LOL regarding being in the same group ... all I know is that they are all in the plant genus Philodendron and that juvenile leaves can be totally different from the mature leaf form! There's more information regarding Florida Beauty here: http://www.exoticrainforest.co...
I've had my Horsehead Philodendron (Philodendron bipennifolium) for at least eight years and the leaf shape hasn't changed much but it stays pretty root bound in it's pot and hasn't been given the means to really take off.
