Crataegus macra n. sp. 



A small tree with a low, flat, spreading top, or a large, spread- 

 ing shrub 2-5 m tall with one or more stems covered with dark 

 gray or brownish scaly bark, the branches freely armed with stout, 

 chestnut-brown or gray spines 2.5~5.5 cm long, or on the largest 

 branches and stems the thorns are usually compound and some- 

 times i-i.5 dm long : leaves cuneate or oblong- or obovate-cunei- 

 form, the blades 2~5 cm long, 8 mm -2 cm wide, either rounded or 

 pointed at the apex, cuneate at the base, the borders serrate above 

 the middle ; they are glabrous and lustrous on the upper surface, 

 pale beneath, firm to subcoriaceous in texture, fading in autumn 

 with tones of yellow, orange and brown : petioles 3-io mm long, 

 margined: flowers about i2 mm wide, opening about the first of 

 May and when the leaves are two-thirds grown ; they are pro- 

 duced in small, short, compound, glabrous corymbs, the lowest 

 branches of which are axillary: pedicels and hypanthium gla- 

 brous : sepals 3-4. 5 mm long, mostly entire, spreading or reflexed 

 after anthesis : stamens about 10, the anthers purplish : fruit, 

 which ripens in September and October, subglobose or oval, 5~8 mm 

 broad, red at maturity : nutlets 1-3, 6-7 mm long, the lateral or 

 ventral surfaces nearly plane : hypostyle 3-4 mm long. 



Cratcegus macra is abundant in the flat woods of northwestern Georgia, 

 especially at Rome (type locality). 



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

 represent both flowers (B2230) and fruit {B22^o i ) from the same tree. 



Crataegus regalis n. sp. 



A tree sometimes io m tall with a trunk 2~3 dm in diameter, cov- 

 ered with ashy-gray or brownish scaly bark, the ascending and 

 spreading branches often armed with chestnut-brown or gray 

 spines : leaves oval, broadly oval or elliptic, the blades 3-8 cm long, 

 x -5 _ 5 cm wide, acute or acuminate at the apex, contracted or 

 broadly cuneate at the base, the borders serrate and on leading 

 shoots often incised ; they are glabrous, or when young bear a few 

 weak hairs along the midrib and on the upper surface, bright 

 green and lustrous above, pale beneath, firm to subcoriaceous in 

 texture, fading in autumn with tones of yellow, orange and brown: 

 petioles 5-i5 mm long, margined: flowers 1 2-1 4 m J? wide, opening
