Shayeg, I'm going to say you have a watermelon. For several reasons. The plant in your image displays classic watermelon leaves, vines, and tendrils. There are two places, one on the left and the other on the right that you see what appear to be the heads of two different vines- hairy looking things with two tendrils that you find at the leading end of a vine. Now look at the right side of the image about middle where there is a fork in the vine. Follow the bottom fork down to where you see a blurry yellow spot. Would need a clearer image to verify that that is indeed a flower. But, watermelon flowers are yellow. The most damning evidence- go back to the flower and follow the vine back up about halfway to the fork mentioned before. Enlarge the image and at the juncture of the vine and a leaf you see a very small watermelon newly forming. It looks about the size of a grape in comparison to the rest of the plant and is on a stem about an inch or two long. The solanum rostratum mentioned by Ron is similar in appearance to Watermelon, but I believe it has numerous spikes and thorns on the vine that I do not see in your picture. Hence it's nickname "buffalo bur". If you could, show us another picture of the plant from a different angle. Perhaps a close up of the end of a vine and the newly formed fruit I mentioned. (if it's still there- the fruits sometimes dont make it at that early stage and you must wait on another one two form elsewhere on the vine). This could possibly be wishful thinking on my part as I grow lots of melons and just love them, but judging from the image I'm going to say that's what it is. Would like to see some others' opinions and definately another picture if you could. Did you eat a watermelon around that area last year or perhaps throw a piece of rind with some seed stuck to it? I just looked again at the picture, and I'm convinced. I'd bet money you're a watermelon farmer.
wow thankyou very much both of you i will take another pic and put it on here. I planted one watermelon plant and it is no where near this one we are trying to identify
