capsules abruptly contracted at the base, about i cm long, 8~9 mm 

 wide, persistent long after the falling of the leaves. 



Philadelfhus gloriosus grows on the rocky banks of the Coosa river near 

 Rome, Georgia (type locality). Undoubtedly related to P. grandiflorusVJ illd. , 186 

 but obviously differing from this species in the very abrupt point of attachment 

 between the pedicel and capsule. 



The type material is preserved in the Biltmore Herbarium. 



Philadelphia floridus n. sp. 



A deciduous shrub 2-3™ tall with branching stems, the bark 

 of the last season's shoots dark brown, exfoliating : leaves oval 

 or elliptic, the blades 4~io cm long, 2~5 cm broad, acute at the apex, 

 either rounded or narrowed at the base, the borders remotely 

 toothed ; they are glabrate above, sparsely pubescent on the lower 

 surface, prominently 3-nerved, or occasionally 5-nerved, thin in 

 texture, bright green above, pale beneath, falling in early autumn: 

 petioles 3-7""" long: flowers occasionally solitary but mostly 3-5, 

 3-4 ram wide, expanding early in May : pedicels and hypanthium 

 appressed pubescent : sepals acuminate, the exterior surface ap- 

 pressed pubescent : stigmas not united. 



Philadelfihtis floridus was originally collected on the rocky slopes and banks 

 of the Coosa river near Rome, Georgia. Differs from all of the species of the 

 South Atlantic region with few or solitary flowers by the pubescence of the 

 pedicels and hypanthium. 



The type material is preserved in the Biltmore Herbarium. 



Philadelphus intectus n. sp. 



A deciduous shrub 2-3 m tall with branching stems, the bark 

 of the shoots gray or ochre-color, not exfoliating : leaves ovate, 

 oval or elliptic, the blades 3-i2 cm long, i-5 cm wide, acute or 

 acuminate at the apex, either rounded or narrowed at the base, 

 the borders entire or remotely dentate ; they are glabrous or gla- 

 brate on both surfaces, prominently 3 - nerved, or sometimes 

 5-nerved, thin in texture, bright green above, pale green beneath, 

 falling in early autumn : petioles 3-7^1x1 } ng : flowers racemose, 

 mostly numerous, the lower pair axillary, 3~4 cm wide, expanding
