Yes it certainly does. It shows the combination of two flowering plants which are nearly identical but apparently different enough to have different names. It tells you what the difference is between those plants (or not). The "Landscape Photos" section can be quite useful for telling the difference between similar-looking plants. This is something I view as quite useful for combining plants in beautiful ways.
Another "comparison" shot which is not so much an example of beautifully planted cacti but intended to illustrate the differences between 3 genera of "old man" cacti :
This I view as belonging to the Landscape Photos section for the same reasons as the picture above.
