1899 and 1900; Tinicum island, Delaware county, B. H. Smith, 
1900. 
To be distinguished from the related Crataegus Crus-galii by its oblong 
usually pointed leaves with veins raised and prominent on the lower surface, 
by its short infrequent spines, by the habitual appearance of the flowers ten 
days before those of that species open in the same region, and by the red 
juicy flesh of the fruit. First noticed in October 1898, by Mr. W. N. Canby 
of Wilmington, Delaware, who permits the association of his name with this 
handsome tree. 
Crataegus Peoriensis, n. sp.—Leaves obovate, short-pointed or 
occasionally rounded and sometimes slightly irregularly lobed at 
the broad apex, gradually narrowed below, sharply and often 
doubly glandular-serrate usually only above the middle, glab- 
rous with the exception of a few scattered pale hairs néar the 
base of the upper surface of the midribs, thick and firm, with 
four or five pairs of thin primary veins raised and conspicuous 
below, deeply impressed above and running very obliquely from 
the slender midrib to the end of the leaf, dark green and very 
lustrous on the upper surface, pale on the lower surface, bright 
bronze color as they unfold, % to 2 in. long, 3% to I in. wide, 
and on vigorous leading shoots frequently a third larger and 
occasionally laterally lobed; petioles broad, deeply grooved, 
more or less winged and slightly glandular above the middle, 
and covered early in the season with short white scattered hairs ; 
stipules glandular, linear-lanceolate, or on vigorous shoots 
lunate and ¥% to I in. long. Flowers cup-shaped, % in. in 
diameter when fully expanded, in broad loose slender-stemmed 
many-flowered corymbs, their bracts and bractlets linear, conspic- 
uously glandular, caducous; calyx glabrous, the cup deep and 
narrow; calyx-lobes narrow, acuminate, entire or irregularly 
glandular-serrate with minute stalked dark red glands, pubescent 
below the middle on the upper surface, spreading nearly at right 
angles to the cup when the flowers open, persistent on the fruit ; 
stamens ten; filaments elongated, slender; anthers small, rose- 
color; styles usually two or three. Fruit oblong to obovate, 
full and rounded at the ends, slightly depressed at the insertion 
of the peduncle, bright scarlet, % to 34 in. long, with thick
