台灣產蠕蟲枝藻科植物之形態研究

Abstract

台灣產蠕蟲枝藻科植物（Helminthocladiaceae）共七屬十七種，其中包括一個新種Dotyophycus abbottfi，二個新記錄屬Helminthocladia，Trichogloea及五個新記錄種，Helminthocladia australis Harvey, Liagora amplectens Abbott, L.robusta Yamada, L. segawai Yamada, Trichogloea requienii (Montagne) K?tzing。並根據植物外部形態及內部構造作屬及種之檢索表。 對本科植物每一個種之外部及內部之各結構均作形態之研究及描述，並特別著重果卵胞枝之起源及成孢體絲之發育。以探討其演化上的意義及各屬之分類地位。

A morphological study was made on the family Helmintho-cladiaceae of Taiwan, which shows that there are 7 genera, 17 species, including one new species Dotyophycus abbottii; 2 new record genera, Helminthocladia & Trichogloea; and 5 new record species, Helminthocladia australis Harvey, Liagora amplectens Abbott, L. robusta Yamada, L. segawai Yamada, Trichogloea requienii (Montagne) K?tzing. Key to genera and species are also given. In the present report, both external and internal morphology are desoribed, with special reference to the origin of the carpogonial branch and the development of gonimoblast filaments. The significance of the evolution and taxonomic position in genera are also discussed.
