coated with white tomentum on both surfaces at the time of un 

 folding, and when half-grown are bright green, tomentose 01 

 pubescent along the lower portion of the midrib and principal 

 veins and in their axils on both surfaces, becoming in age deep 

 .green, rather inconspicuously pubescent on both sides, firm to 

 subcoriaceous in texture, fading in autumn with tones of yellow, 

 orange and brown : petioles 5 mm -2 cm long, tomentose or pubes- 

 cent, margined, glandular : flowers about 15mm wide, opening 

 early in April and when the leaves are barely half grown ; they 

 are produced in simple, 3-5-flowered corymbs which terminate 

 short, leafy branchlets or fascicles of leaves : pedicels and hy- 

 panthium tomentose : sepals 4-5 mm long, serrate, glandular, re- 

 flexed after anthesis : stamens 20, the anthers light yellow : fruit 

 globose or subglobose, 7-9™™ in diameter, red at maturity : nut- 

 lets 3-5, about 6 mm long, the lateral surfaces nearly plane : hypo- 

 style about two-thirds as long as the ventral angle. 



Cratcegus cirrata, on account of the wavy or crisped leaves, presents a 

 peculiar and striking appearance. The original specimens were gathered on the 

 gravelly hills at Girard, Alabama. 



The type material, representing flowers (B4122) and fruit (B4/22 2 ) from the 

 same individual, is preserved in the Biltmore Herbarium. 



Crataegus arguta n. sp. 



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

 trunk i.5 dm in diameter covered with dark, rough bark, the 

 drooping branches, which are frequently armed with short, stout 

 spines, forming an irregular, spreading crown : leaves cuneate 

 or obovate-cuneiform, the blades 1.5-3°™ long, 8 mm -2.5 cm wide, 

 rounded or abruptly sharp-pointed at the apex, wedge-shaped 

 or more abruptly contracted at the base, the borders dentate, 

 glandular or shallowly lobed, especially above the middle ; they 

 are pubescent, at least on the lower surface at maturity, and at 

 the time of unfolding are densely covered with tomentum on 

 both sides, dull green when young, becoming bright green with 

 age, firm to subcoriaceous in texture, fading in autumn with 

 tones of yellow, orange and brown : petioles 5 mm --2 cm long, winged, 

 glandular, tomentose or pubescent : flowers about I5 mm wide, 

 opening early in April and when the leaves are one-half or two-
