mostly pubescent beneath, especially along the midrib and largest 

 veins, and when young are more or less pubescent, bright green, 

 firm to subcoriaceous in texture, fading in autumn with tones of 

 yellow, orange and brown : petioles 7 mm -2 cm long, margined, 

 glandular, pubescent, at least when young : flowers about 15mm 

 wide, expanding towards the end of March and when the leaves 

 are about half-grown ; they are solitary or in simple, 2-4-flowered 

 corymbs which terminate short, leafy branchlets or fascicles of 

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

 glandular-serrate, reflexed after anthesis : stamens 15-20, the 

 anthers nearly white : fruit, which ripens and falls in August, 

 pyriform, 9-1 2 mm thick, at maturity yellow or orange-yellow, 

 rarely cheeked with russet-red, the flesh soft : nutlets 3-5, about 

 6 mm long, the lateral surfaces almost plane : hypostyle 4~5 mm long. 



Cratcegus crocea grows in sandy soil at Citra, Florida (type locality). 

 The original specimens, which are deposited in the Biltmore Herbarium, 

 consist of flowers (B4043) and fruit {B404J 2 ) from the same tree. 



Crataegus audens n. sp. 



A large shrub or small tree 2-5 m tall, sometimes with a short 

 trunk i-i.5 dm in diameter, covered with dark gray or brownish,

 brown or gray spines 1. 5-2. 5 cm long : leaves obovate or obovate- 

 cuneiform, the blades 1.5-3.5°™ l° n g> i~3-5 cm wide, abruptly 

 pointed, rounded or lobed at the apex, contracted or narrowed 

 at the base, the margins dentate and shallowly lobed ; they are 

 glabrate and lustrous on the upper surface at maturity, pubescent 

 beneath, especially along the midrib and principal veins, and 

 when young are more or less pubescent on both surfaces, bright 

 green, eventually firm to subcoriaceous in texture, fading in 

 autumn with tones of yellow, orange and brown : petioles 5-1 5 mm 

 long, margined, glandular, pubescent: flowers I5~i6 mm wide, 

 opening early in April and when the leaves are two-thirds or 

 more grown ; they are borne in simple, 2-5-flowered corymbs, or 

 occasionally solitary : pedicels and hypanthium pubescent : sepals 

 4-5 mm long, glandular-serrate, reflexed after anthesis : stamens 20, 

 the anthers almost white : fruit, which ripens and falls in August,
