词汇 lespedeza
词源
lespedeza. Japan or bush clover, sometimes called the hoop- coop plant but widely known as lespedeza, is believed to have been brought to America in the early 19th century with a cargo of tea unloaded at Charleston or Savannah. The plant became an escape that was first identified at Monticello, Georgia in 1846, and this initial collected specimen is now preserved at Harvard’s Gray Herbarium. A member of the pea family, lespe- deza has become a very important crop not only for hay and forage but for improving poor soils—it has been shown that corn and cotton crops can be increased 10 to 30 percent by turning under a crop of lespedeza previous to their planting. The slender plant grows to a height of about 18 inches, its leaves divided into three leaflets on many branched stems. The genus Lespedeza, however, contains 125 species, of which Japa- nese clover (Lespedeza striata) is only one. Many of these spe- cies are native to America and it was to them that the botanist Michaux referred when he named the genus in 1803. Lespedeza was named in honor of V. M. de Zespedes, Spanish governor of East Florida in 1795, whose name Michaux misread as Lespedez.
