Description

In Drosera uniflora is a very small rosette- forming sundew with flat, down to earth rosette. The leaf stalks are 8 to 12 millimeters, the spatula - to -circular catch leaves about 3 millimeters long and 2.5 millimeters wide.

The plant flowers in January / February. Up to two flower stems reach a height of only 1 to 3 inches and close - unusual for a sundew - terminated by a single flower. The reversed oval to wedge-shaped petals ( petals ) are white, 4-5 mm long and 2.5 mm wide.

Distribution and habitat

The species is only subantarktisch south of the fortieth degree of latitude to find in Chile and the Falkland Islands. It grows in the undergrowth of forests with marshy soils and peatlands.

In Chile, it is part of the plant communities Pilgerodendron - Astelia woodland, Valdivio - Magellanic Tepualia woodland, sphagnum bogs and Magellanic Magellanic Carex Tetroncium transition mires. In all it is associated with Astelia pumila, but also often with Sphagnum magellanicum, Pilgerodendron uvifera, Tepualia stipularis, Carex magellanica ( and other Carex species), Tetroncium magellanicum, Myrteola nummularia and Oreobolus obtusangulus.

Also in the Falkland Islands they settled swampy soils together with Astelia pumila, Oreobolus obtusangulus and peat moss ( Sphagnum). Here it is found associated with Pratia repens, Lilaeopsis macloviana, Montia fontana, Ranunculus trullifolius Anagallis alternifolia and beyond.
