Tall hispid herbaceous plants, remarkable for their large bold foliage. Leaves alternate, simple, more or less toothed or lobed, becoming gradually smaller upwards. Flowers in gyrate cymes, resembling those of Eutoca in structure. The few species known are natives of tropical America, and, therefore, only available for Summer decoration. This genus was named in honour of Wigand, formerly Bishop of Pomerania.
