This beautiful species differs from all earlier known 

 in this, that two kinds of leaves appear on the branches. 

 These are certainly like each other in form, but the ventral 

 are much smaller than the lateral. To me it seems most 

 probable that this species belongs to a new genus. Unfor- 

 tunately there is only a sterile specimen at disposal.
