Drosera uniflora is a carnivorous plant from the genus sundew ( Drosera ) and wasfirst describedby Carl Ludwig von Willdenow in 1809.
description
In Drosera uniflora is a very small rosette-forming sundew 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 blooms in January / February. The up to two flower stalks reach a height of only 1 to 3 centimeters and close - unusual for a sundew - with a terminal single flower. The inverted egg to wedge-shaped petals are white, 4 to 5 millimeters long and around 2.5 millimeters wide.
Distribution and habitat
The species is only found in the sub-Antarctic south of the fortieth parallel in Chile and on the Falkland Islands. It thrives in the undergrowth of forests with boggy soils and in bogs.
In Chile it is part of the plant communities Pilgerodendron-Astelia woodland , Valdivio-Magellanic Tepualia woodland , Magellanic Sphagnum bogs and Magellanic Carex-Tetroncium transition mires . In all of them it is associated with Astelia pumila , but often also with Sphagnum magellanicum , Pilgerodendron uvifera , Tepualia stipularis , Carex magellanica (and other Carex species), Tetroncium magellanicum , Myrteola nummularia and Oreobolus obtusangulus .
It also inhabits swampy soils on the Falkland Islands together with Astelia pumila , Oreobolus obtusangulus and peat moss ( Sphagnum ). Here it is also found associated with Pratia repens , Lilaeopsis macloviana , Montia fontana , Ranunculus trullifolius and Anagallis alternifolia .
