New Hawaiian Plants.— IV. 



Chari.es N. Forbes. 



I^ysittiachia koolauensis, nom. nov. 



L. lojiffisepala Forbes, in Occasional Papers, B. P. B. M., IV, 222 (1909) not 

 Forrest, in Notes Roj^ Bot. Gard. Edin. XIX, 237 (190S). 



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 longisepala 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 Oahti, 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.
