OF NORTH AMKiUCA. 11 



ing the Unaka or Iron Mts. of North Carolina, 

 their Western ridges are the Wasioto Mts. 

 vulgarly Cumberland Mts : the lofty Kiskanom 

 and Oquago Mts are the N. E. end of the Al- 

 leghanies nicknamed Catskill : the Mattawan 

 Mts. are those highlands broken through by the 

 Hudson, and East becoming the Taconic Mts. 

 The Saranac Mts. are those at the head of 

 the Hudson R. misnamed Peru Mts. The 

 Wapanunk are the White Mts. highest of New

NEW SYLVA, 



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 bilocular 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 

 and terminal jlowers This Genus has affini- 

 ties with Pyrus, Aroma, Mespilus, Crategus 

 fce, being of same family : it differs from all by 

 the unequal calix, 15 stamens, and dry fruit; 

 the seeds are nearest Aroma, yet I apprehend 

 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 

 n. of Crategus and Mespilus with serrate
