The Alvin Sun-Advertiser
reports on a rare hybrid found by a local gardener a tomato-cucumber. They're calling it a 'Cumato':
Mario Rodriguez may have made history. According to Rodrigues, he found a specimen on a cucumber plant that was situated close to his tomato vines, Rodriguez plucked the interesting vegetable that looked like a normal tomato (right) but was attached to one of his cucumber plants. He has yet to name the hybrid and there is apparently no record of such a plant.
Unfortunately the photo of Rodriguez holding the cumato is pretty bad. You can't see any details of the rare vegetable. I also want to know if he's cut it open. What's inside of it? Is it simply a tomato, or is it a combination of both? For now I'm skeptical of this. (Thanks to 't' for the link)
