tion of stamens, I have ventured to transfer this species to the former genus, 

 where it naturally falls into Dr. Gray's section PMoganthea, and forms a link 

 of transition between the two genera. It may be here remarked that the 

 character of G'dia given by Bentham and Hooker (Genera, 2, p. 822), "semina 

 nunquam spirillifera", is evidently an oversight, since Dr. Gray, whose 

 elaboration of the genus is adopted in full, restricts it to the species with 

 opposite and palmately-cleft leaves.
