![]() Researchers report that the lotus has the remarkable ability to regulate the temperature of its flowers within a narrow range, just as humans and other warm-blooded animals do. For example, the Chinese variety qian ban lian ("thousand petals lotus") can have between 30 petals in a single blossom and the Japanese variety ohmi myoren ("strange lotus") can have between 20 petals, the greatest number recorded for any species of plant. Some cultivated varieties have extraordinary numbers of petals. They are showy and grow up to 30 cm (12 in) in diameter, but fourteen inches (35 centimeters) has been frequently reported. The flowers are usually found on thick stems rising several centimeters above the leaves. The leaves may be as large as 80 cm (31 in) in diameter. The leaf stalks (petioles) can be up to 200 cm (6 ft 7 in) long, allowing the plant to grow in water to that depth, The peltate leaf blade or lamina can have a horizontal spread of 1 m (3 ft 3 in). The lotus roots are planted in pond or river bottom soil, while the leaves float on the water's surface or are held well above it. According to the APG IV classification, the closest relatives of Nelumbo include the sycamores ( Platanaceae).īotany Lotus plant Carpellary receptacle of lotus nucifera and its relatives in the order Nymphaeles based on anatomical similarities. Older systems, such as the Cronquist system, place N. ![]() lutea, and their extinct relatives belong in Proteales with the protea flowers due to genetic comparisons. While all modern plant taxonomy systems agree that this species belongs in the genus Nelumbo, the systems disagree as to which family Nelumbo should be placed in or whether the genus should belong in its own unique family and order. ![]() ![]() caerulea, the "blue lotus." In fact, several older systems, such as the Bentham & Hooker system (which is widely used in the Indian subcontinent), refer to the lotus by its old synonym, Nymphaea nelumbo. The lotus is often confused with the true water lilies of the genus Nymphaea, in particular N. Nelumbo nucifera is also known as Egyptian bean. It is the national flower of India and Vietnam. 3,000 years) of being cultivated for its edible seeds and is commonly cultivated in water gardens. Today, the species also occurs in southern India, Sri Lanka, virtually all of Southeast Asia, New Guinea, and northern and eastern Australia, but this is probably the result of human translocations. It has a very wide native distribution, ranging from central and northern India (at altitudes up to 1,400 m or 4,600 ft in the southern Himalayas ), through northern Indochina and East Asia (north to the Amur region the Russian populations have sometimes been referred to as " Nelumbo komarovii"), with isolated locations at the Caspian Sea. Therefore, the Chinese regard the plant as a symbol of longevity. Under favorable circumstances, the seeds of this aquatic perennial may remain viable for many years, with the oldest recorded lotus germination being from seeds 1,300 years old recovered from a dry lakebed in northeastern China. During flood conditions, sediments containing these seeds are broken open, and the dormant seeds rehydrate and begin a new lotus colony. While some sprout immediately, and most are eaten by wildlife, the remaining seeds can remain dormant for an extensive period of time as the pond silts in and dries out. Stands of lotus drop hundreds of thousands of seeds every year to the bottom of the pond. Lotus plants are adapted to grow in the flood plains of slow-moving rivers and delta areas. It is sometimes colloquially called a water lily, though this more often refers to members of the family Nymphaeaceae. Nelumbo nucifera, also known as Sacred lotus, Indian lotus, or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae.
