"They have pinnately compound, alternate leaves and whitish or grayish drupes." < This sentence, that begins the third paragraph of this article is not true. Toxicodendron radicans leaves are generally trifoliolate, as stated in the Toxicodendron radicans article. This is stated in the uconn.edu article. Also, take a look at a Poison Ivy plant outside and you will probably see that it's trifoliolate. Therefore, this Toxicodendron genus article may be able to say that most Toxicodendron leaves are pinnately compound. I'm going to edit the article right now.
