Drosera erythrogyne

Drosera erythrogyne is a carnivorous plant in the genus Sundew ( Drosera ). The species is first described in 1992 with a reported length of over three meters, the largest Sonnentauart at all.

Features

Drosera erythrogyne is a perennial, herbaceous, climbing plant. The shoot axis reaches lengths of up to 200 centimeters, in exceptional cases even up to 310 centimeters, making it the highest Sonnentauart the world.

The leaves are in bunches of three along the stem axis. The central sheet here has a highly elongated petiole 3-4 cm long, the leaf blade is 2.5 mm long, 3 mm wide, crescent-shaped. The two lateral leaves are stalked with much shorter petioles of about 1 centimeter, the leaf blade is broadly kidney-shaped. Both leaf shapes are shield-shaped and occupies at the leaf margins with stalked glands.

The inflorescence is a panicle from 30 to 60 (rarely to 400) white flowers. The individual flowers are on 1 -inch-long flower stems. The sepals are elliptical, 4 mm long, 2 mm wide, finely occupied on the edge with stalked glands. The petals are inversely egg-shaped, 1 cm long, 6 mm wide and notched slightly at the extreme edge. The five stamens are 6.5 millimeters long, the stamens are white, the pale yellow anthers, the pollen is whitish - translucent. The ovary is inversely - ovate, 1.5 mm long, as wide and red. The three pens are white, red at the base, 4 mm long and many segmented. Bloom time is from September to March.

The tuber is white, round, has a diameter of 1.5 centimeters and forms up to 15 centimeters long streamers. Like all so-called " Knollendrosera " it contracts during periods of high temperatures and relative drought in these tuber back and survived underground.

Distribution and habitat

The species is endemic to the area between Augusta and Albany in the southwest of Australia. They settled there, wet, sandy peat soils or pure peat. In the same areas there is also the very similar Drosera pallida, but which preferred locations that are significantly drier during the summer rest. In contrast, there is Drosera erythrogyne to take ate locations.
