Resembles to some extent S. ckinensis DC.; but greatly differs from it by 







tlie nearly distinct stamens with no apical appendage. The new species is a 

 just intermediate form connecting Stauntonia and HolbodUa. It is closely re- 

 lated to Holhcdlia in the free stamens on one hand, while on the other it 

 resembles Stauntonia in the acuminate linear sepals. 

 Note : Flowers pale-green to creain-yello\v.
