Drosera kaieteurensis is a plant from the family of sundew plants ( Droseraceae ).
Description
Drosera kaieteurensis is a perennial, herbaceous plant that reaches the heights of growth from 1.3 to 6 inches. It makes indigenous rosettes with diameters of 6-8 mm on short stems. The wine-colored leaves lying on the ground, to circular spreading are 2-3 mm long and 2 to 2.5 mm wide, obtuse at the tip and occupied on the top edge with thread-like trichomes, center bald becoming inversely egg-shaped. The petioles are 4-6 mm long and measure around 0.5 millimeters in diameter, are silky, rarely growing weaker occupied with filiform trichomes.

System
On closer examination shows the relationship of Drosera Drosera felix kaieteurensis with or Drosera solaris. Especially seed dispersal is a common feature; All three types are Regenballisten. As these types also Drosera kaieteurensis is classified in the section Drosera subgenus same name.
