About 60 widely distributed herbs, with tuberous roots, and a spathe rolled in or convolute about the spadix below, and often arched over it: fls. unisexual, the pistillate on the lower part of the spadix, and each consisting of a 1-loculed ovary, and generally ripening into a showy berry. Some species are native, and several of them are hardy in the open; others are cult. under cover, as recommended for Arum (which see). Monogr. by Engler in De Candolle's Monographic Phanerogamarum, Vol. II.
