Description

Huernia quinta is a plant species from the subfamily of the milkweed family (Asclepiadoideae). Huernia quinta makes stem succulent, grey-green, erect or ascending, often slightly twisted, relatively thick shoots that grow to about 7 cm high and about 2 cm thick on average. In cross-section, they have 4 to 5 ribs and are densely covered with dirty-cream-colored warts, up to about 4 mm long. The leaf rudiments are hard, whitish and persistent. The flowers point upwards with the flower opening. Occasionally two or three flowers are open at the same time. Sometimes there are also two flowers on one flower stalk; this is usually shorter than 1 cm. The sepals measure 5 × 1.5 mm. The corolla has a diameter of min. 2.0 to max. 3.5 cm, mostly 2.5 to 3 cm. It is cauldron-shaped with a widened rim and outstretched, partially slightly bent back tips. Internally the flower is white or creamy white, the flower-tube is stippled with red dots, the slightly pentagonal opening of the tube shows a few concentric, partially broken red lines. The diameter of the tube is 0.7 to 1 cm. The tips are triangular and slightly pointed. They are densely papillae at the top. The papillae are flattened conical or hemispherical, occasionally covered with a bristle up to 1 mm long. The side crown is cream to light brown, occasionally with brown spots. It measures 3 to 4 mm in diameter and is 4 to 5 mm high. The interstaminale coronary lobes are quite short, crenate to serrate. The staminal coronary lobes are about 1 mm wide with a blunt end. They meet above the stylus head. The surface is covered with very fine, blunt warts. The stylus head is conical and has a transverse groove basally. The pollinia are brownish with a slightly darker germ zone.
