Tetradymia (four together, from Greek words, referring to the 4-fld. heads of one species). Compositae. A genus of low rigid shrubs of the composite family native to the arid regions of W. N. Amer. Herbage covered with dense matted wool: lvs. alternate, often modified into spines. The original species, T. canescens, is the best known. Its heads have only 4 fls. They are yellow and about 1/2 – 3/4 in. long. This plant was offered in the E. in 1881 by western collectors but has no horticultural standing and is now probably not in cult. in Amer. There are about a half-dozen species, but not known horticulturally. CH The above text is from the Standard Cyclopedia of Horticulture.
