The aquatic plant family Nelumbonaceae comprises two species and one of them is Nelumbo nucifera (Lotus). Currently, the recognized name of this species is Linnaean binomial Nelumbo nucifera (Lotus), which is classified under its several earlier names, including Nymphaea nelumbo and Nelumbium speciosum. This is a perennially growing aquatic plant. When the conditions are favourable, the seeds of this plant continue to be viable for numerous years. It is amazing to note that the oldest seeds of lotus that germinated successfully are those that were 1,300 years old and picked up from the dry bed of a lake located in the north-eastern part of China.

There are several instances where the lotus has wrongly been referred to as the water lily (belonging to plant family Nymphaea), a completely dissimilar plant that is evident from the flower’s center that does not have the structure that later on develops into a characteristic rounded seed pod in the case of Nelumbo nucifera (water lotus).

The roots of the lotus plant are firmly set in the mud or wet dirt and it gives out elongated stems. The leaves of the plant are attached to these long stems. While the lotus flowers are at all times found above the surface of the water, sometimes even the leaves can be seen floating on the water. The flowers are large, gorgeous and aromatic and they open in the morning. By the afternoon, the petals begin to fall.

As mentioned earlier, the lotus roots remain planted in the mud under the ponds or the river bed. The leaves are found floating on the surface of the water along with the flowers. Generally, the flowers grow on thick stems that raise a number of centimetres higher than the leaves. Normally, the lotus plant grows up to a height of roughly 150 cm and extends up to a maximum area of 3 meters horizontally. However, a number of reports, which have not been verified, state that the plant grows up to a height of more than 5 meters. The leaves of the lotus plant are circular in shape and very large, often growing up to 60 cm (two feet) in diameter. The attractive flowers usually measure 20 cm across.

The fruits of the lotus plants are cone-shaped pods and they enclosed seeds inside the holes found in these pods. It is worth mentioning here that the term ‘Nucifera’ denotes ‘having hard fruit’. When the lotus seeds become mature they become loose inside the pods. Subsequently, the pod tips downwards to the water and releases the seeds on the water surface.

This aquatic plant is indigenous to the regions of Asia as well as Queensland in Australia. Generally, lotus is grown in water gardens. Significantly, the lotus is also the national flower of two Asian countries - India and Vietnam.
