description
The goat's foot morning glory is a perennial herbaceous or slightly succulent plant and spreads by creeping or climbing. The plants are hairless, the stems are thick and can be up to 20 m long. The 6 to 10 cm long foliage leaves have long petioles , the outline of the leaf blade is almost circular, the tip is broadly rounded, bulged and slightly bilobed, the base is rounded or somewhat heart-shaped. At the base of the midrib, a gland can be made out on both sides of the underside. The leaves point upright to protect against the heat in the habitats. The roots are long and surrounded by thick brown bark .
The inflorescences consist of one to several flowers , the strong, usually forked inflorescence stalks are about as long as the leaf stalks. The flower stalks are 2 to 5 cm long and slender. The approximately 1 cm long sepals are oval or almost circular and rounded or blunt at the tip. The crown reaches a length of 4 to 5 cm and a diameter of 5 to 8 cm and is pink to purple in color, the sap mark is darker.
The fruits are egg-shaped, spherical capsules that are about 1.5 cm long and open through four flaps. They contain four seeds in two seed chambers , which are densely covered in dark brown hair.
The number of chromosomes is 2n = 30.
distribution
The goat's foot morning glory is widespread on tropical beaches around the world, where it is one of the pioneering plants and sometimes appears as a characteristic of certain plant communities, for example in the "pes caprae formation" named after it, where it is mainly associated with Canavalia maritima 'habitus similar to a legume species' occurs. The strong roots bind the sand and prevent the soil from being washed away. The species also colonizes non-marine locations inland or on freshwater beaches.
etymology
The German name Ziegenfuß-Morning glory is derived from the shape of the leaves, which are reminiscent of a goat's foot. The meaning of the epithet is also derived from it.
