Drosera hirticalyx, Tropical sundew in habitat on tepui summit (tepui I), Canaima National Park, Bolivar Venezuela
Elevation 2500m. The plants in these two images represent the only occurrence of this species on tepui I.
Note the stacking of generations of leaves resulting in tall columns of plants. this phenomenon is only observed in tropical Drosera spp. which do not experience dormancy as part of their ecology. Temperate species and some tropical species which enter a dormancy do not elongate over multiple years of growth.
