io-i5 mm in diameter, at maturity red, the flesh orange or orange- 

 yellow, succulent: nutlets 3-5, 7-9™™ long, 3. 5— 5 mm measured 

 dorso-ventrally, the lateral surfaces nearly plane : hypostyle 5-6 mm 

 long. 



Crataegus abdita is abundant in woods, mostly in sandy soil, near River 

 Junction, Florida (type locality). 



The type specimens, consisting of flowers {B2082) and fruit (H4Q70) from the 

 same tree, are preserved in the Biltmore Herbarium. 



Crataegus exilis n. sp. 



A large shrub or small tree 3-6 111 tall with a trunk sometimes 

 i-i.5 dm in diameter, clothed with dark gray or brownish, either 

 rough or scaly bark, the spreading branches, which are usually 

 armed with stout spines i-2 cm long, forming an irregular, oval or 

 flat-topped crown : leaves obovate, oval or elliptic, or on the 

 shoots rhombic-ovate, the blades i.5-4 cm long, 1-3. 5 cm wide, acute 

 or abruptly pointed at the apex, cuneate or contracted, rarely 

 rounded at the base, the borders serrate and incised, or on lead- 

 ing shoots deeply lobed ; they are glabrous at maturity, and when 

 young are pubescent, especially on the midrib and bases of the 

 principal veins above and in their axils beneath, firm to subcoria- 

 ceous in texture, bright green, fading in autumn with tones of 

 yellow, brown and orange : petioles 5 mm -i.5 cm long, margined, 

 minutely glandular, pubescent, at least when young : flowers 

 about I5 mm wide, opening about the first of April and when the 

 leaves are about one-fourth grown; they are disposed in simple or 

 subsimple, 3-7-flowered corymbs, the lower branches of which 

 arise from the axils of leaves : pedicels and hypanthium pilose- 

 pubescent : sepals 3-4""" long, lanceolate, serrate or entire, glan- 

 dular, reflexed after anthesis : stamens 20, the anthers pale yel- 

 low : fruit, which ripens and falls in September, globose or sub- 

 globose, S~7 mm wide, at maturity red or ruddy, the flesh thin : 

 nutlets 3-5, 4-5 mm long, the lateral surfaces nearly plane : hypo- 

 style about 3 mm long. 



Crataegus exilis was collected at Albany, Georgia (type locality), growing in 

 sandy soil and along the banks of the river. 



The type specimens, flowers (B4093) and fruit (B4093 2 ) from the same tree 

 are preserved in the Biltmore Herbarium.
