词汇 zinnia
词源
zinnia. Youth and old age, the zinnia species elegans is called, and anyone who has seen how profusely the annual flower blooms and how quickly it succumbs to the first frost will ap- preciate the folk name. The same applies to all the zinnia genus, which Linnaeus named for Johann Gottfried Zinn, whose life was as bright and brief as his namesake’s. Zinn, a German bota- nist and physician who was a professor of medicine at Gottin- gen, died in 1759 when barely 32. In 1753 he had published what is said to be the first book of the anatomy of the eye. There are about 15 species of the zinnia, which is the state flower of Indiana. Most modern tall forms, with flowers in many colors, come from the Mexican Zinnia elegans introduced in 1886 and growing to heights of about three feet. Another explanation for elegans’s youth-and-old-age nickname may be the stiff hairs on the stem or the coarse plant itself, in contrast to the soft flow- ers, or the plant’s tendency to develop the powdery mildew dis- ease when poorly cultivated. But the spring frost analogy is nicer.
