菱叶卫矛 Euonymus tashiroi Maxim.

常綠小灌木;小枝方形,4棱明顯呈窄邊狀。葉薄革質,近菱形或菱狀橢圓形,長4—8釐米,寬2—4釐米,先端漸尖,基部窄楔形,邊緣下卷,有疏淺鋸齒,側脈疏生,最下1對靠近葉緣,在兩面均不甚明顯;葉柄短,長2—5毫米。聚傘花序短,1—2腋生,1—3花;花序梗長在1釐米以下;花白綠色;花瓣邊緣波狀;雄蕊花絲極短,花藥2室,平展,圓孔狀開裂;子房具短花柱。蒴果4深裂,常只1—2裂片發育成熟;種子每室1個,室軸著生,假種皮舟狀蓋於外側。

我國臺灣省特產,分佈於台東台中等地。生長山地,海拔1 000米左右處。模式標本采自臺灣。

李惠林、侯定等曾把本種轉入溝瓣屬,但本種胚珠軸著生,果熟時分佈為4個不等的深裂片,顯然是衛矛屬植物。
