New Hawaiian Plants.—IV. 
CHARLES N. FORBES. 
Lysimachia koolauensis, nom. nov. 
L. longisepala Forbes, in Occasional Papers, B. P. B. M., IV, 222 (1909) not 
Forrest, in Notes Roy. Bot. Gard. Edin. XIX, 237 (1908). 
On consulting the latest supplement to the Index Kewensis, 
which was not previously available, I find that the above change 
of name is necessary, as the name /ozg7zsepala was preoccupied for 
a Chinese plant by Forrest. As more extensive field collecting 
has not extended the range of this plant beyond the Koolau range 
of mountains on Oahu, it seems appropriate that the plant should 
bear this name. A point not mentioned in the original descrip- 
tion is that it often has a creeping rhizome.
