Ceropegia fantastica is a species of the subfamily of the silk plant family (Asclepiadoideae).
features
Appearance, root, stem and leaf
Ceropegia fantastica is a perennial , herbaceous plant . A flattened, spherical root tuber is formed as a permanent organ . The winding stem axes are bare. The leaves are divided into a petiole and a leaf blade. The leaf blades are ovate to lanceolate and ciliate at the edges.
Inflorescence and flower
The very long inflorescence stem is hairy. The inflorescence contains four to seven flowers. The bare flower stalk is up to 1 cm long.
The hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The subtle sepals are usually longer than the corolla , with a length of 1.5 to 5 cm . The purple, yellow spotted corolla is 2 to 4 cm long. The five petals are fused in the lower part to form an externally bare corolla tube ( sympetalie ). The "Kronkessel" in the lower part of the corolla tube is obliquely oval-cylindrical and measures 6 to 11 × 4 to 6 mm. The "crown kettle" is bare on the inside and merges continuously into the actual crown tube. The corolla tube has a minimal cross-section of 3 mm and widens towards the mouth of the flower up to 6–7 mm. The corolla tube is whitish and has a few, small brown-red spots in the lower part, which become larger and denser towards the mouth of the flower. The upper half of the corolla tube is hairy on the inside. The egg-shaped petals are 5 to 10 mm long and 3 to 4 mm wide. The "laminae" of the tips are turned back along the longitudinal axis. The ends are fused together and form a spherical, cage-like structure. The edges of the "laminae" are ciliate and dark purple. The tips are greenish in the lower part, a white area follows above and a green area above again. The bald adjoining crown is sessile and fused at the base. The tips of the interstaminal , outer secondary crown are triangular-ovoid, incised in the middle and drawn out into narrow triangular appendages. The tips of the staminal , inner secondary crown are linear and stand upright; the tips are again slightly bent back. According to Ansari (1984) and Jagtap & Singh (1999) , the flowering time is in August (from July).
Fruit and seeds
The paired follicles are very slim with a length of about 9 cm and a diameter of only about 3 mm. The elongated seeds are 8 mm long and 3 mm wide. According to Ansari (1984) and Jagtap & Singh (1999) , the fruits appear in September.
Similar species
Within the genus of candlestick flowers, the sepals are only longer than the corolla in Ceropegia fantastica .
Occurrence and endangerment
Ceropegia fantastica is common in the Indian states of Goa ( South Goa District), Karnataka ( North Kanara District , Sindhudurg District ) and Maharashtra . The type locality in Karnataka is at an altitude of 150 meters. It thrives there on lateritic soils in light, evergreen forests.
Ceropegia fantastica is threatened with extinction in its natural habitat. There are therefore already programs running to artificially reproduce the species and distribute it to suitable locations.
Taxonomy and Phylogeny
The first description of Ceropegia fantastica was in 1959 by Leonard John Sedgwick . The type material comes from Sulgeri (not localized) in the North Kanara district in the Indian state of Karnataka.
According to the phylogenetic analysis by Surveswaran et al. In 2009 Ceropegia fantastica is the sister species of Ceropegia evansii .
