| Ipsea (fancied resemblance to ips, a cynip insect or a worm). Orchidaceae. Two or 3 terrestrial E.

− | Low, spreading, climbing or erect herbs or subshrubs: lvs. stalked, opposite, the margins not toothed in the domestic species: fls. very small, bracteate, in axillary or terminal panicles, perfect or imperfect (plants sometimes dioecious), the perianth of one series terete, 5- parted, with ovate-oblong segms.; stamens 5; style short or none, the stigmas 2 or 3: fr. a utriculus.—Species 20-25 in Trop. and Subtrop. Amer. Two or 3 species are in common cult, as bedding-plants, because of their highly colored lvs. and sts. The first of these to be intro. was described before the fls. were known and it was referred to Achyranthes (A. verschaffeltii), but in that genus the anthers are 2- loculed, whereas in Iresine they are 1- loculed. To gardeners they are still known as Achyranthes.

− | Because of ease of propagation, ability to withstand sun and shearing, and the bright colors, the iresines are amongst the most popular bedding - plants. Few plants are easier to grow. Stock plants are kept over winter in a cool temperature (as in a carnation house), and in February and March they are given more heat and moisture, and cut back, to get cutting wood. Cuttings root quickly in any good cutting-bed. For mass bedding, plants are usually set 6 to 10 inches apart. They will not withstand frost.
