378 ART. I.—B. HAYATA:! 
Distris. Kwangtung, Hongkong. From Sweden to the Cape of 
Good Hope; from Japan to Victoria, also throughout Polynesia ; but 
absent in India and West Malaya (after Hemstey). 
Carex LINN. 
Carex arenicola I". Scu. 
Has. in monte Morrison, leg. G. Nakanara, 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.
