Lilligant is the transgender pokemon. I was just looking at a picture of one and I noticed that even though they're a 100% female species the flower hat they have only has male reproductive organs.
I am prett sure it is an oversight lol. Most people jsut assume a plant is a plant and move on lol. ((and yea... don't a lot of flowers technically have both all the time? I know quite a few flowers self-pollinate.))
