The dichorisandras are usually handled as warmhouse subjects, although some of them may be plunged in the open ground south of Philadelphia. D. thyrsiflora is a satisfactory plant of unusual and interesting appearance, which requires little attention when once well established, and may be relied upon to flower regularly year after year. It needs careful repotting every year at first until a good-sized pot (say 8-inch) is well filled with roots. It then throws up a strong shoot each year about 5 or 6 feet high, unbranched, and with perhaps 8 or 9 leaves near the top. The handsome thyrse of blue flowers gives a color that is rare in the greenhouse. This plant may be the only representative of its interesting order in a private collection. It is willing to be crowded into the background, where its bare stem is hidden, and where the light may be poorest. The stem dies down in the winter time, when water should be gradually withdrawn. Water should be given liberally during the growing season. Of the foliage plants of this genus. D. mosaica is commonest. It is dwarfer, and does not flower so regularly.

Dichorisandra (compounded of Greek words referring to the division of the stamens into two series). Commelinaceae. Tropical perennial herbs, with handsome foliage, often beautifully variegated, and rich blue flowers borne in thyrse-like panicles. Stems simple or branched, erect or partially scandent, the lvs. sheathing at the nodes: lvs. entire, sessile or petiolate, mostly long: sepals 3, distinct, ovate or oblong, green or colored, not equal; petals 3, distinct, wider than the sepals; stamens 6 or 5; ovary sessile, 3-celied: fr. an ovate-3-angled 3- valved caps., few-seeded. — About 30 species in the American tropics. The dichorisandras are usually handled as warmhouse subjects, although some of them may be plunged in the open ground south of Philadelphia. D. thyrsiflora is a satisfactory plant of unusual and interesting appearance, which requires little attention when once well established, and may be relied upon to flower regularly year after year. It needs careful repotting every year at first until a good-sized pot (say 8-inch) is well filled with roots. It then throws up a strong shoot each year about 5 or 6 feet high, unbranched, and with perhaps 8 or 9 leaves near the top. The handsome thyrse of blue flowers gives a color that is rare in the greenhouse. This plant may be the only representative of its interesting order in a private collection. It is willing to be crowded into the background, where its bare stem is hidden, and where the light may be poorest. The stem dies down in the winter time, when water should be gradually withdrawn. Water should be given liberally during the growing season. Of the foliage plants of this genus. D. mosaica is commonest. It is dwarfer, and does not flower so regularly. (Robert Shore.) CH
