摘要: 对新近产自云南的一种闭鞘姜科地莴笋花属植物——麻栗坡地莴笋花Parahellenia malipoensis Juan Chen, L.Y. Zeng, S. Jin Zeng & N. H. Xia的花部形态进行补充描述。该种在形态上与其他地莴笋花属植物易于差别,如植株不高,茎不分枝,叶片小且有褶皱,花序小,苞片先端有软尖刺,药隔附属体极短且为黄色饰有深红色条纹。

Abstract: The article offers additional floral morphology of a Costaceae species recently described from Yunnan, namely Parahellenia malipoensis Juan Chen, L.Y. Zeng, S. Jin Zeng & N. H. Xia. This species is readily distinguished from other Parahellenia species by distinctive morphological characters, such as very small stature, unbranched stems, small and plicate leaf blades, small inflorescences and bract with a soft spine at apex, small flowers, and notably short yellow anther crest ornamented with dark red lines.

Key words: Costaceae, Parahellenia, morphology, Yunnan, China
