OREOPANAX (i.e., mountain Panax). Araliicea>. 

 Sour- ci^^hty species names have been referred to this 

 genus, but the number of species is probably not one- 

 half this number. In the trade, the species of Oreo- 

 panax are usually known as Aralias, but in the Aralia 

 tribe the petals are imbricate in the bud, whereas in 

 Oreopana.x they are valvate. The Oreopanaxes are tropi- 

 cal American trees and shrubs, with simple or coiiiponiiil 

 entire or toothed thick Ivs., and fls. in li.-iis,- li,.;i.U 

 which are arranged in racemes or panicbs ; ,-;il\\ with 

 minute or obsolete limb: petals 4-7, usually ... the st;i 

 mens of the same number and with ovate ur ubluiig 

 anthers: ovary 3-7-loculed. the styles rather long and 

 bearing a flat, not thick, stigma: fr. globose and berry- 

 liko. Few species of Oreopanax are known in cultiva- 

 tion. They are hothouse subjects, requiring the treat-
