摘要

泡葉栒子(Cotoneaster bullatus Bois)過去在台灣被鑑定為小西氏栒子(C. konishii Hayata)，甚至發表處理成工藤氏石楠(Photinia kudoi Masamune)或工藤氏老葉兒樹(Pourthiaea kudoi (Masamune) Masamune)。本文確認泡葉栒子產於台灣，並將Photinia kudoi Masamune及Pourthiaea kudoi (Masamune) Masamune處理為其新異名，文中並提供其分類處理、形態特徵描述、彩色照片及繪圖以供參考。在形態上本種近似小西氏栒子，但可由兩者的葉形及花序小花的數量區分之。泡葉栒子葉較大(5~13×1.5~5.5 cm)、葉面有明顯泡狀隆起及花序小花7~21朵，與小西氏栒子葉較小(1.3~5×1~3.5cm)、葉面無泡狀隆起及花序小花3~5朵稀7朵可以區分。

In Taiwan, Cotoneaster bullatus Bois was treated as a new species, Photinia kudoi Masamune, and was identified as C. konishii Hayata. In this paper, we clarify the identity of C. bullatus Bois in the flora of Taiwan. Line drawings, color photos, and a taxonomic description are also provided in the paper. Photinia kudoi Masamune and Pourthiaea kudoi (Masamune) Masamune are designated as 2 new synonyms of C. bullatus Bois. This species, C. bullatus Bois, is similar to C. konishii Hayata, but they can be distinguished by the floweret number of the inflorescence and the shape of the leaves. Cotoneaster bullatus has biggish leaves (5~13×1.5~5.5 cm), the upper surface is conspicuously bullate, and the inflorescence is 7~21-flowered, which differ from these of C. konishii which has smaller leaves (1.3~5×1~3.5 cm), the upper surface is not bullate, and the inflorescence is 3~5-flowered (rarely ~7).
