Selma, Alabama (type locality), about the middle of April, borne 

 in 2-5- mostly 3-flowered corymbs : pedicels 5 mm -i v 5 cm long, 

 densely pubescent, and bearing one or more linear, glandular 

 and caducous bractlets : calyx obconic, densely pubescent, the 

 divisions about 5 mm long, glandular, reflexed after anthesis : sta- 

 mens normally 20, 3~5 mm long, the anthers yellow : styles 3-5, sur- 

 rounded at the base with pale hairs : fruit, which ripens early in 

 August, pyriform, 8-io mm wide, io-i3 mm high, orange-red, the 

 cavity 3~4 mm wide, surrounded by the persistent calyx segments : 

 nutlets 3-5, hard and bony, 6-7 mm long, 3-4 mm measured from

 the back without prominent grooves or ridges. 



Crataegus lassa is common in the sandy oak-barrens near Selma, Alabama. 

 Generally referred to C. flava in herbaria, the writer is, however, inclined to 

 associate and contrast it with C. michauxi Pers., 1. c, from which species it differs 

 mainly in the shape of the fruit and leaves. 



The type material is preserved in the Biltmore Herbarium. 



Crataegus frugiferens n. sp. 



A shrub 1-5 111 tall or occasionally arborescent, with a short, 

 slender trunk : bark of the trunk or larger branches dark ashy-

 tinged with reddish-brown, the growth of the season reddish- 

 brown marked by small pale lenticels : winter buds globular, the

 i-8 cm long including the petiole, i.5-6 cm broad, a little pubescent 

 at the time of unfolding, becoming glabrous or with a few hairs 

 along the winged glandular petioles and prominent veins, bright 

 green, fading in autumn with tones of yellow and brown, firm 

 in texture ; they are sharply and irregularly serrate and incisely 

 lobed, mostly acute at the apex, rounded at the base and abruptly 

 contracted into petioles 5 mm -2 cm long : flowers, which open in 

 the vicinity of Cullman, Alabama (type locality), the latter part 

 of April, borne in mostly simple 3-5-flowered very sparsely hairy
