54 BULLETIN 179, U. S. DEPARTMENT OF AGRICULTURE. 
Leaves oval or oblong-oval, mostly 5 to 8 cm. long, 2 to 3.5 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 umbellata injucunda ranges from the extreme southwestern | 
part of North Carolina through the hill country of Georgia to Missis- | 
sippi, and probably merges imperceptibly imto the subspecies P._ 
umbellata tarda. | 
Prunus umbellata 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 folhage 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 Tarpa (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 em. long, 1.5 to 3.5 cm. 
broad, dull yellowish green, finely and obscurely pubescent or gla-_ 
brate above, 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 within; 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 exfoli- | 
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, |
