Abstract
THE duckweeds (Lemnaceae) are the smallest flowering plants in the world. Wolffia, the minutest of them, is just about the size of a pinhead. Curiously, flowering of this genus even in Nature has been observed only in a few cases, and many species are known to botanists only by their vegetative characters. Attempts have been made to induce flowering in vitro in several laboratories, but success has so far been achieved in two strains only, one of Lemna gibba1 and the other of L. perpusilla2. The former behaves as a long-day and the latter as a day-neutral plant when grown on a Hoagland-type of medium. Recently we were able to induce flowering in Wolffia microscopica.
