@NaN: hrm..... at what temps are you growing/did you grow D. roraimae in? the fact that it dies on you puzzles me, since it was the most plentiful Drosera represented during my trip. from what i could tell, it didnt have that many demands as it would grow in mud/peat, as well in moss and lithophytically, and sometimes even epiphytically! maybe solid highland conditions are necessary? high humidity? could you provide more information?
sorry for going off tangent!
