中文摘要 | 本文處理臺灣產懸鉤子屬植物的分類,更新為40 個分類群(34 種、3 變種與3 雜交種), 其中Rubus croceacanthus × corchorifolius 與Rubus rosifolius × fraxinifolius 為首次記載。臺灣產懸鉤子屬植物當中,以虎婆刺 (Rubus croceacanthus H. Lév.) 的形態最為多變,將來仍須進一步研究。臺灣植物誌第二版中的許多學名在此被處理為同物異名,許多分類群也被加以訂正。重新確認裂葉懸鉤子 (Rubus howii Merr. & Chun)、細葉懸鉤子 (Rubus linearifoliolus Hayata) 與小梣葉懸鉤子 (Rubus parvifraxinifolius Hayata) 存在於臺灣,清水懸鉤子 [Rubus pseudoacer Makino ssp. flexuosus (Y.-C. Liu & F.-Y. Lu) H. Ohashi & C.-F. Hsieh] 則併入Rubus pseudoacer Makino,並確認此分類群不產於臺灣。另外,根據形態特徵將小梣葉懸鉤子之學名處理為Rubus × parvifraxinifolius Hayata,推測其為刺莓 (Rubus rosifolius Sm.) 與細葉懸鉤子 (Rubus linearifoliolus Hayata) 之雜交種。本文首次描述裂葉懸鉤子在原始文獻缺乏之聚合果特徵,此外提供了各分類群之檢索表、同物異名與特徵描述,並加上了物候、染色體數、地理分佈與檢閱標本等資訊。 |
英文摘要 | The genus Rubus L. in Taiwan is taxonomically revised based on morphological and phytogeographical patterns. Forty taxa (34 species, 3 varieties, and 3 hybrids) of the genus are recognized, including two new hybrid species R. croceacanthus × corchorifolius and R. rosifolius × fraxinifolius. Among the Rubus taxa in Taiwan, R. croceacanthus H. Lév. exhibits tremendous variation and we do believe that more investigations are needed in the future. Several taxa described in the Flora of Taiwan, 2nd ed. are treated as synonyms of other species, and several taxa in Taiwan are revised. The existence of R. howii Merr. & Chun, R. linearifoliolus Hayata, and R. parvifraxinifolius Hayata in Taiwan are reconfirmed, we described R. howii fruit information which was absent in original literature; and the third taxon is treated as a natural hydrid R. × parvifraxinifolius Hayata which putatively derived from R. rosifolius Sm. and R. linearifoliolus based on intermediate morphology and the scarcity of fruit set. Rubus pseudoacer Makino ssp. flexuosus (Y.-C. Liu & F.-Y. Lu) H. Ohashi & C.-F. Hsieh is treated as synonym of R. pseudoacer Makino and is excluded in Taiwan. A key to the taxa, synonyms and taxonomic descriptions of each taxon are presented. Moreover, information about phenology, chromosome number, distribution and specimens examined for each taxon are also provided. |
