Crataegus alma n. sp. 



A shrub 2-4™ tall with dark gray, either smooth or scaly bark 

 and spreading or ascending branches which are sometimes armed 

 with spines 2-3 cm long : leaves ovate, oval or obovate, the blades 

 2-6 cm long, i.5~4 cm wide, pointed at the apex, either rounded, 

 contracted or narrowed at the base, the borders serrate and 

 incised ; they are glabrous, firm in texture, bright green, fading 

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

 j_ 2 cm long, margined: flowers 15-20™™ wide, opening from the 

 middle to the last of April ; they are produced in glabrous, 

 glandular-bracteate, 3-7-flowered corymbs which terminate short, 

 leafy branchlets : pedicels and hypanthium glabrous : sepals 

 glandular-serrate or subentire, about 4 mm long, reflexed after 

 anthesis : fruit, which ripens in October, subglobose, io-i2 mm 

 in diameter, red when fully ripe, the flesh firm : nutlets 3-5, 

 7-8 mm long, the lateral surfaces plane : hypostyle about half the 

 length of the nutlet. 



Cratcegus alma was discovered on the gravelly hills near Meridian, Missis- 

 sippi (type locality), and is abundantly represented in that region. 



The type material {BJ14J) is preserved in the Biltmore Herbarium.

 almost fully grown ; they are disposed in simple, 3-7-flowered 

 corymbs which terminate short, leafy branchlets : pedicels 5 mm -i em 

 long, glabrous, as is the hypanthium : sepals about 4 mra long, 

 glandular-serrate, reflexed after anthesis : stamens 20, the anthers 

 dark purple : fruit, which ripens and falls in September and 

 October, globose or subglobose, y-g mm in diameter, red when
