While we were engaged in revising the family Rubiaceae, we found that in Taiwan the genus Lasianthus is especially rich in species as compared with the other genera of the same family, which makes the identification of species a rather troublesome work. Most of the species of the said genus are commonly distributed under the tropical and subtropical rain forests in the whole island and adjacent areas. In 1906, Matsumura and Hayata first listed 7 species in their ''Enumeratio Plantarum Formosanarum''. After thirty years, namely in 1936, 10 species were found both in Masamune's ''Short Flora of Formosa'' and in Kanehira's ''Formosan Trees, Rev. Ed.'' Near the end of the Second World War (1944), a paper on the Genus Lasianthus of Formosa (Notae ad Plantes, Generis Lasianthi Formosae) was published by H. Simizu in Trans. Nat. Hist. Soc. Formosa, in which 11 species were dealt with. Among them, 6 species were described as new. |
