Abstract

During the first author’s visit to Taiwan in 2002 he checked many fern specimens at several herbaria, i.e. HAST, TAI, TAIF and TNM and found several new taxa, including 6 new records; Pteris dissitifolia Baker, Dryopteris huangshanensis Ching, Dryopteris latibasis Ching, Dryopteris redactopinnata S. K. Basu & Panigr., Microsorium carinatum (W. M. Chu & Z. R. He) S. G. Lu and Polypodiodes chinensis (H. Christ) S. G. Lu and 2 new combinations for Taiwan (Microsorium carinatum (W. M. Chu & Z. R. He) S. G. Lu, and Polypodiodes raishanensis (Rosenst.) S. G. Lu). The description and voucher specimens only for the newly recorded species have been accepted in the present work. Based on the Flora Reipublicae Popularis Sinicae vols. 2-6, there are about 2,600 species of ferns in China. Because different fern arrangement systems are used in Taiwan and Mainland China, lots of different scientific names are applied to the same taxon. The arrangement of families in the present work follows Ching’s system (1978) instead of that in the Flora of Taiwan 2nd ed. Including those newly recorded spesies there are 57 families, 184 genera and 677 species/taxa (including infraspecific taxa) presented in the present work.

中文摘要

第一位著者於2002年前來台灣訪問，並檢視了HAST, TAI, TAIF及TNM的蕨類標本，提出新組合種2種，即龍骨星蕨Microsorium carinatum (W. M. Chu & Z. R. He) S. G. Lu和大葉水龍骨Polypodiodes raishanensis (Rosenst.) S. G. Lu；台灣分佈的新記錄種有6種，即大半邊旗Pteris dissitifolia Baker、黃山鱗毛蕨Dryopteris huangshanensis Ching、闊基鱗毛蕨Dryopteris latibasis Ching、藏布鱗毛蕨Dryopteris redactopinnata S. K. Basu & Panigr.、龍骨星蕨Microsorium carinatum (W. M. Chu & Z. R. He) S. G. Lu和中華水龍骨Polypodiodes chinensis (H. Christ) S. G. Lu。文中除了名錄外，僅針對那6個新記錄種有描述及列出引證標本。依據『中國植物誌』第2-6卷的記載中國地區約有2600種蕨類植物，因海峽兩岸在蕨類植物的分類上是採用不同的分類系統，所以有許多分類群在兩岸是採用不同的學名。本文首次將台灣的蕨類植物按秦仁昌1978年的「蕨類植物分類系統」進行排列；加上此次的新記錄分類群，使得台灣蕨類由原本『臺灣植物誌』第一卷第二版記載的37科、145屬、593分類群增加為57科、184屬、677分類群（包括種下之分類群）。
