h'olhiiulia Idiiccolala is an exceedingly variable species; lliUebrand's varie- 

 ties enumerated in his Flora are too vague to be upheld; they have all save var. 

 t and ^ been cla.ssed with the species proper. The largest leaved specimens come 

 from Palolo Valley. The species is not unconnnon at the lower levels on Oahu, 

 where it occurs in nearly all the valleys. It is at once distinguished by the 

 glabnuis calyx and cdrnija and hirsute staminal cohunn and anthers.
