Crataegus rustica n. sp. 



A large shrub or small tree 2-6 m tall, sometimes with a trunk 

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

 bark, the spreading and ascending branches frequently armed with 

 stout, chestnut-brown or gray spines 2-5. 5 cm long: leaves ovate 

 or oval, the blades 2-5 cm long, i-5-5 cm wide, acute at the apex, 

 rounded, narrowed or on leading shoots truncate or cordate 

 at the base, the borders serrate and incisely lobed ; they are 

 glabrous when fully grown and when young are glabrous except 

 a small area at the base of the blade, which bears a few pale 

 hairs, bright green, thin to firm in texture, fading in autumn 

 with tones of yellow, orange and brown: petioles i-5-3 cm long, 

 glabrous : flowers i5-i8 mm wide, opening about the 10th of May 

 and when the leaves are two-thirds grown ; they are produced in 

 simple, 3-9-flowered corymbs which terminate short, leafy branch- 

 lets : pedicels and hypanthium glabrous : sepals 3-4 mm long, 

 mostly entire, reflexed after anthesis : stamens 20, the anthers 

 light yellow : fruit, which ripens late in September and in October, 

 subglobose, 7-1 i mm thick, obtusely angled and conspicuously 

 swollen below the middle, dull red at maturity, or red and green, 

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

 nearly plane : hypostyle about 4 mm long. 



Cratcegus rustica is common in old fields and woodlands near Biltmore, 

 North Carolina (type locality). 



The type specimens, which are deposited in the Biltmore Herbarium, repre- 

 sent both flowers and fruit from the same tree. 



Crataegus arcana n. sp. 



A shrub or small tree 2-6 m tall with a short trunk sometimes 

 2 dm i n diameter, clothed with dark gray or brownish-black scaly 

 bark, the spreading and ascending branches often armed with 

 stout chestnut-brown or gray spines 3-5 cm long : leaves ovate or 

 oval, the blades 2.5-6 cm long, 2-7 cm wide, acute or acuminate at 

 the apex, rounded or contracted, or on leading shoots truncate or 

 subcordate at the base, the borders sharply serrate and incised ; 

 they are glabrous when fully grown, and when young are some- 

 times a little pubescent along the base of the midvein, especially 

 on the lower surface, bright green, thin to firm in texture, fading
