Ceropegia haygarthii is a plant of the genus ceropegia ( ceropegia ) of the subfamily asclepiadoideae (Asclepiadoideae). The specific epithet honors the engineer and plant collector Walter Jacques Haygarth (1862–1950).
features
Ceropegia haygarthii has persistent and twisting stems that can be up to 3 m long. They are dark green, usually smooth or slightly covered with small warts and measure 3 to 4 mm in diameter. The roots are fibrous or fleshy. The stems and leaves are succulent. The perennial leaves measure 3 to 7 × 2 to 5 cm. The leaf stalks are 5 to 15 mm long. The elongated-oval to narrow-oval leaf blade is pointed, the leaf margins are finely serrate.
The inflorescence is stalked and one to few flowers . The flower stalk measures around 4 to 15 mm, the flower itself around 3 to 5 cm. The sepals are very slender and pointed, and measure up to 8 mm (depending on the size of the flower). The basic color varies from whitish to yellowish, the flower is more or less spotted green-brown to red-brown depending on the variety. The crown cup is round and thick and measures up to about 5 mm in diameter. It is slightly constricted near the base, the area below the constriction is white, the main part of the crown cup is greenish with red spots. The corolla tube is sharply narrowed (2 to 3 mm) and kinked (over 90 °) compared to the crown basin. It expands like a funnel to about 14 to 20 mm. The five corolla lobes are fused in the center and widened like leaves downwards and towards the center. Both sides of these “leaves” are green or, in the case of other shapes, also brownish-red, the narrow upper sides of the “leaves” are whitish and covered with white hairs. In the center, the distal parts are drawn out into a stem, at the tip of which sits a spherical or elongated brown-red head ("capitulum"). It consists of five narrow, outwardly curved segments that virtually form a small window blossom. In other forms, the head is also light brown or whitish. The head is covered with long white hair.
The slender follicles have a diameter of 2 to 3 mm and a length of 8 to 12 cm.
Occurrence
This species is native to Angola , Mozambique and South Africa. In addition to Ceropegia linearis ssp. woodii and the climbing candlestick ( Ceropegia sandersonii ) are the most common Ceropegia species in culture.
Systematics
Ceropegia haygarthii is also only viewed by some authors as a variety of the Ceropegia distincta native to Zanzibar (as Ceropegia distincta var. Haygarthii ). It is closely related to Ceropegia somalensis . Ceropegia angusta Hutchinsson is a synonym .
