2 or 3. Fruit in drooping few-fruited clusters, oblong, full 
and rounded at the ends, bright scarlet, marked by few large 
dark lenticels, about % in. long; calyx-tube prominent with 
a broad deep cavity, the lobes closely appressed, often decidu- 
ous before the maturity of the fruit; flesh thin, yellow, dry and 
mealy; nutlets 2 or 3, broad, prominently ridged on the back 
with broad rounded ridges, about ,%, in. long. 
A tree 25 to 30 ft. in height with a trunk 8 or Io in. in 
diameter, and wide-spreading branches forming a broad sym- 
metrical rather flat-topped head and slender nearly straight 
branchlets marked by oblong pale lenticels, dark chestnut-brown 
or orange-brown and lustrous during their first year, becoming 
dull gray-brown during their second season, and slightly armed 
with few slender straight chestnut-brown spines from I to nearly 
2 in. in length. 
Flowers early in May. Fruit ripens toward the end of 
September. 
Open oak woods near the bank of the Mississippi river at 
Carondelet in South St. Louis, Missouri. First collected in May 
1887 by H. Eggert, and in September 1900 by Eggert, Norton, and 
Sargent. 
This is one of several forms which have been usually confounded with 
Crataegus Crus-galli of Linnaeus, but which can probably best be separated 
from that species. From Crataegus Crus-galli as limited by Linnaeus and 
Aiton, and now universally recognized, it differs in its thin usually acute or 
acuminate leaves with comparatively prominent veins, in its smaller flowers, 
much smaller early-ripening scarlet fruit, and in its more slender branchlets 
only sparingly armed with much more slender spines. 
/ Crataegus erecta, n. sp.—Glabrous. Leaves broadly oval to 
obovate, or on leading shoots nearly orbicular, acute and short- 
pointed at the apex, cuneate and entire at the base, finely crenu- 
late-serrate above, or on vigorous shoots coarsely dentate with 
broad nearly straight gland-tipped teeth, thin, dull green and 
nearly fully grown when the flowers open, and at maturity thin 
but firm in texture, dark dull green on the upper surface, pale on 
the lower surface, 1% to 2 in. long, 1 to 1% in. wide, and on 
leading shoots sometimes 3 in. long and 2% in.. wide, with
