台灣特有種植物──小水玉簪（水玉簪科）之辨正

Identity of Burmannia nana Fukuy. & T. Suzuki, A Species of Burmanniaceae Endemic to Taiwan

小水玉簪（Burmannia nana）是福山伯明和鈴木時夫於1936年根據採自蘭嶼島上的一株植物標本所發表的新種植物。Tuyama於1940年將其轉移至Gymnosiphon之下成為G. nanus，但此學名在台灣植物誌第一版中並未被採用。第二作者於蘭嶼大森山重新採獲此種植物，經仔細比對確認與福山伯明的原採集植物相同，且本種與產自西爪哇的Gymnosiphon aphyllus Blume非常相似，因此將B. nana當作G. aphyllus的異名。因為B. nana的模式標本已經遺失，本文重新選定新模式標本T. H. Hsieh 2014存放於台大植物系標本館（TAI）。

Burmannia nana Fukuy. & T. Suzuki was described in 1936 on the basis of one individual collection in Lanyu Island of the southeastern coast of Taiwan. The species was transferred to Gymnosiphon in 1940 as G. nanus (Fukuy. & T. Suzuki) Tuyama, but this name was not adopted in the first edition of Flora of Taiwan. Careful examination of the flowers of this species makes it clear that the species is referable to Gymnosiphon aphyllus Blume which was described from western Java. The species is newly recorded in Taiwan. The type of B. nana Fukuy. & T. Suzuki doesn't exist in Taiwan and Japan, hence the neotype is designated, i. e., T. H. Hsieh 2014 in TAI.
