::I have a similar concern about the lead photo, File:Tumbleweed 038 .jpg.  It shows a tumbleweed that could be from a Salsola tragus but that is not evident in the photo and I am not confident of the uploader's ability to identify the species.  The photo description on Commons does not even say the location was North America, and more than one species of Salsola makes tumbleweeds.  Looking at the photo, I am okay with labeling it in the caption as a Salsola but not as a Salsola tragus.
