I've added a few more species to the official plant list. I added Joint Vetch (Aeschynomene viscidula) because I finally noticed it growing in the sandhill area. It is a prostrate plant with small flowers (4-5 mm) and could be overlooked easily if you're unobservant, as I have been.
The others are "weeds" that I am just now finding out what they are. I found a great web site listing grasses found in citrus groves, which helped. I need to get down the Extension Office and see what they have.
