茨藻属有约35种，广泛分布于全球各地，也有的分类学家单独将其列为茨藻科。
茨藻属植物为沉水草本植物，可以生长在淡水或咸水中，茎纤细有分枝；叶对生无柄，线形，有齿；花小，单性同株或很少异株，腋生，雄花几乎无柄，包藏在一个瓶状的苞内，花被2裂；雄蕊1，雌花无花被；果实不开裂，常包藏于叶鞘内。
1998年的根据基因分类的APG 分类法和2003年经过修订的的APG II 分类法将其列入泽泻目中。

Najas, the waternymphs or naiads, is a genus of aquatic plants. It is cosmopolitan in distribution, first described for modern science by Linnaeus in 1753. Until 1997, it was rarely placed in the Hydrocharitaceae, and was often taken as constituting (by itself) the family Najadaceae.
