湖南秋海棠属植物资源全貌及其濒危状况
Germplasm and Conservation Status of Begonia in Hunan Province
摘要
Abstract
Begonia is one of the most diverse plant genera,with the fastest increase in the newly described species over the past two decades.Although Begoniaceae in Flora Reipubicae Popularis Sinicae and Flora of China have been published,the detailed resources of Begonia in China remain unclear,and also the content of Begoniaceae in Flora of Hunan has not been published till now.Through literature and specimen review and ten-year field investigation,a total of 13 species of Begonia are confirmed to be distributed in Hunan Province,including two recently published species(Begonia danxiaensis D.K.Tian & X.L.Yu and B.ruchen-gensis D.K.Tian)and two provincial new records(B.dielsiana E.Pritz.ex Diels and B.cavaleriei H.Lév.).In addition,a new variety,B.danxiaensis var.yongxingensis D.K.Tian,is proposed.Herein,the concise mor-phological description,distribution range,and conservation status evaluation of these species are provided.The key to these species is also provided for easy identification.关键词
