摘要


臺灣的臺灣新耳草(Neanotis formosana (Hayata) Lewis)以往的分類文獻中將其處理為涼喉茶(N. hirsuta (L. f.) Lewis)。本研究確定臺灣新耳草的存在,並進一步確認涼喉茶的特徵。臺灣新耳草的特徵為花序頂生,2~10朵叢生於5~10 mm的總花梗上,花徑大於5 mm;而涼喉茶則是花序腋生稀頂生,1~4朵花叢生於0~4 mm的花梗上,花徑小於3 mm。本文並提供它們的分類處理、繪圖、照片以供參考。

In this paper, we clarify the identify of N. formosana in the flora of Taiwan and further document N. hirsuta in Taiwan. Neanotis formosana is characterized by a terminal inflorescence, cyme, 2~10-flowered in fascicles with peduncles 5~10 mm long; and flowers > 5 mm wide. Neanotis hirsute has an axillary inflorescence, rarely terminal, 1~4-flowered, with peduncles 0~3 mm long; and flowers < 3 mm wide. Taxonomic treatment, line drawings, and photographs are provided herein.
