gined, glandular, pubescent, at least when young: flowers i2-i6 mm

 corymbs which terminate short leafy branchlets or fascicles of 

 leaves : pedicels and hypanthium tomentose : sepals 3-4 mm long, 

 glandular-serrate, reflexed after anthesis : fruit, which ripens and 

 falls in August, pyriform, 8-1 i mm thick, at maturity yellow or 

 orange-yellow, cheeked or flushed with red, the flesh soft : nutlets 

 mostly 3-4, 6-7 mm long, the lateral surfaces nearly plane : hypo- 

 style 4-5 mm long. 



Cratczgus villaris is quite common in sandy soil at Citra, Florida (type 

 locality). 



The type specimens, representing flowers {B4042) and fruit (B4042 2 ) from

 pubescent on both surfaces, eventually bright green, firm to sub- 

 coriaceous in texture, fading with tones of yellow, orange and 

 brown : petioles 5-i5 mm long, margined, glandular, pubescent, at

 end of March and when the leaves are about one-third grown ; 

 they are solitary or in simple, 2-4-flowered corymbs which termi- 

 nate short, leafy branchlets or fascicles of leaves : pedicels and 

 hypanthium tomentose : sepals 3~4 mm long, serrate, glandular, 

 reflexed after anthesis : stamens 20, the anthers light yellow: fruit, 

 which ripens in August, pyriform, 6-9 mm thick, at maturity orange- 

 red or orange with red cheeks, the flesh very thin : nutlets usually 

 3-4, 6-7 mm long, the lateral surfaces nearly plane : hypostyle 4-5 mm 

 long, 2-2. 5 mm wide near the top of each lateral surface.
