臺灣的新紀錄種植物──翅莖半邊蓮（桔梗科：山梗菜屬卵葉半邊蓮組）

Lobelia heyneana (Campanulaceae: Lobelia sect. Stenotium), a newly record species of eastern Taiwan

本文描述臺灣一新紀錄種植物──翅莖半邊蓮，本種之外觀形態與克氏半邊蓮相似，兩者皆屬於卵葉半邊蓮組，但本種的莖具三翅、腋生的花序以及花萼裂片長約花冠合生部分之1／2至2／3等可與後者區分。翅莖半邊蓮廣泛分布於東非至新幾內亞，及喜馬拉雅地區至中國東南部。在臺灣，本種僅見於花蓮及台東之低海拔地區，喜生於潮濕遮陰之生育地。

A newly recorded species Lobelia heyneana Schult. of Taiwan was described in this article. This species is similar to L. cliffortiana L., but could be separated by its 3-winged stem, axillary inflorescence, and length of calyx ca. 1/2~2/3 to the fused part of corolla. This species is widely distributed in tropical Asia and Africa. In Taiwan, this species is only found in low altitude of Hualien and Taitung county, often growing on the moist habitat.
