The genus Thysananthus of the Lejeuneaceae was first established by Lindenberg in 1844. Three species of Thysananthus were found and described by Y. Horikawa in 1934, namely: T. formosanus, T. fuscobrunneus and T. liukiuensis. As it was understood by Horikawa these species were characterized as follows: T. formosanus had underleaves broader than long, and a curved seta borne at the apex of each lobule; T. fuscobrunneus had underleaves longer than broad and the apex of the lobule was denticulate; while T. liukiuensis had stem leaves entire throughout. Because of these characters Horikawa proposed that they were not only new records for Taiwan but also new to science. |
