泰國蘭科植物誌（二）

Notes on the Orchid Flora of Thailand (II)

泰國植物誌增加三種新紀錄的蘭花。其中Macodes petola發現於泰國南部，與已知有此分佈的馬來西亞邊界緊鄰。而Cheirostylis octodactyla的發現使其分佈範圍向西延伸，它之前知道分佈於菲律賓北部，臺灣與越南北部。最近發現之Zeuxine bidupensis，之前以為是越南特有，不僅在形態上也在地理上近似於West Bengal之Z. pantlingii。

Three orchid species are newly recorded for the flora of Thailand. The discovery of Macodes petola in the southern part of Peninsular Thailand, adjacent to known occurrences across the Malaysian border, was expected. On the other hand, the find of Cheirostylis octodactyla in Thailand considerably extended the known range of this species to the west, as it was previously known only from the northern part of the Philippines, Taiwan and (through a single collection) from northern Vietnam. The recent discovery of populations of Zeuxine bidupensis in Thailand suggests that this species, hitherto considered endemic to Vietnam, does not only have morphological, but also geographic affintities to the little known Z. pantlingii from West Bengal.
