杨亚科植物的分类与分布

On the Classification and Distribution of the Subfamily Populoideae(Salicaceae)

    摘要
  • 摘要: 杨亚科(Populoideae)植物自然分布于热带非洲和大约从北纬19°~70°度的北半球,由胡杨属(Balsamiflua)和杨属(Populus)2个属所组成。胡杨属间断分布于赤道非洲、古地中海地区和墨西哥,包含2个组(胡杨组、墨杨组)和约3个天然种。杨属分布于欧洲、亚洲、非洲(北缘)和北美洲的广大地区,包含大叶杨亚属(Subgen.Leucoides)(大叶杨组)、杨亚属(Subgen.Populus)(青杨组、黑杨组、杨组)2个亚属和约52个天然种。拟定了杨亚科属的检索表、胡杨属组和种的检索表、杨属亚属和组的检索表以及杨属中各组种的检索表。提供了一个杨树种类目录,包括它们的正名、异名、文献引注和地理分布等。

     

    Abstract: The subfamily Populoideae(Salicaceae) naturally distributes in tropical Africa and in the Northern Hemisphere from about 19°to 70°north latitude,and consists of two genera,i.e.Balsamiflua and Populus.The genus Balsamiflua,with two sections,i.e.sect.Balsamiflua et sect.Abaso and about 3 natural species,disjunctively disperses in equatorial Africa,Tethyan region and Mexico.The genus Populus contains two subgenera,i.e.subgen.Leucoides(incl.sect.Leucoides) et subgen.Populus(incl.sect.Tacamahaca,sect.Aigeiros et sect.Populus) and about 52 natural species,and widely ranges in Europe,Asia,North America et the northern fringe of Africa.A key to the genera of Populoideae,a key to the sections et species of Balsamiflua,a key to the subgenera et sections of Populus and the keys to the species of each section in Populus are drafted.A checklist of the poplar species is provided,including their correct names,synonyms,bibliographic references,geographic distributions etc.
