 Crood Hope; from Japan to Victoria, also throughout Polynesia ; but

Careoc Linn. 



Carex arenicola F. Sen. 



Hab. in monte Morrison, leg. G. Nakahaea, 1905. 



The present specimen exactly accords with those so named 

 in the Herbarium at Kew and also with those at Tokyo. It 

 would be very remarkable fact if this Carex should really exist in 

 the mountains of Formosa. It may be doubted, however, if the speci- 

 men might not be one of the collections from Sachalin island, for the 

 collector was sent to Formosa immediately after he had finished 

 his work in Sachalin ; and it may be well conjectured that the 

 present specimen, having escaped from the northern collections, 

 was sent to me from the same collector then in Formosa.
