The Telegraph plant ( Codoriocalyx motorius ), also called Indian telegraph plant, is a flowering plant in the legume family ( Fabaceae ). Special features of Codariocalyx motorius are occurring Nastien, fast movements as seen with the Venus Flytrap ( thigmonasty ) and mimosa ( Seismo - or thigmonasty ) can be found. Telegraph plant included in the vegetative parts of plants, small amounts of tryptamine alkaloids N, N- dimethyltryptamine and 5 -methoxy- dimethyltryptamine.

Description

In the Telegraph plant is an upright growing shrub with plant height 0.60 to 1.20 meters. The bark of young branches is hairy. The leaves are divided into petiole and leaf blade. The petiole is 1 to 2.5 cm long. The feathered leaf blade has one to three leaflets. The two lateral leaflets are 1-2 cm long and 3.5 to 4.5 mm wide. The terminal leaflet is 2.5 to 7.0 cm long and 6.5 mm to 13 mm wide. The upper leaf surface is smooth and the lower leaf surface is hairy silky. The elongated stipules are about 6.5 mm long.

The flowering period extends into Pakistan from August to September. The terminal or pendent, racemose inflorescences have large bracts. The flower stem is 3.5 to 6.5 mm long. The hermaphrodite flowers are zygomorphic and fünfzählig double perianth. The 2.5 mm long sepals are fused, with the calyx teeth are shorter than the calyx tube. The 7.5 to 8.5 mm long petals are pink.

Hairy legume is crescent-shaped with a length from 3 to 4.4 centimeters and a width from 5 to 6.5 centimeters.

The evening Endfiedern be lowered and thus depend almost vertically in the sleeping position down in the morning they will be re-erected and are nearly horizontal. This is done independently of external influences such as temperature and light intensity. This is a circadian rhythm. The lateral leaflets perform rotational motion, the frequency of which depends on the temperature. Temperature increases so does the frequency. Typically this frequency is one complete rotation for every three to five minutes. The function of these ultradian rhythm is still completely unknown. Both movements of the terminal leaflets and that of the lateral leaflets are realized by joints and turgor in the cells of these joints. The German name goes back to the fact that previously assumed that the plants are using the movements of the pinnae in a position to communicate with each other.

Dissemination

Codoriocalyx motorius has an originally widespread in the Indian subcontinent, Bhutan, Nepal, Myanmar, Cambodia, Thailand, Vietnam, China, Taiwan, Malaysia, Brunei, Indonesia, the Philippines, East Timor, the Little Sunda Islands, and Australia. In Mauritius and Martinique is Codariocalyx motorius. Whether it is unclear in the stocks in Jamaica and the Society Islands by natural occurrence or neophytes are there.
