74 MISSOURI BOTANICAL GARDEN. 
chestnut brown and pubescent in their first season and dark 
reddish brown and nearly glabrous the following year. Mr. 
Bush’s specimens are without thorns. 
Crataegus glabrifolia, n. sp. 
Leaves rhombic to obovate, acute or acuminate, gradually nar- 
rowed to the cuneate entire base, finely often doubly serrate above, 
with straight glandular teeth, and irregularly divided above the middle 
into 2 or 83 pairs of short broad lobes; more than half-grown when the 
flowers open about the Ist of May and {then thin, light yellow-green, 
lustrous and furnished with a few pale hairs above, paler and glabrous 
below, and at maturity thin, yellow-green, glabrous, 4-4.5 cm. long 
and 2.3-3 cm. wide, with slender prominent midribs, and 5 or 6 pairs of 
thin primary veins; petioles slender, narrowly wing-margined at the 
apex, slightly hairy on the upper side early in the season, soon glab- 
rous, sparingly glandular, 1-1.3 cm. in length; leaves on vigorous 
shoots ovate, acuminate, cuneate at the base, deeply divided above 
the middle into acuminate lobes, often 5-6 cm. long and 4.5-5 cm. 
wide, with more prominent midribs and veins. Flowers small, on 
short pedicels, glabrous or furnished with occasional white hairs, in 
crowded mostly 5-7-flowered corymbs; calyx-tube narrowly obconic, 
glabrous, gradually narrowed from the broad base, acuminate, slightly 
glandular, glabrous on the outer surface, villose on the inner surface, 
with a few short hairs, reflexed after anthesis; stamens 10; color of 
the anthers unknown; styles 3-5. Fruit ripening in October, on short 
erect pedicels, in few-fruited clusters, subglobose, angular, greenish 
red marked by numerous small dark dots; flesh dry and mealy; calyx 
little enlarged, with a deep narrow cavity pointed in the bottom, and 
appressed lobes; flesh thin; nutlets 3-5, rounded at the ends, wider at 
the apex than at the base, rounded and ridged on the back, witha 
broad high grooved ridge, 5-7 mm. long and 3-4 mm. wide. 
Grandin, Carter County (B. F. Bush, 9, type, May 6 and 
October 10, 1905; 9A, May 7 and October 11, 1905). 
This species differs so greatly from the other Punctatae 
of southern Missouri in the shape of the leaves, in the 
short pedicels and almost entire absence of any hairy cov- 
ering on the leaves and calyx that I have ventured to de- 
scribe it, although the color of the anthers is unknown and 
I am without information as to the size and habit of the 
plants. Herbarium specimens show that the branchlets are 
glabrous and that the thorns are numerous, slender, nearly 
straight, chestnut brown, lustrous and 3.5-6 cm. in length.
