Lotus + Swamp cabbage

Nelumbo is a genus of aquatic plants with large, showy flowers resembling the water lily, but not closely related to it. It is commonly called lotus, though this name may be applied to other genera, and there is an unrelated genus Lotus. The generic name is derived from the Sinhalese word Nelum. There are only two known living species in the genus. The sacred lotus (N. nucifera) is native to Asia, and is the better known of the two. It is commonly cultivated, and also used in Chinese medicine and cooking. This species is the national flower of India and Vietnam. The American lotus (N. lutea) is native to North America and the Caribbean. Horticultural hybrids have been produced between these two geographically separated species. A third, extinct species, N. aureavallis, is known from Eocene fossils from North Dakota, United States.

Ipomoea aquatica is a semiaquatic, tropical plant grown as a vegetable for its tender shoots and leaves. It is found throughout the tropical and subtropical regions of the world, although it is not known where it originated. This plant is known in English as water spinach, river spinach, water morning glory, water convolvulus, or by the more ambiguous names Chinese spinach, Chinese convolvulus, swamp cabbage or kangkong in Southeast Asia. Occasionally, it has also been mistakenly called "kale" in English, although kale is a strain of mustard belonging to the species Brassica oleracea and is completely unrelated to water spinach, which is a species of morning glory. It is known as phak bung in Thai, rau mu?ng in Vietnamese, trokuon in Khmer, kalmi shak in Bengali, kangkung in Malay and Indonesian and hayoyo in Ghana.
