印度中央省潘洽瑪生態保留區瓶爾小草屬植物之研究

Studies on the Genus Ophioglossum L. in Pachmarhi Biosphere Reserve, Madhya Pradesh-India

本文乃針對位於印度中央省的潘洽瑪生態保留區（PBR）之瓶爾小草屬植物，就形態分類學、物種組成、分布型及生態學等進行研究。多葉瓶爾小草（O. polyphyllum）為潘洽瑪生態保留區之新記錄種。在本保留區裡，細葉瓶爾小草（O. gramineum）、裸莖瓶爾小草（O. nudicaule）及網脈瓶爾小草（O. reticulatum）呈現地理連續分布。潘洽瑪生態保留區中的瓶爾小草屬植物之分類學的特徵、種間及種內的歧異度、廣泛之分布型，在本文中有較廣泛的討論。

The morphotaxonomy, species composition, distributional pattern and ecological studies of the genus Ophioglossum L. (Adder’s tongue) in Pachmarhi Biosphere Reserve (PBR) of Madhya Pradesh have been accomplished. Ophioglossum polyphyllum A. Braun ex Seubert have been recorded for the first time which is a new addition to the pteridophytic flora of PBR. However, Ophioglossum gramineum Willd, Ophioglossum nudicaule L. and O. reticulatum L. has shown extended range of trans-geographical distribution within the Biosphere Reserve. The taxonomic characters, diversity between and within the species, and habitat of growth across the Biosphere Reserve have been extensively discussed.
