Chinese broccoli + Swamp cabbage

Kai-lan (also written as gai-lan) is the Cantonese name for a vegetable that is also known as Chinese broccoli or Chinese kale. It is a leaf vegetable featuring thick, flat, glossy blue-green leaves with thick stems and a small number of tiny flower heads similar to those of broccoli. Broccoli and kai-lan belong to the same species Brassica oleracea, but kai-lan is in the group alboglabra [Latin albus+glabrus white and hairless]. Its flavor is very similar to that of broccoli, but slightly more bitter. It is also noticeably stronger. Broccolini is a hybrid between broccoli and kai-lan, produced by Mann Packing Company, Inc.

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.
