在西藏八宿县然乌镇安久拉山垭口进行植物多样性调查时,发现一种寄生植物,经过查阅文献、核对模式标本,最终鉴定为列当科(Orobanchaceae)豆列当属(Mannagettaea)植物矮生豆列当(Mannagettaea hummelii H.Smith)。该种分布在中国及俄罗斯(萨彦岭地区),国内记载仅分布在甘肃、青海、四川;西藏为新记录属。该发现丰富了西藏的植物区系,同时将矮生豆列当分布海拔提升至4459 m。凭证标本现存于中国科学院昆明植物研究所标本馆(KUN)。

The investigation of plant diversity in high altitude areas of the Qinghai-Tibet Plateau is insufficient.When we conducted plant diversity survey in Anjiu_La Shan Pass,Ranwu Town,Baxoi Country,Xizang.We found a parasitic plant.After consulting the literatures and checking the typus specimens,we finally identified it as Mannagettaea hummelii H.Smith(Orobanchaceae).Mannagettaea is distributed in China(Gansu,Qinghai,Sichuan)and Russia(Sayanling region).The genus is a new distribution record to Xizang,and the result enriched the flora of Xizang.Meanwhile,it also raised the altitude up to 4459 m.The voucher specimens are kept in the Herbarium of Kunming Institute of Botany(KUN).
