Wikipedia: Bok choy
Bok choy (American English), pak choi (British English), pichay/petsay (Philippine English), or pok choi (Brassica rapa subsp. chinensis) is a type of Chinese cabbage. Chinensis varieties do not form heads and have green leaf blades with lighter bulbous bottoms instead, forming a cluster reminiscent of mustard greens.
