Janis, usually it's not necessary to add name of species in description of photo, because name of taxon is always shown in title of page. It have a sence in just one case, when you have determined the photographed plant as one species, but this species is synonimized in our database with another species.
So, description of photo usually have to have three parts: (1) subject ("What is shown?"), (2) place ("In what geographical region in which environment the plant was found?") and date ("When the photo was taken?").
The order of parts of description is important! It designed specially to make information maximally clear and easy to understand.
