Abstract

Cotoneaster dammeri Schneid. is a new record to the flora of Taiwan. It was found at Mt. Hohuan of Taroko National Park, and in the Tatachia area of Yushan National Park, at elevations between 2,600 and 3,000 m. This species is similar to C. morrisonensis Hayata, an endemic species of Taiwan. However, they can be distinguished by size of leaves, number of styles and pyrenes, and length of peduncles.

中文摘要

本文介紹台灣產舖地蜈蚣屬（薔薇科）一新紀錄種－矮生栒子（Cotoneaster dammeri Schneid.）。矮生栒子目前發現於太魯閣國家公園合歡山區及玉山國家公園塔塔加地區，海拔2,600-3,000 m。在形態上本種與台灣的特有種玉山舖地蜈蚣（C. morrisonensis Hayata）近似，但可從兩種之葉型大小、花柱與果核的數量及花梗的長度區分之。
