Crataegus delucida, n. sp.— Crataegus acutiloba, Sargent, 
RHODORA, iii. 23 in part (1901). 
Leaves ovate to broadly oval, acute, full and rounded or rarely 
cuneate, or on leading shoots truncate or slightly cordate at the 
mostly entire base, finely and often doubly serrate, with glandular 
teeth, and divided into 4 or 5 pairs of short acuminate spreading lat- 
eral lobes ; covered above, early in the season, with short pale hairs ; 
at maturity membranaceous, glabrous, very smooth and light yellow 
on the upper surface, pale on the lower surface, 3.5—4.5 cm. long, 3-4 
cm. wide, or on leading shoots sometimes 6 cm. long and wide, with 
slender yellow midribs and very thin primary veins arching to the 
points of the lobes; petioles slender, nearly terete, 2—2.5 cm. long. 
Flowers about 1.2 cm. in diameter on slender elongated pedicels, in 
compound usually 7—1i2-flowered glabrous thin-branched compact 
corymbs ; calyx-tube broadly obconic, the lobes gradually narrowed 
from broad bases, long, slender, acuminate, entire or occasionally 
furnished with a few minute glandular teeth; stamens 5—10; anthers 
large, light red; styles 3 or 4. Fruit in drooping clusters, oblong, 
full and rounded at the ends, bright scarlet, very lustrous, about 1.2 
cm. in length; calyx small, sessile, with a narrow deep cavity and 
spreading closely appressed lobes, mostly deciduous from the ripe 
fruit; flesh thick, succulent, light yellow; nutlets 3 or 4, full and 
rounded at the ends ridged on the broad back, with a wide rounded 
ridge, 9 mm. long. 
A treelike shrub 3 or 4 m. in height with slender stems covered 
with ashy gray bark, small ascending branches and thin nearly 
straight branchlets, dark green tinged with red when they first appear, 
light orange-red, lustrous and marked by numerous large white 
lenticels during their first season, becoming light gray-brown the

forming small thickets, and in the autumn very conspicuous from the 
abundance of its large bright colored fruits. 
Crataegus demissa, n. sp. Leaves ovate to deltoid, acute, 
broadly cuneate to truncate at the base, sharply doubly serrate, with 
straight teeth tipped with large bright red glands, and slightly divided 
into numerous short acute lateral lobes; when the flowers open
