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

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

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

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

 resembles Stauntonia in the acuminate linear sepals. 



Note : Flowers pale-green to cream-yellow.
