A very delicate plant and common in the Falkland Islands, though from its inconspicuous nature often over- 

 looked. It generally grows among grass by the margins of streams, forming pale green tufts, and is more allied to 

 the solitary -flowered Tasmanian species with axillary peduncles than to any European congener. Fuegian specimens 

 are larger in all their parts than those from the Falkland Islands.

I know no more of these two species than is conveyed in Poiret's descriptions ; Kunth, according to De Candolle, 

 considers the latter a Drgmaria.

Some of Mi'. Darwin's specimens have a very evident wing to their seeds, while in others it is not more con- 

 spicuous than in the Falkland Island plants, and never appears to afford a specific character. 



Like some other littoral plants, the Arenaria marina or media, (including C. rubra, in part at least), has a very
