菲律賓哈哼花（爵床科）──臺灣新記錄植物

Staurogyne debilis (T. Anders.) C. B. Clarke (Acanthaceae) in Taiwan

菲律賓哈哼花（Staurogyne debilis (T. Anders.) C. B. CIarke）為爵床料（Acanthaceae）之植物，原廣汎分佈於菲律賓群島，如呂宋、巴拉望、岷答那峨、撒瑪、岷多祿等諸島。臺灣首次發現於南部恆春半島南仁山保護區內，位於以殼斗科、八角茴香科、樟科、冬青科、茶科、茜草科等為優勢的常綠闊葉林下，以隱蔽溪澗旁居多。菲律賓哈哼花與分佈於台灣北部之哈哼花極易區別，前者具直立莖，而後者莖極短，葉基生；此外前者之葉片以長橢圓形居多，而後者為倒披針形。本文詳細描述菲律賓哈哼花之形態特徵、生育地狀況，並附其手繪圖及屬之檢索表。對臺灣而言，此新記錄種再度說明恆春半島為熱帶起源植物北移的邊際地帶。
