79 JOURNAL OF THE 
loose compound corymb, the glabrous branches generally 3- 
flowered: pedicels finely pubescent, bearing 1--2 filiform 
glandless bractlets, the bracts of the branches very few, in- 
conspicuous, spathulate, entire, or minutely glandular denticu- 
late: flowers white 1.5 cm. wide: petals orbicular: calyx | 
soft pubescent, the acute divisions entire: stamens 20, scarcely 
longer than the 4--5 styles. Fruit globular, 9--11 mm. thick, 
dark red, glabrous. 
Distinguished from C. coccinea by having more entire leaves, 
and being pubescent. St. Louis County, Missouri. 
Crataegus polybracteata n. sp. A shrub or small flat-topped 
tree with spreading branches. Twigs glabrous, armed with 
stout curved purple-black thorns. Leaves ovate or elliptic, 
the blades 3--6 cm. long, 2-4 cm. wide, glandular serrate, 
with 3--7 shallow lobes, or doubly serrate, acute at the apex, 
acute or obtuse at the entire base, glabrous on both sides: 
petiole slender, 1--2 cm. long, narrowly margined above. 
Inflorescense a 4--10-flowered nearly simple corymb, the 
branches and stout 1--2 cm. long pedicels glandular dot- 
ted, and pubescent with rough spreading hairs: branches and 
pedicels with linear, spathulate, or deeply 3 parted, .5--2 cm. 
long bracts, which are rough hairy, pectinately glandular, 
and persist until after the petals fall. Flowers white, 2--2.5 
cm. wide: stamens about 15: styles 3--4: calyx pubescent 
with a few short, spreading hairs: the divisions 4--6 long, 
pubescent, glandular serrate. The dull red glabrous fruit is 
8--11 mm, in diameter and is borne on strict pedicels. 
This species is related to C. rotundifolia from which it is 
separated by having smaller more simple corymbs, larger 
flowers with hairy pedicels. and large persistent glandular 
bractlets. Ohio to New York. The type is preserved in my 
herbarium.
