The Indian lotus flower ( Nelumbo nucifera Gaertn. , Syn . : Nelumbium speciosum Willd. , Nymphaea nelumbo L. ) is a species of lotus flower ( Nelumbo ) in the lotus family (Nelumbonaceae).

features

The Indian lotus flower is a runners-forming, perennial herbaceous water plant . The stalked leaves are peltat. The leaf stalks are 2 m or more long. The round leaf blade is 60 cm or more in diameter.

The hermaphroditic flowers are radial symmetry . The many 1 to 13 cm long bracts are pink, tinted pink or white (in some varieties also yellow) and obsolete. The anthers are 1 to 2 cm long. There are many free carpels . For pollination , the flower uses a temporal gender separation, i. H. the female sexual organs (carpels) mature before the male ones (anthers). In addition, the bowl-shaped inflorescences warm up. Since nectar is not offered, it is believed that in addition to the scent, bees, flies and some bugs are attracted by the heat.

The flower axis tapers evenly towards the base at the time of fruiting and is often slightly rounded above the flower stalk. The egg-shaped fruit has a size of 10 to 20 × 7 to 13 mm. The nut fruits are egg-shaped or ellipsoid, measure 10 to 20 × 7 to 13 mm and are more than 1.5 times as long as they are wide and sunk into the flower axis.

The number of chromosomes is 2n = 16, less often 24.

Occurrence

The Indian lotus flower originally came from India to Japan , south to Korea and the north of Southeast Asia , but also isolated in the area of ​​the Aral Sea and Caspian Sea . The plant was spread by humans south to northeast Australia and North and South America .

The tubers are dried and made into flour or cooked and served with vinegar and soy sauce as a side dish. Young leaves and petioles are cooked as vegetables. The seeds are eaten fresh as lily buds , candied or roasted as a snack or cooked as a side dish. So far only in Myanmar is lotus silk made from the plant fibers.
