Drosera peltata

Drosera peltata subsp. auriculata, Tasmania

Drosera peltata is a carnivorous plant in the genus Sundew ( Drosera ). It was first described in 1797 and is the most widely used tuberous Sonnentauart.

Description

Drosera peltata is a perennial, herbaceous plant with a height of up to 25 centimeters. Since the habitat of the species usually a drought is exposed to excessive heat in the summer, she undresses for this time in about six centimeters deep in a red, ball-shaped bulb having a diameter of up to 8 millimeters back. After their summer rest, it forms first from a rosette lying flat on the ground before it grows two to three months from its center to the height at the upper end it branches out occasionally. The root system is poorly developed.

The species has two different leaf shapes. The rosette leaves are up to 16 millimeters long, the thin petiole almost twelve millimeters long and one millimeter wide, transversely elliptical, slightly concave leaf blade four millimeters long and eight millimeters wide. The along the stem axis to up to ten millimeters long petioles standing, shield-shaped and strongly concave leaf blades have a diameter of three to four millimeters.

Flowers

Starting in the spring blooms the way that the inflorescence is a wrap, the hairless flower stalks are eight to ten millimeters long. The occupied with small glandular hairs sepals are up to three millimeters, which is inversely egg-shaped, slightly toothed, white petals up to four millimeters long.

Dissemination

The species is the most widespread of all Knollendrosera, she finds herself in China, Japan, on the back the Indian peninsula in western India, Sri Lanka, Indonesia, the Philippines, Australia, and Tasmania.

The wide spread distribution of Drosera peltata is also related to their relatively high tolerance to different habitats together, so the plant can also do without the indispensable for most Knollendrosera summer rest and settle permanently humid locations.

System

In addition to the nominate many more varieties have been described, recognized the subspecies

• Drosera peltata subsp. auriculata

With high probability to synonymisieren is the Drosera insolita probably erroneously described from the Congo.
