maui: Forbes 861. M, East of Ukulele,

Car ex Nealae belongs in subgenus Eucarex 
Coss. & Germ., section Acutae Fries sub- 
section Vulgar es Aschens ( Kiikenthal 1909: 
305 ) . It has unquestioned Australian rela- 
tionships, being close to Car ex Gaudichaud- 
iana Kunth, which grows in bogs in the 
mountains of New South Wales and New 
Zealand. It differs from this species, how-
