larger on leading shoots, pointed at the apex, rounded or con- 

 tracted at the base, or on vigorous shoots sometimes truncate, the 

 borders serrate and incised ; they are glabrous, or when young 

 display a few weak hairs on the upper surface of the midrib and 

 bases of the largest veins, firm to subcoriaceous in texture, green 

 or yellow-green, fading with tones of yellow, orange and brown : 

 petioles margined, 5-i5 mm long, glandular : flowers i5-i8 mm wide, 

 produced in simple, 5-8-flowered corymbs and expanding early in 

 April and when the leaves are about half grown : pedicels 

 and hypanthium glabrous : sepals 3-4 mm long, glandular-serrate, 

 reflexed after anthesis : stamens normally 20, the anthers small, 

 bright purple : fruit, which ripens and falls in October, globose, 

 about i cm in diameter, green or greenish-yellow at maturity, the 

 flesh firm : nutlets 3-5, about y mm long, the lateral surfaces plane 

 and the back ridged and grooved : hypostyle 4 mm long. 



CratcBgus attstrina is abundantly represented in the region about Green- 

 ville, Alabama (type locality), growing on wooded slopes in clay soil. 



The type specimens, representing flowers (B^/j/) and fruit (B^iji 2 ) from 

 the same tree, are preserved in the Biltmore Herbarium. 



Crataegus gilva n. sp. 



A shrub i-5 m tall with dark gray scaly bark and spreading 

 branches which are sometimes armed with chestnut-brown or 

 gray spines 2-4 cm long : leaves elliptic, ovate or ovate-lanceolate, 

 3~7 cm long exclusive of the petioles, i.5-5 cm wide, acute or acumi- 

 nate at the apex, narrowed or contracted at the base, the borders 

 serrate and incised ; they are glabrous when fully grown, but 

 when unfolding bear a few weak hairs on the upper side along 

 the midrib, thin to firm in texture, dark green, fading with tones 

 of yellow, orange, red and brown: petioles 1-2. 5 cm long, mar- 

 gined, often glandular: flowers i5-20 mm wide, expanding early in 

 May and when the leaves are almost fully grown ; they are dis- 

 posed in simple, glandular-bracteate, 3-7-flowered corymbs : pedi- 

 cels and hypanthium glabrous : sepals about 4 111111 long, glandular- 

 serrate, reflexed after anthesis : stamens 20, the anthers pale 

 purple : fruit, which ripens and falls in September and October, 

 subglobose or short-pyriform, 6-8 mm wide, at maturity yellow or 

 greenish-yellow, rarely with a flushed cheek, the flesh firm : nut-
