middle. Fruit on slender pedicels about f ' in length, de- 

 pressed globose, slightly angled, distinctly ribbed at the deeply impressed apex, about lj' 

 high and l' in diameter, with a deep basal cavity; seed obo void-oblong, about ' long. 



A tree, 18-25 high, with a short trunk rarely 1 in diameter, spreading branches often 

 armed with stout straight spines up to 1^' in length, and glabrous purple branchlets, be- 

 coming purple-brown and slightly lustrous at the end of their first season, dull red-brown 

 in their second year, and ultimately grayish brown. Winter-buds ovoid or oblong-ovoid, 

 acute, glabrous, dark purple-brown up to \ r in length. 



Distribution. A common Crab Apple in the valleys of western North Carolina at al- 

 titudes of 2000-3500; near Biltmore, Buncombe County, Dillsboro, Jackson County, and 

 Highlands, Macon County. 



2. Malus glaucescens Rehd. Crab Apple. 



Leaves triangular-ovate or ovate, acute, short-acuminate or rounded at apex, truncate 

 or rounded at base, those of flowering branchlets more or less lobed and' coarsely serrate 

 with abruptly acuminate teeth, their lobes triangular, broad-ovate and abruptly acumi-

nate, those of the lowest pair usually the longest, bronze color and covered with thin floccose 

 tomentum when they unfold, soon glabrous, dull yellowish green above, glaucescent below, 

 l|'-3^' long and 1 |'-3' wide, with 4-7 pairs of prominent primary veins; turning yellow or 

 dark purple and falling early in the autumn; petioles slender, slightly villose at first, soon 

 glabrous, l|'-3' in length; stipules filiform, purple, glabrous or slightly villose, about \' 

 long; leaves at the end of vigorous shoots broad-ovate, acuminate, rounded or slightly cor- 

 date at base, often deeply lobed, 3'-3|' long, 3' wide, with petioles l|'-2' in length. 

 Flowers 1|'-1|' in diameter, on slender glabrous pedicels, f'-l|' in length, in usually 

 5-7-flowered clusters, calyx-tube coated with floccose caducous pubescence or glabrous, 

 slightly shorter than the long-acuminate lobes densely tomentose on the inner surface; 

 petals oval, abruptly contracted below into a long claw, white or rose color, f '-f ' wide; 

 stamens about one third shorter than the petals; styles 5, about as long as the stamens, 

 densely villose below and united at base for about one fourth of their length. Fruit
