Description

This annual erect herb grows 150–260 mm (5.9–10.2 in) tall. It has a slender triangular furrowed stem. It is mostly hairless, but it is hairy below. The internodes are mostly longer than the lance-shaped oppositely arranged leaves. They are hairy with few or no teeth. The leaves mostly grow directly on the stem, but the lower leaves may have a short stalk. [1]

The terminal flowers are borne in broad racemes, each of which contains only a few flowers. The bracts are lance-shaped and re shorter than the leaves. The stalks holding them are slender with narrow glands. The calyx segments are linear and curved. They are covered in glands and dense, fine hairs. The petals are pale with a rounded lower lip and no margin at the tip. The palate (a rounded projection at the opening of the tube) is hairy and the spur is conical. [1]

Distribution and habitat

This species in endemic to the Northern Cape of South Africa. [2] It grows in Modderfonetin in Little Namaqualand. [1]

<i>Eremophila decipiens</i> Species of plant

Eremophila decipiens, commonly known as slender fuchsia bush or narrow-leaved fuchsia bush is a flowering plant in the figwort family, Scrophulariaceae and is endemic to an area extending from the south-west of Western Australia to southern parts of South Australia. It is low, sprawling shrub with lance-shaped leaves and red, orange or yellow flowers on a long, S-shaped stalk.

<i>Roridula gorgonias</i> Gorgons dewstick is an insect catching endemic shrub in the family Roridulaceae from South Africa

Roridula gorgonias is an evergreen, shyly branching, upright shrub of up to about 1 m (3 ft) high, from the family Roridulaceae. It has awl-shaped leaves with entire margins, crowded at the tip of the branches. These are set with tentacles that secrete a sticky, shiny resin from the thicker gland at their tips, that catch many airborne items. At the center of the shoots appear inflorescences between July to October that consist of up to twelve flowers in spikes, each on a short flower stalk, with a bract at its base. The 5-merous flower is about 2½ cm (1 in) in diameter and has pinkish purple or white petals. The plants do not digest the trapped insects, but the bug Pameridea roridulae sucks out their juices and the plant absorbs nutrients from the bug's droppings. It is therefore considered a protocarnivorous plant. It is called Gorgons dewstick, fly bush or fly catcher bush in English and vliebos, or vlieëbossie in Afrikaans.. R. gorgonias is an endemic species home to the southwest of the Western Cape province of South Africa.
