Cratzgus acutifolia, Sargent, Bot. Gazette, xxxi. 217 (1901). 
A nearly glabrous tree, often thirty feet in height, with a trunk eighteen inches in diameter, and 
stout wide-spreading branches forming a symmetrical round-topped rather open head. The bark of the 
trunk is thin, dark reddish brown, and broken into thick closely appressed scales. The branchlets are 
slender, usually straight, marked by oblong pale lenticels, and occasionally armed with scattered thin 
straight chestnut-brown spines which vary from one to nearly two inches in length; during their first year 
they are dark chestnut-brown or orange-brown, and in their second season dull gray-brown. The leaves 
vary from oval to oblong-obovate, and are acute or acuminate or rarely rounded at the apex, cuneate at 
the usually entire base, and finely crenulate-serrate often only above the middle, with gland-tipped teeth ; 
when the flowers open they are nearly fully grown, membranaceous, and lustrous above, with occasional 
short scattered pale caducous hairs along the upper side of the midribs, and at maturity they are thin 
and firm in texture, dark green and lustrous on the upper surface, pale yellow-green on the lower sur- 
face, about an inch and a half long and an inch wide, with slender light yellow midribs compara- 
tively deeply impressed above and four or five pairs of thin slightly raised primary veins ; they are borne 
on slender deeply grooved petioles which are more or less winged above, glandular when they first appear, 
with minute dark caducous glands, and from one quarter to one half of an inch in length. The stipules 
are linear, elongated, glandular-serrate, and caducous. On vigorous leading shoots the leaves are fre- 
quently divided toward the apex into two or three pairs of short acute lobes, and are often three inches 
long and two inches broad. The flowers, which are half an inch in diameter, open about the tenth of 
May and are borne on slender pedicels, in compound many-flowered compact corymbs, with linear 
glandular-serrate bracts and bractlets. The calyx-tube is narrowly obconic and the lobes are lanceolate, 
acuminate, and entire or obscurely and irregularly glandular-serrate, with minute stipitate dark 
glands. There are ten stamens with small pale yellow anthers, and two or three styles. The fruit 
ripens and falls at the end of September and hangs on slender pedicels from one half to three quarters 
of an inch in length, in few-fruited drooping clusters; it is oblong, full and rounded at the ends, 
bright scarlet, marked by occasional large dark dots, and about half an inch long; the calyx-tube is 
prominent, with a broad deep cavity, and the lobes, which are reflexed and closely appressed, are often 
deciduous before the fruit ripens; the flesh is thin, yellow, dry, and mealy. The two or three nutlets 
are thick, prominently ridged on the back, with broad rounded ridges, and about three sixteenths of an 
inch in length. 
Crategus acutifolia inhabits bluffs on the Mississippi River in South St. Louis, Missouri, where 
it grows in open Oak woods and where it appears to have been first collected in May, 1887, by Mr. 
Henry Eggert.’ 
1 Heinrich Karl Daniel Eggert (March 3, 1841) was born at collections in the Harz Mountains and on short journeys to Kreuz- 
Osterwieck in Prussia. He was educated at the seminary in Hal- nach and in Bohemia. Dissatisfied with the small salary of a 
berstadt, and became a teacher in the public schools in the neigh- German school-teacher, Eggert came to America in 1873, and for a 
boring city of Magdeburg. He early became interested in the few months worked on a farm in southern New York. From New 
study of plants, and before leaving Europe he had made botanical York he went to St. Louis, and for nearly twenty years devoted
