(Vigna unguiculata subsp. sesquipedalis)
Although yardlong beans were included in the previous post, they are more usually known here as 豆角 (Mand: dòu jiǎo; Cant: dau6 gok3).
Alternative English names include asparagus bean,long-podded cowpea, Chinese long bean, bodi/bora,] snake bean, and pea bean.
QuoteDespite the common name of "yardlong", the pods are actually only about half a yard long, so the subspecies name sesquipedalis (one-and-a-half-foot-long; 1.5 feet (0.50 yd)) is a more accurate approximation.
