54 BULLETIN 119, U. S, DEPARTMENT OF AGRICULTUEE. 



Leaves oval or oblong-oval, mostly 5 to 8 cm. long, 2 to- 3.6 cm. 

 broad, narrowed toward the base, acute or acuminate at the apex, 

 obscurely pubescent above, pubescent below, sometimes strongly so, 

 very rarely glabrous except along the midvein; petioles 5 to 9 mm. 

 long, pubescent. Flowers appearing in March or April, 12 to 15 mm. 

 broad; pedicels and calyx usually pubescent, sometimes obscurely 

 so. Fruit similar to the species; stone oval and usually pointed at 

 both ends, about 13 mm. long. 



Prunus umhellata injucunda ranges from the extreme southwestern 

 part of North Carolina through the hill country of Georgia to Missis- 

 sippi, and probably merges imperceptibly into the subspecies P. 

 umbellata tarda. 



Prunus umhellata injucunda was described as a species from ' ' sandy 

 soil on the granite districts from Stone Mountain, Ga./' and the type 

 collected by John K. Small, July 7, 1893, is in the herbarium of the 

 New York Botanical Garden. This represents a form with extremely 

 pubescent foHage and branchlets. Prunus mitis was described from 

 specimens collected at Auburn, Lee County, Ala., March 27 and May 

 20, 1900, by F. S. and Esther S. Earle, No. 27, and type material is 

 preserved in the Biltmore Herbarium. This form has less pubescent 

 foliage and glabrous twigs, but numerous specimens show various 

 intermediate stages, some from the same region on sandy soil having 

 glabrous twigs while those on clay soil were strongly pubescent, the 

 trees differing in no other character. 



Prunus Umbellata Tarda (Sargent) W. F. Wight. 

 Prunus tarda Sargent, 1902, in Bot. Gaz., v. 33, No. 2, p. 108. 



Leaves oblong-oval or rarely obovate, narrowed at the base, acute 

 or shortly acuminate at the apex, 4 to 8 cm. long, 1.5 to 3.5 cm. 

 broad, dull yellowish green, finely and obscurely pubescent or gla- 

 brate a,bove, pale and somewhat pubescent below, at least along the 

 midrib and prominent lateral veins, the margins serrate with acute 

 somewhat incurved teeth; petioles tomentose. Flowers appearing 

 in April, about 12 mm. broad; pedicels glabrous; calyx tube spar- 

 ingly pubescent without, more strongly hairy withm; petals oblong- 

 obovate, 5 to 6 mm. long. Fruit subglobose or slightly oval, 10 to 15 

 mm. in diameter, yellow, purple, red, or dark blue in color, with a 

 bloom, ripening in October and November; stone as in the preceding. 



The tree is 18 to 25 feet high, with light reddish brown bark exfoH- 

 ating in small platelike scales, that of the branchlets somewhat lus- 

 trous. Prunus umbellata tarda is very similar to the species, but 

 may be distinguished by its lighter bark, later ripening fruit, and 

 more oblong stone. The type specimens, collected on April 19, 1901,
