Ke'cksy. n.s. [commonly kex, cigue, French; cicuta, Latin. Skinner.] Skinner seems to think kecksy or kex the same as hemlock. It is used in Staffordshire both for hemlock, and any other hollow jointed plant.
But hateful docks, rough thistles, kecksies, burs,
Losing both beauty and utility. Shakesp. Henry V.
