branches forming a wide, symmetrical crown: leaves oval, elliptic 

 or oblong, sometimes obovate or oblong-cuneiform, the blades 

 2 _6 cm long, i~4 cm wide, mostly pointed at the apex, contracted or 

 narrowed at the base, the borders serrate, mostly above the mid- 

 dle ; they are dark green, lustrous and glabrate on the upper sur- 

 face at maturity, pale or whitened and pubescent beneath, the 

 pubescence dense and more persistent along the midrib and prin- 

 cipal veins, and when young are pubescent on both surfaces, 

 eventually firm to subcoriaceous in texture, fading in autumn with 

 tones of yellow, orange and brown : petioles 2— io mm long, pubes- 

 cent : flowers, which open early in April and when the leaves are 

 two-thirds or more grown, produced in hirsute-pubescent, com- 

 pound corymbs : pedicels and hypanthium hirsute-pubescent : 

 sepals 3~4 mm long, slightly serrate or entire, spreading or reflexed 

 after anthesis : stamens 10-14, the anthers purple : fruit, which 

 ripens in August, oblong, 8-1 2 mm thick, io-i4 mm long, pale yellow 

 at maturity, the flesh soft and edible : nutlets solitary or in pairs, 

 about 7 mm long, the ventral surface nearly plane : hypostyle about 

 4 mm long. 



Cratcegus albicera often forms a fine symmetrical tree, and is common in the 

 region about Opelousas, Louisiana (type locality). 



The type material is preserved in the Biltmore Herbarium.
