Phacellanthus (Orobanchaceae), a Newly Recorded Genus in Taiwan

台灣新記錄屬植物:黃筒花屬

摘要


本文描述台灣新記錄之列當科寄生植物黃筒花(Phacellanthus tubiflorus Siebold & Zucc.);黃筒花屬(Phacellanthus)亦為台灣之新記錄屬。本文並報導其花部解剖及種子、花粉顯微構造與染色體數(2n=42)。黃筒花之族群發現於台灣東北部中海拔針闊葉樹混合林,其植株密被多數鱗狀葉,花序繖房狀,花4-6朵,白色,花筒細長管狀,而與台灣列當科其他全寄生植物如:野菰屬(Aeginetia),草蓯蓉屬(Boschniakia),假野菰屬(Cistanche)和列當屬(Orobanche)容易區別。

並列摘要


A heretofore unrecorded holoparasite Phacellanthus tubiflorus Siebold & Zucc. (Orobanchaceae) was recently discovered in Taiwan. It represents a new genus for the island and is distinguishable from related holoparasitic taxa such as Aeginetia, Christisonia, Boschniakia, and Orobanche by a combination of characters: stems with many scale-like leaves, inflorescence subcapitate or subcorymbose with 4-6 flowers, corolla white, and elongate, slender corolla-tube. Phacellanthus tubiflorus is rare on Taiwan, with no more than two dozen individuals occurring in the cloud zone of a mixed Chamaecyparis/broadleaved forest at 1,800-2,000 m elevation. This paper provides a taxonomic account of Phacellanthus and illustrations to aid in identification.
