A slightly woody perennial plant of the Velosiaceae family that grows in dry regions. It has many linear, hard leaves clustered around a woody, bifurcated stem. Even after the leaves wither and fall off, the fibrous base covers the stem and persists. A single flower is borne at the terminal end of the flower stalk, with six petal-like tepals. It is a radially symmetrical, bisexual flower. There are about 90 species in South America, but none are particularly useful. The Velosiaceae family is a small group of monocotyledonous plants with about 300 species in four genera distributed in South America (dry regions mainly in Brazil) and Africa (dry regions in central and eastern Africa). It is closely related to the Apiaceae family and is a unique plant in the Liliales order. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
