thorns: branches flexuous, dark gray, armed with numerous 
dark red or nearly black thorns, 2.5-5cm. long: twig of the 
season glabrous, dark purple-brown, marked with a few pale, 
nearly orbicular lenticels: winter-buds small nearly globular, 
dark red, glabrous. Leaves glabrous, membranaceous, rather 
lax bright green above, scarcely paler beneath, the blades 
ovate, broadly oval or even isodimetric, 4.5-7 cm. long, 4-6.5 
cm. wide, acute or obtuse at the apex, truncate, subcordate 
or on vigorous shoots cordate at the base with a broad open 
sinus, sharply and irregularly glandular serrate, above doub- 
ly serrate or with 3-4 pairs of shallow lateral lobes, entire 
towards the base, 4-6 pairs of prominent veins: petiole slen- 
der, terete, 2-6cm. long, generally two-thirds the length of 
the blades, sometimes slightly margined and with a few 
glands near the base of the leaf. The flowers which expand 
when the leaves are scarcely half grown in small 5-8—flowered 
corymbs, are white, 18-20 mm. wide, and on slender 2—3—brac- 
ted pedicels : petals obovate 8-10 mm, long: styles 3-4, hairy 
at the base, shorter than the 20 stamens: calyx glabrous or 
minutely pubescent, its short divisions glandular serrate or 
laciniate. The fruit is 8-llmm. thick, somewhat longer, 
bright red when mature and persistent until late in winter: 
nutlets 3-4, 5-6 mm. long, about 4mm. thick dorso-ventrally, 
deeply sulcate and ridged on the back. Bracts and stipules 
lanceolate (lunate on vigorous shoots) glandular, bright 
colored, persistent until the flowers expand. 
Crataegus coccinioides occurs along streams and in moist up- 
land woods from southern Illinois to eastern Missouri. It is 
separated from the scarlet thorn by having larger leaves on 
longer petioles and larger fewer flowers. The type material 
is preserved in my herbarium. 
Craiaegus collicola n. sp. A small tree 5-8 meters in height 
with numerous wide-spreading cr horizontal branches form- 
ing an oval or flattened crown, the gray bark of the trunk 
broken into flat, oblong scales and occasionally armed with long 
simple, gray thorns: the nearly straight gray branches armed 
with numerous, slender, gray or purple-brown, 4-8 cm. long
