Hab. Mountains of Kauai, Sandwich Islands; "from a marsh, on 

 the table land." 



It is interesting to receive a Drosera from the Sandwich Islands, 

 and especially one of the boreal species. The specimens, in their 

 foliage, seeds, &c, are undistinguishable from Drosera longifolia 

 (applying that name, as I think we should, to the D. Anglica of 

 Hudson), a species which, with D. rotundifolia, is found quite around 

 the northern hemisphere from Oregon to Kamtschatka.

Steetz (1. c.) remarks that, having carefully examined many species 

 of Tetratheca, he has never found more than one ovule in each cell of 

 the ovary, and Payer (1. supr. cit), chiefly upon this authority, denies 

 the existence of a greater number, notwithstanding the phrase "Ova- 

 rium 2-loculare, loculis 1-3-ovulatis," in Mr. Brown's ordinal cha- 

 racter. To show, if need be, that this character is not "founded 

 upon an error," I may state that I find two (superposed) ovules in
