veins on both surfaces, bright green, firm in texture, fading in 

 autumn with tones of yellow, brown and orange : petioles 5-i5 mm 

 long, margined, glandular, pubescent, at least when young : flow- 

 ers i5~2o mm wide, opening about the first of April and when the 

 leaves are two-thirds grown ; they are produced in simple, 3-5- 

 nowered corymbs which terminate short, leafy branchlets : pedicels 

 and hypanthium tomentose-pubescent : sepals 4~5 mm long, serrate, 

 glandular, reflexed after anthesis : stamens 20, the anthers pale 

 purple : fruit, which ripens the last of August and early in Sep- 

 tember, globose, i2-i5 mm in diameter, red at maturity, the flesh 

 orange, succulent : nutlets 3-5, 7-8 mm long, the lateral surfaces 

 nearly plane : hypostyle 4-5 mm long. 



Cratczgus adunca grows in sandy woods at Tallahassee, Florida (type 

 locality) . 



The type specimens, representing flowers (H4063) and fruit (H^g^i) from the 

 same individual, are preserved in the Biltmore Herbarium.

 corymbs which terminate short, leafy branchlets : pedicels 1-2. 5 cm 

 long, like the hypanthium, pubescent : sepals 4-5 mm long, serrate, 

 glandular, reflexed after anthesis : stamens 20, the anthers nearly 

 yellow : fruit, which ripens and falls the last of August and early 

 in September, subglobose or slightly pyriform, io-i2 mm thick,
