 pubescent, especially along the midrib and principal veins, and 

 when young are clothed with pale, short hairs on both surfaces, 

 thin to firm in texture, fading in autumn with tones of yellow, 

 orange and brown: petioles 1-2. 5 cm long, margined, glandular, 

 pubescent : flowers about 2 cm wide, expanding about the 20th of 

 May and when the leaves are almost fully grown ; they are dis- 

 posed in simple, 3-7-flowered corymbs which terminate short, 

 leafy branchlets of the present season's growth : pedicels and 

 hypanthium pubescent : sepals 4-5""" long, glandular-serrate, 

 reflexed after anthesis : stamens 20, the anthers light yellow : 

 fruit, which ripens and falls in September, oblong or obovate, 

 9-i2 mm thick, io-i4 mm long, at maturity red or ruddy : nutlets 3-5, 

 about 8 mm long, the lateral surfaces nearly plane : hypostyle 3-4 mm 

 long. 



Cratczgus craytoni grows on the bluffs and banks of the French Broad river, 

 three miles south of Marshall, Madison county, North Carolina (type locality), 

 where it was first found and collected by Mr. F. M. Crayton, of Biltmore, N. C, 

 and for whom the species is named. 



The type specimens, representing both flowers and fruit from the same bush, 

 are preserved in the Biltmore Herbarium.
