| 摘要: |
| 该文首次报道了中国兰科新记录属——腺花兰属(Orchipedum Breda)及其属下新记录种腺花兰(Orchipedum echinatum Aver. & Averyanova),并提供了该属及该种的中文形态描述、该属的分种检索表,以及腺花兰的彩色照片。腺花兰属的主要识别特征为唇瓣基部具2枚纵向褶片,花距呈球形,且距内的两个大型胼胝体上密生许多小的锥状至腺状附属物。该属仅包含4个种,既往仅记录于中南半岛至马来群岛。腺花兰的叶片椭圆形至椭圆状披针形,萼片和花瓣带粉棕色,唇瓣边缘具不规则齿,先端裂片强烈卷曲。此前该种仅在越南中南部有两处记录,本次在中国云南大围山的喀斯特溪谷中发现了其种群,不仅拓展了腺花兰属的地理分布范围,也为中国的野生兰科植物资源提供了新资料。 |

| Abstract: |
| The genus Orchipedum Breda(Orchidaceae)is newly reported in China, with O. echinatum Aver. & Averyanova as the sole species. This study provides detailed morphological descriptions in Chinese for both the genus and the species, along with a key to the species of Orchipedum and color photographs of O. echinatum. The genus is characterized by a lip with two longitudinal keels and a spherical spur containing two large calli, each covered with conical to glandular appendages. Orchipedum was previously known to include only four species, all recorded from the Indochinese Peninsula to the Malay Archipelago. The leaves of O. echinatum are elliptic-ovate or elliptic-lanceolate, and its sepals and petals are olive-pink. The lip is irregularly grooved on the sides, with the epichile distinctly folded inward. Until now, O. echinatum had been recorded at only two locations in central and southern Vietnam. The discovery of new populations in the understory of karst forest near ravines in Dawei Mountain, Yunnan Province, China, expands the known distribution range of Orchipedum and adds valuable data to China's wild orchid resources. |
