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

 tlic nearly distinct stamens with no apical a])pendage. Tlie new species is a 

 just intermediate form connecting Staunfonia and HolbwUia. It is closely re- 

 lated to Holbadlia in tlie free stamens on one hand, Avhile ou the other it 

 resembl&s Stauntonia iu the acuminatc linoar se])als. 



Note : Flowers i^ale-green to crcam-vcJiow.
