摘　　要：本研究报道了中国西藏墨脱发现的兰科(Orchidaceae)一新记录属——短头兰属(Trachoma Garay),该属与管唇兰属(Tuberolabium Yamamoto)相近,区别在于前者花朵簇生于短的花序上,短寿,分批开放,花粉团为完整的球形或具不明显的沟纹;后者花朵着生于长的花序上,花期较长,同时开放,花粉团深裂,由透明膜隔开。Trachoma Garay,originally described from northern India,was recently collected from Motuo,Tibet Auto-nomous Region,China.The flowers are similar to those of Tuberolabium Yamamoto,but in that genus the flowers open simultaneously along an elongate rachis and with deeply cleft separated by a hyaline flange poliionia,whereas in Trachoma they open in successive clusters on an abbreviated rachis and with entire or obscurely sulcate pollinia.
