The woodland lettuce image reminds me about the question of size. These flowers are about 3/8 inch across. In virtually all the images, size reference is lacking. I would much appreciate some feedback. Should I start including a note about size with each image?
Woodland lettuce is in fact a lettuce, and is theoretically edible. But like other wild lettuce, it is very bitter. The name, Lactuca floridana, reminds me that the first time I saw this plant was in Florida, back in BD time.
