Drosera hilaris is a carnivorous plant native to South Africafrom the sundew family(Droseraceae).
description
Drosera hilaris are vigorous and unbranched, herbaceous plants . They grow upright, partly from older, prostrate trunks that are densely covered with the old, withered, drooping leaves. The roots are poorly developed.
The leaves are arranged like rosettes to roof tiles, the petiole is hairy and merges smoothly into the blade, stipules are missing or are reduced to a few fused bristles below, which are obsolete and hidden in the dense, rust-colored felt. The blade is narrow, inverted-lanceolate, up to 7 centimeters long and 9 millimeters wide, it has exclusively club-shaped tentacles and the underside is very hairy.
The inflorescence axis arises from the leaf axils, is upright, leafless and up to 25 centimeters long, at its end it bears six to twelve large flowers on short flower stalks . The sepals are fused, the individual lobes are up to 6 millimeters long and narrowly egg-shaped. The petals are broadly inverted-egg-shaped, simple or notched, magenta to reddish-purple and have a length of up to 1.5 centimeters.
The short stamens are flattened, the stamens widened upwards. The styles are divided, long and spread out, the scars are either completely or briefly split and slightly swollen. The capsule fruits are egg-shaped, the seeds thread-shaped, winged at the tip and 0.5 millimeters long.
The number of chromosomes is 2n = 40.
distribution
The species is only found on the Cape Peninsula of South Africa, the easternmost point of distribution is Hermanus , where it grows on sheltered slopes. Drosera hilaris is rare.
Systematics
Drosera hilaris was first described in 1826 by Ludolf Karl Adelbert von Chamisso and Diederich Franz Leonhard von Schlechtendal . Like the very similar Drosera ericgreenii , Drosera hilaris is placed in the Drosera section of the subgenus of the same name.
