杨树属，属于水杨科。分布在世界各地的有35种。在印度，共有8个分类群，主要分布在喜马拉雅山脉。P. alba L.、P. balsamifera L.、P. deltoides Bartram ex Marshall、P. euphratica Olivo和P. nigra L. var. italica Du Roi等物种局限于印度西北部，而P. gamblei Dode和P. glauca Haines分布于印度东北部。纤毛草壁；在喜玛拉雅山的东部和西部都能找到这种最常见的物种。腋芽和顶芽的性质、蒴果的瓣数是鉴别这些物种的有用特征，但最重要的特征之一是叶片特征，通过叶片特征可以很容易地在野外和非开花状态下鉴别这些物种。讨论了这8种植物的两幅分布图的分布格局。为方便识别，还提供了一个人工钥匙以及树叶字符的插图。
The genus Populus L., belongs to the family Salicaceae Mirb. having 35 species of worldwide distribution. In India, total 8 taxa are known mainly distributed throughout the Himalayas. Species like P. alba L., P. balsamifera L., P. deltoides Bartram ex Marshall, P. euphratica Olivo and P. nigra L. var. italica Du Roi are confined to the north-western parts of India while P. gamblei Dode and P. glauca Haines are found in the north-eastern parts. P. ciliata Wall. ex Royle is the most common species found both in the eastern as well as western Himalayas. Nature of the axillary buds and the terminal buds, number of valves in the capsules are the useful characters for identification of these species but one of the most important feature is the leaf character through which one can easily identify the species in the field as well as while the species are in non-floriferous condition. The distribution pattern with two maps of these 8 species is discussed. An artificial key is provided along with illustrations of leaf characters for easy identity.
