FLABELLATAE. 
CRATAEGUS FLABELLATA, Spach, La Tortue, /. G. Jack, May 
and October, 1900, Caughnawaga, May and September, 1900. 
First described from plants cultivated at the Jardin des Plantes in 
Paris and known only in the descendants of these plants in Euro- 
pean gardens, Crataegus flabellata appears to have been first dis- 
covered in a wild state by Mr. Jack. A tall shrub, well distinguished 
by the long acute spreading lobes of the leaves, by the large flowers 
with 20 stamens and pink anthers, and by the small oblong late. 
ripening fruit. 
Crataegus densiflora. Leaves oval to ovate, acute or short- 
pointed at the apex, broadly cuneate or occasionally rounded 
at the base, laciniately cut above the middle into numerous short 
narrow acuminate spreading lobes, crenulate-serrate, the small teeth 
tipped with bright red glands; covered in early spring on the upper 
surface with soft white caducous hairs, glabrous on the lower 
surface, and at maturity thin but firm in texture, dark dull green and 
smooth above, pale yellow-green below, 2 to 3 in. long, 14 to 2 in. 
wide, with slender midribs only slightly impressed above and thin 
primary veins arching to the points of the lobes; petioles slender, 
glandular, more or less winged above on vigorous leading shoots, 
from 1 to 14 in. long; stipules narrowly obovate to linear lanceo- 
late, finely glandular-serrate, 14 in. long, caducous. Flowers 4 in. 
in diameter, on slender elongated pedicels in very compact narrow 
thin-branched tomentose or villose many-flowered cymes; bracts 
and bractlets finely glandular-serrate, caducous; calyx-tube narrowly 
obconic, glabrous, the lobes lanceolate, glandular with bright red 
glands, glabrous on the outer surface, densely villose on the inner 
surface, reflexed after anthesis; stamens usually 10, sometimes 5 to 10; 
filaments slender; anthers small, pale red or pink; styles 3 or 4, 
surrounded at the base by a thick ring of hoary tomentum. Fruit 
in erect slightly villose few fruited clusters, oblong, dark crimson or
