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

501. XEROMALON Raf. ealix adherent 
globular, disk hairy, crown 5parted, 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 flowers — This Genus has affinh 
ties with P yrus, Aronia , Mespilus , C rategns 
&c, being of same family : it differs from all by 
the unequal ealix, 15 stamens, and dry fruit ;

it has been blended with C rategus, 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 
the sp. of Crategus and Mespilus with serrate
