Ceropegia fimbriifera is a species of the subfamily of the silk plants (Asclepiadoideae).
features
Appearance, root, stem and leaf
Ceropegia fimbriifera is a perennial , herbaceous plant. A flattened, spherical root tuber is formed as a permanent organ . The tuber is spherical. The independently upright, hairy stems are 20 to 30 centimeters high. The opposite leaves are sessile. The leaf blades are linear, hairy on top, and hairy on the underside along the leaf veins .
Inflorescence and flower
The flowering period is from July to August. The inflorescences arise from the leaf axils. The 1 to 2 cm long inflorescence stem is almost bare. The inflorescence contains only one to four flowers that open successively. The flowers stand over a few awl bracts . The flower stalks are 1 to 2 cm long.
The hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The five sepals are sub-like and pointed. The corolla is up to 4.5 cm long. The five petals are fused in the lower part to form an externally bare, straight corolla tube ( sympetalie ). The corolla tube is greenish with purple longitudinal stripes and purple inside. In the basal part of the "Kronkessel" is only slightly inflated. With a length of 25 mm, the petal lobes are linear-spatula-shaped with a triangular base; they incline at the outer end and form an elongated-elliptical, cage-like structure. Occasionally the petal tips are twisted a little. The two “ leaflets ” of the tips are bent outwards below the middle. The essentially bald tips are light green-purple on the inside and the edges purple. Only at the base are tufts of purple-colored, club-shaped glandular hairs that are 3 to 4 mm long. The short-stalked secondary crown is fused cup-shaped at the base. The ciliate tips of the interstaminal , outer secondary crown are laterally fused with the staminal secondary crown and deeply incised in the middle, forming two triangular appendages that are spread sideways. The tips of the secondary staminal crown are linear-spatulate, upright and inclined towards the outer end.
Fruit and seed
The fruits appear in August and September. The paired follicles are slender spindle-shaped with a length of 7 to 10 cm. No information is available on the seeds.
Similar species
According to U. Meve, Ceropegia fimbriifera is said to be closely related to Ceropegia attenuata and Ceropegia noorjahaniae . Like these two species, Ceropegia fimbriifera has an upright habit, a tuber and linear leaves. The phylogenetic analysis with the help of molecular genetic data does not confirm the relationship between Ceropegia attenuata and Ceropegia noorjahaniae . According to Surveswaran et al. (2009) Ceropegia attenuata and Ceropegia noorjahaniae are not closely related; No molecular genetic data are yet available for Ceropegia fimbriifera .
Occurrence and endangerment
Ceropegia fimbriifera occurs in the southern Indian states of Karnataka , Kerala and Tamilnadu at altitudes of 900 to 1200 meters. It grows there on stony slopes in an open landscape.
Ceropegia fimbriifera is very rare in the range and is therefore considered endangered.
Taxonomy
The first description of Ceropegia fimbriifera was in 1861 by Richard Henry Beddome . The type material comes from the A'naimalai Mountains ( Coimbatore District , Tamil Nadu , India). In 1874, Ceropegia fimbriifera was first depicted in Beddome's Icones Plantarum Indiae Orientalis .
