features
Vegetative characteristics
Ceropegia beddomei is a perennial , herbaceous plant . The upright, growing shoot axes are sparsely hairy. The leaves are divided into a petiole and a leaf blade. The leaf blade is linear to narrowly lanceolate and tapers at the outer end.
Inflorescence and flower
The stiff inflorescence stem is up to 3.5 cm long and hairy. The zymous inflorescence contains few flowers. The hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The five sepals are thread-shaped. The corolla is comparatively large with up to 7.8 cm. In the lower part, the five petals have grown together to form a bare, deep purple corolla tube ( sympetalie ). The corolla tube, which is up to 3.5 cm long, is inflated to a corolla in the lower area and widens in the shape of a funnel towards the hairy flower mouth. The inside of the corolla tube is bare except for the hair at the mouth of the funnel. The elongated triangular petal lobes are 4.3 cm long and fused with the ends; they thus form a cage-like structure. They are hairy on the inside along the longitudinal axis and on the edges. The secondary crown is fused in a flat, bowl-shaped manner. The tips of the interstaminal , outer secondary crown are short, incised in the middle and formed into two triangular hairy appendages. The tips of the staminal, inner secondary crown are tongue-shaped and stand upright; the ends diverge slightly outwards. As heyday give Ansari (1984) and Jagtap et al. (1999) the month of November.
Fruit and seeds
So far there is no information on fruits and seeds.
Occurrence and endangerment
Ceropegia beddomei has so far only been found at several locations in the southern Indian state of Kerala ( Thiruvananthapuram , formerly Trivandrum , Ponmudi , Idukki , Travancore , Peermade ). It thrives there at altitudes of 750 to 1000 meters.
Ceropegia beddomei is considered "Endangered" = "highly endangered".
Taxonomy
The first description of Ceropegia beddomei was in 1885 by Joseph Dalton Hooker in the 4th volume of his Flora of British India . Synonyms are not known.
