The genus Tetraplasandra derives its name from the Greek rerpamAasws 
(tetraplasios), fourfold, and a8pa (andra), stamens, having four times as many 
stamens as petals. It consists of possibly 12 species. two of which are not found 
in the Hawaiian Islands; 7. paucidens Mig. oceurs in New Guinea, while 7. 
Koerdersii Harms is found in Celebes. Of Hawaiian species, only two were de- 
scribed originally, 7. hawaiiensis A. Gray and T. Waimeae Wawra. All the 
species of Triplasandra (established by Seeman) have been merged into Tetra- 
plasandra by H. Harms. The writer has since added two new species: 7. 
Lanaiensis and T. Waialealae.
