A REVISION OF THE GENUS UTRICULARIA IN CHINA

In the present paper. the genus Utricularia in China is revised, some of taxonomic confusion are cleared, about 500 chinese specimens examined from 25 herberia are cited and a key to the 17 species recognized by the author is provided. U. minutissima, U. limosa and U. punctata are newly recorded from China. The seeds of U. salwinensis Hand.-Mazz. are reported for the first time.A sample (T. T. Yu 20255, collected in Gongshan-N. W. Yunnan, China)has a narrowly oblong seed (l-1.2 mm long, including its hairs) and apink corolla. The seed has at each end a tufu of long hairs at least balf aslong as the seedself. The specimens, Van Steenis 8598 and De Wild 15258, collected from N.Sumatra, Indonesia, identified by P. Taylor as U. salwinensis in FloraMalesiana (1977), have a white corolla rand a smaller ovoid (c. 0.5 mmlong) and densely short-echinate seed and might represent a new species.
