Crataegus valida n. sp. 



A large shrub or small tree 2-5 111 tall with a short trunk 

 i-i.sjdm i n diameter, clothed with gray or brownish rough or scaly 

 bark, the stout, spreading or ascending branches frequently armed 

 with chestnut-brown or gray spines i-2 cm long : leaves obovate, 

 oval or orbicular, the blades 2-5°" long, 1.5-5^ broad, or larger 

 and broader than long on the shoots, rounded or abruptly pointed 

 at the apex, contracted or rounded, or on strong shoots truncate 

 or subcordate at the base, the margins irregularly dentate ; they 

 are glabrous or very nearly so at maturity, and when young bear a 

 few weak hairs along the midrib and principal veins, especially on 

 the upper surface, firm to subcoriaceous in texture, bright green, 

 fading in autumn with tones of yellow, brown and orange : 

 petioles 5-i5 mm long, margined, glandular, pubescent : flowers 

 1 5-20 mm wide, opening after the middle of April and when the 

 leaves are about one-third grown ; they are produced in simple, 

 3-5-flowered corymbs, which terminate short leafy branchlets : 

 pedicels and hypanthium sparsely pilose-pubescent : sepals 3-4 mm 

 long, i.5-2 mm wide, serrate, glandular, reflexed after anthesis : 

 stamens 20, the anthers purple : fruit, which ripens in September 

 and October, subglobose, i2-i5 mm thick, the cavity 4-6 mm wide: 

 nutlets 3-5, 8-g mm long, 4-5 mm measured dorso-ventrally, the 

 lateral surfaces nearly plane : hypostyle about 5 mm long. 



Cratcegus valida grows on a rocky hill at Rockmart, Georgia (type local- 

 ity), and is peculiar on account of its stiff, stout branches and broad leaves. 



The original specimens, which are preserved in the Biltmore Herbarium, 

 represent both flowers (B^/jj) and fruit from the same tree.
