A small trade is done in the hardy species of Arum, chiefly amongst those who love curiosities. A. crinitum, the Dragon's Mouth, is an extraordinary-looking Corsican plant, 18 in. high, with evil-smelling flowers, having a large hairy spathe and spadix. A. Dracunculus is another curiosity, 2-3 ft. high, with deep purple or claret spathes. A. palestinum has deep velvety-purple spathes. The common British Arum, A. maculatum, known also as "Lords and Ladies" is well known.
