Good day class. I got a little confused about calyx/pistil/stigma relationship and went digging to try to clarify. My real confusion was between pistil and stigma. I've always thought the hairs were pistils. Turns out that pistil is the sum of ovary, style and stigma. So, the calyx houses the pistil which is made up of an ovary and stigma joined by a style that is covered in "stigmatic hairs". This kind of makes the first pic is somewhat incorrect. Anyone see any holes in my thinking?
