Monochoria korsakowii (flowering plant)
Archaic name for a species of water plant; also referred to as 水葵 (みずあおい). Not in modern common use.

古い本草書には「水葱」をなぎと読ませ、水辺の草として記している。
Old herbal texts record 水葱 as なぎ, describing it as a waterside plant.
Modern common name for the same or a closely related plant; 水葱 is the archaic equivalent.
The derivation of なぎ is uncertain; the kanji 水葱 and 菜葱 are likely ateji based on the plant's aquatic habitat and onion-like leaves.
