features

Appearance, root, stem and leaf

Ceropegia ensifolia is a perennial , herbaceous plant . A spherical root tuber is formed as a permanent organ . The delicate, almost bare stems are twisting and branch out. The oppositely arranged leaves are short stalked or almost sessile with a length of up to 8.5 mm. The almost bare leaf blades are ruler with a length of 10 to 18 cm and a width of 0.85 to 0.4 cm.

Inflorescence and flower

The flowering time is in August and September. The hairy peduncle is often relatively long with a length of 2.5 to 12.7 cm. The zymous inflorescence contains many flowers. The hairy flower stalk is very short.

The hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The five sepals are 4 mm long. The corolla is up to 4 cm long. In the lower part are the five petals to a lean, approximately 20 mm long corolla tube ( Sympetalie ) grown. The corolla-tube is white or whitish green, and at the base it is inflated to a "crown kettle". With a length of 1 to 2 cm, the linear, upright petal lobes are fused at the outer ends and form an egg-shaped, cage-like structure. The two " leaflets " of the tips are slightly bent outwards along the longitudinal axis. The sessile secondary crown is fused at the base. The tip of the interstaminalen outer Nebenkrone are triangular and hairy, or hardly formed. The tips of the staminal , inner secondary crown are linear-spatulate and stand upright and straight.

Fruit and seed

The paired follicles are 15 to 18 cm long. No information is available on the seeds.

Occurrence

Ceropegia ensifolia occurs in the southern Indian states of Kerala and Tamil Nadu . It grows there at altitudes of 1000 to 1500 meters.

Taxonomy

The first description of Ceropegia ensifolia was in 1864 by Richard Henry Beddome in the 1st volume of the 3rd series of the Madras Journal of Literature and Science and was shown only a little later in his Icones . A more recent synonym of Ceropegia ensifolia Bedd. is Ceropegia albiflora Hook. f. published in 1883 by Joseph Dalton Hooker . Herbert Huber devalued the taxon in 1957 as a subspecies of Ceropegia ciliata ; viz. Ceropegia ciliata subsp. ensifolia (Bedd.) H. Huber. Ansari (1984) re- classified the taxon as an independent species.
