Crataegus annosa n. sp. 



A tree sometimes 8 m tall with a trunk 3 dm in diameter clothed 

 with dark, rough or rimose bark, the spreading or ascending 

 branches frequently armed with stout chestnut-brown or gray 

 spines 2-3 cm long : leaves obovate, oval or oblanceolate, or on 

 leading shoots orbicular, the blades 2-4. 5 cm long, i-4 cm wide, 

 mostly pointed at the apex, cuneate or more abruptly contracted, 

 or on strong shoots rounded at the base, the borders dentate 

 and glandular, mostly with several sharp, tooth-like lobes ; they 

 are glabrous or glabrate at maturity and when young are slightly 

 pubescent on both surfaces, especially along the midrib and 

 largest veins, firm in texture, bright green, fading in autumn 

 with tones of yellow, orange and brown : petioles 5^-2™ long, 

 glandular, margined, pubescent, at least when young : flowers 

 i5-20 mm wide, opening early in April and when the leaves are 

 about half grown ; they are disposed in simple, 3-5-flowered 

 corymbs that terminate short, leafy branchlets : pedicels and 

 hypanthium pubescent : sepals 3-4. 5 mm long, serrate, glandular, 

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

 fruit, which ripens and falls the last of August and early in 

 September, subglobose or oval, io-i2 mm in diameter, orange-red 

 or red and orange when ripe, the flesh soft : nutlets 3-5, 7-8 mm 

 long, the lateral surfaces nearly plane : hypostyle occupying about 

 two-thirds of the ventral angle. 



Cratcegus annosa under favorable conditions develops into one of the larg- 

 est trees of the " flava group," and is abundantly represented in eastern 

 central Alabama, where, at Phoenix City (type locality), trees of great age 

 sometimes attain remarkable proportions. 



The type specimens, consisting of flowers (Bfroj) and fruit (B4/0J 2 ) from 

 the same tree, are preserved in the Biltmore Herbarium. 



Crataegus calva n. sp. 



A shrub 2-4 111 tall with rough bark and ascending or spreading 

 branches which are sometimes armed with stout chestnut-brown 

 or gray spines 1-1.5°™ l° n g : leaves obovate, oval or elliptic, the 

 blades i.5-3 cm long, 7mm_ 2 cm broad, mostly pointed at the apex, 

 narrowed or contracted, or occasionally rounded at the base, the 

 borders dentate, glandular and usually with several tooth-like 

 lobes ; they are glabrous when fully grown and when young
