Crataegus impar n. sp. 



A large shrub 2-4™ tall with many stems and spreading or 

 ascending branches, the largest of which are clothed with dark 

 gray or brownish, rough or scaly bark : spines stout, chestnut- 

 brown or gray, 2-5°™ long : leaves obovate or oval, or on leading 

 shoots, broadly ovate, the blades 2-5 cm long, i.5-4 cm wide, acute 

 at the apex, narrowed or contracted, or on the shoots sometimes 

 rounded at the base, the borders sharply serrate and incised ; they 

 are glabrous, or at the time of unfolding bear a few weak hairs on 

 the base of the midrib on the upper surface, firm to subcoriaceous 

 in texture, deep green, fading with tones of yellow, orange and 

 brown : petioles 7 mm -2 cm long, margined, glandular or remotely 

 glandular : flowers i5-i8 mm wide, opening early in May and when 

 the leaves are almost fully grown ; they are disposed in simple, 

 3-6-flowered corymbs which terminate short leafy branchlets : 

 pedicels and hypanthium glabrous or with several weak hairs : 

 sepals 4-5 mm long, serrate, reflexed after anthesis : stamens vary-

 which ripens and falls in September and October, oval, 10-13™™ 

 thick, red at maturity : nutlets mostly 2-3, 8-io mm long, 4~5 mm 

 measured dorso-ventrally, the lateral surfaces nearly plane : hypo- 

 style about half the length of the nutlet. 



Ci-atcEgiis impar is abundant on a hillside, in clay soil, at Marietta, 

 Georgia (type locality). 



The original specimens, representing flowers (B4288) and fruit (B4288 2 ) 

 from the same individual, are preserved in the Biltmore Herbarium.
