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
