印度兩種易混淆的寶石蘭（蘭科斑——葉蘭亞族）

Two Frequently Confused Species of 'Jewel Orchid' (Orchidaceae - Goodyerinae) from India

白肋線柱蘭與芳線柱蘭是兩種不同的陸生蘭，但最近在印度的文獻中卻常常將其搞混而錯誤回報。本文強調研究此兩物種的模式標本在鑑定過程中的必要性，以確保兩物種之身分確定，因鑑定上的錯誤不斷被重複，很有可能造成此兩物種身分的模糊。

Zeuxine goodyeroides and Zeuxine nervosa are two distinct species of terrestrial orchids but confused and misreported in some recent Indian literature. The present communication emphasizes the need of study of type specimens for fixing identity of species. A mistake repeated several times will have a chance to obscure the correct identity of a species.
