Planta gracilis, Callitrichem autumnalem referens. Caules 3-5 unc. longi, ramosi, ramis fere filiformibus. Folia patentia, læte sed pallide viridia, ½ - ¾ unc. longa, 1½- 2 lin. lata, nervis duobus marginalibus instructa. Pedunculi validi, florem solitarium pro planta majusculum gerentes.
A very delicate plant and common in the Falkland Islands, though from its inconspicuous nature often overlooked. 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 Drymaria.

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