arisæma

from The Century Dictionary.

• noun A genus of about 50 widely distributed species of tuberous-rooted herbs of the family Araceæ. The tropical species are sometimes grown as hothouse subjects; but those commonly known are the two native species, A. Dracontium, the dragon-root, and A. triphyllum, the Indian turnip or jack-in-the-pulpit. These two species are easily transferred to the garden, and they can be grown in pots indoors for very early spring bloom.
