ing the Unala or Iron Mts. of North Carolina, 

 their Western ridges are the Waswto Mts. 

 vulgarly Cumberland Mts : the lofty Kiskanom

501. XEROMALON Raf. calix adherent 

 globular, disk hairy, crown Sparted, sepals une- 

 qual foliaceous persistent serrate. Petals 5 

 oboval concave subequal. Stamens 15 perigyne 

 subequal erect, subulate, base nearly monadel- 

 phous, anthers bilocuiar elliptical. Ovary ad- 

 herent, styles 5 filiform distinct, stigmas capi- 

 tate truncate. Fruit umbilicate crowned 

 a dry hard pomum, inside 51ocular 5seeded, 

 seeds cartilaginous oblong compressed nearly 

 winged around. Shrub with alternate leaves 

 ami terminal floiters — This Genus has affini- 

 ties with Fyrus, Aronia, Mesjnlus, Crategus

 it has been blended with Crategus, if already 

 described elsewhere ; but I could not find any 

 sp. to agree. Discovered 1818, the name 

 means dry apple. Only one species; but all 

 *u^ en. of Crategus and Mespilus with serrate
