the last of April and when the leaves are almost fully grown ; 

 they are produced in glabrous, compound, many-flowered corymbs, 

 the lowest branches of which arise from the axils of leaves : pedi- 

 cels and hypanthium glabrous : sepals 4-5™™ long, linear-lanceo- 

 late, entire or remotely serrate, spreading or reflexed after anthe- 

 sis : stamens about 10, the anthers yellow : fruit, which ripens in 

 September and October, oblong, about 8 mm thick and i cm long : 

 nutlets mostly 2-3, 7-8 mm long, the lateral or ventral surfaces 

 nearly plane : hypostyle 5~6 mm long. 



Cratcsgus regalis often forms a handsome, symmetrical tree, which, on 

 account of its broad, lustrous foliage, is destined to be a favorite in cultivation. 

 Grows in low woods in northwestern Georgia and northern Alabama, and is com- 

 mon in the flat woods near Rome, Georgia (type locality). 



The original specimens {B1212 and B22J1) are preserved in the Biltmore 

 Herbarium. 



Crataegus algens n. sp. 



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

 trunk i-2 dm in diameter, clothed with dark gray or brownish-black 

 scaly bark, the ascending and spreading branches frequently 

 armed with stout chestnut-brown or gray spines : leaves obovate- 

 or oblong-cuneiform, sometimes broadly obovate or elliptic, the 

 blades 2-6 cm long, i.5~4 cm wide, either rounded or pointed at the 

 apex, wedge-shaped or more abruptly contracted at the base, the 

 borders serrate, at least above the middle ; they are glabrous at 

 maturity, bright green and lustrous on the upper surface, pale 

 beneath, and when young bear a few pale hairs along the midrib 

 on the upper surface, eventually firm or subcoriaceous in texture, 

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

 petioles 5-i.5 mm long, margined : flowers i2-i4 mm wide, opening 

 at the type station about the middle of May and when the leaves 

 are two-thirds or more grown ; they are borne in compound, gla- 

 brous, many-flowered corymbs, the lowest branches of which are 

 axillary: pedicels and hypanthium glabrous: sepals 4-5. 5 mm long, 

 entire or remotely serrate, spreading or reflexed after anthesis : 

 stamens about 10, the anthers yellow : fruit, which ripens in Sep 

 tember and October, subglobose or somewhat ovoid, 8-io mm 

 thick, dull red, or green and red at maturity: nutlets mostly 1-2, 

 7_8mm long, the ventral surface nearly plane : hypostyle 5 mm long.
