Drosera paradoxa

Drosera paradoxa

Drosera paradoxa is a carnivorous plant from the family of sundew plants ( Droseraceae ). It occurs exclusively in the tropical north of Australia.

Description

In Drosera paradoxa are perennial, herbaceous plants with roots and fine-fiber terminated at age rosettes on woody stems that can be up to 30 inches high and 1.5 millimeters thick. The foliage below the active rosette lapsed and the plant to the flower stems, the lower side of blade, the flower stalks and sepals in different density fine white hairs.

The inner young leaves are erect, the outer are horizontally or hang down, the petioles are linear, the heyday of 20 to 35 millimeters long, 0.4 to 0.6 millimeters wide at the base, 0.2 to 0.4 millimeters wide in the middle and at the base of blade tapered to 0.1 to 0.15 millimeters wide, sparsely hairy. The nearly round leaf blades are 2-3 mm long, 2.5 to 3 millimeters wide, her top is open at the edge with a little longer, shorter muzzle middle tentacles, her bottom tightly with long, wooly, white hair.

The one to five rust-colored and hairy inflorescence axes arise from or below the rosette, 20 to 40 centimeters long and have a bunch of grapes from 50 to 70 or more flowers. The flower stems are 0.5 to 1.5 millimeters long and hang down to maturity. The sepals are elliptic, terete or vice versa lanceolate, 2 to 3.5 mm long and 0.8 to 1 millimeter wide. The petals are pink or white, with or without red Saftmal or cherry red, obovate and 4-12 mm long and 2.7 to 11 millimeters wide.

The stamens are 2 to 3 millimeters long. The ovary is obovate, 0.5 mm long, the heyday of 0.7 mm in diameter and with three carpels. The three stylus included scars 1.1 mm long, often branched at the top, each branch ends in a club-shaped scar.

The capsule fruit is obovate having a diameter 0.7 to 0.8 mm and contains 15 black, elliptical, and is provided with a net-like surface of seeds, which are 0.3 to 0.35 mm long and 0.2 mm in diameter.

Distribution and location

Drosera paradoxa is widespread in the tropical north of the Beverley Springs in Western Australia over the Kimberleys up to Arnhem Land and in the Kakadu National Park in the Northern Territory. There it grows on sandy soils in seasonally dry river beds and on, the reach considerable depths during the rainy season.

System

The closest related species is Drosera petiolaris, which, however, does not form a trunk and has considerably fewer flowers. The specific epithet refers to the paradoxical observations in the early days of exploration, during the different stages of the plants showed no clear picture of their life cycle. It was first described in 1997 by Allen Lowrie. The species belongs to the so-called " petiolaris complex", which is the section of the genus Lasiocephala.
