中文摘要 |
霉草屬(霉草科)植物為腐生性細小草本,甚易被忽略,作者等近年來採集到一些新標本,根據植株外部形態和花粉型態特徵,將台灣產霉草屬植物訂正為四個種,分別為蘭嶼霉草Sciaphila arfakiana Becc.,斑點霉草S. maculata Miers,多枝霉草S. ramosa Fukuy. & T. Suzuki和錫蘭霉草S. secundiflora Thwaites ex Benth.。其中蘭嶼霉草和斑點霉草為新紀錄種,錫蘭霉草新發現於龜山島。蘭嶼島共有三種,為種類最多之處,目前所發現之分布地區均位於台灣島之東部。本文並提供檢索表和特徵描述等資料。 |

Sciaphila arfakiana and S. maculata are new record to Flora of Taiwan and S. secundiflora distributed in Kueishan Island is a new distribution. SEM micrographs of pollen grains, a key to species, species descriptions, and taxonomic notes are provided. |
