autumn with tones of yellow, orange and brown : flowers i8-22 mm 

 wide, appearing in April and when the leaves are about half 

 grown ; they are produced in simple or subsimple, 3-9-flowered 

 corymbs : pedicels and hypanthium pubescent : sepals lanceolate, 

 4~6 mm long, pubescent, glandular : stamens normally 20, the 

 anthers nearly white : fruit, which ripens and falls in August and 

 early September, subglobose or slightly pyriform, c)-i2 mm thick, 

 red when fully ripe, the flesh firm : nutlets 3-5, about 8 mm long, 

 the lateral surfaces nearly plane and the back usually ridged and 

 grooved : hypostyle occupying two-thirds of the ventral angle. 



Cratcegus rigens inhabits woods and banks of streams throughout north- 

 western and central western Georgia to central eastern and northeastern Alabama. 



The type material, collected at Gadsden, Alabama, and representing flowers 

 {B4206) and fruit (B4206 1 ) from the same tree, is preserved in the Biltmore 

 Herbarium. 



Crataegus amnicola n. sp. 



A tree occasionally 8 m tall with a trunk 2-3 dm in diameter, 

 clothed with dark gray or reddish-brown, scaly bark : branches 

 spreading or ascending, armed with stout, gray or chestnut-brown 

 spines 2>~5 cm l° n g> forming a large spreading top : leaves obovate, 

 oval or ovate, the blades 2-6 cm long, i.5~4 cm wide, acute at the 

 apex, contracted or narrowed at the base into margined, glandless 

 or sparingly glandular petioles 5 mm -2 cm long, the margins sharply 

 and irregularly serrate and incised ; they are slightly pubescent at 

 the time of unfolding on the upper surface, especially along the 

 midrib and lower portions of the veins, paler and less pubescent 

 on the lower surface, the hairs being confined to the midrib and 

 veins, together with their axils, becoming firm or subcoriaceous in 

 texture, bright green and glabrous at maturity, fading in autumn 

 with tones of yellow, orange, red and brown: flowers about i5 mm 

 wide, appearing when the leaves are more than half grown and 

 usually during the last of April or first of May ; they are borne in 

 compound, many-flowered, pubescent corymbs, the lower branches 

 of which are axillary : pedicels and hypanthium pubescent : 

 sepals 4-5 mm long, glandular or pectinately-glandular : stamens 

 20, the anthers nearly white : fruit, which ripens in October, sub- 

 globose, 7-io mm in diameter, red, the flesh firm : nutlets 3-5, 

 about 6 mm long, the lateral surfaces nearly plane and the back either
