Dictionary: Rohrkolben
• cattail [bot.] = der Rohrkolben wiss.: Typha latifolia, Typha angustifolia
• reed mace [bot.] = der Rohrkolben wiss.: Typha latifolia
• bulrush also: bullrush (Brit.) [bot.] = der Rohrkolben wiss.: Typha latifolia, Typha angustifolia

NOTE: This proposal suggests CHANGES to the current LEO-entries:
• cattail also: cat’s tail, cat-tail [bot.] = der Rohrkolben wiss.: Typha (Gattung)
• reed mace [bot.] = der Rohrkolben wiss.: Typha (Gattung)
• bulrush also: bullrush [] [bot.] = der Rohrkolben wiss.: Typha (Gattung)

JUSTIFICATION: “cattail”, “reed mace”, “bulrush”, & “Rohrkolben” are all general terms appropriately applied to all species in the genus Typha. Typha latifolia is the broad-leaved cattail, common cattail, greater bulrush, & greater reed mace, while Typha angustifolia is the narrow-leaved cattail, lesser reed mace, & lesser bulrush. Also, there is no consistent authority that “bulrush” or “bullrush” is strictly or even predominantly British, or that the various forms of “cattail” are strictly or predominantly American or Canadian.
