Above: Floral organogenesis in Plowmanianthus, a recently described genus of Commelinaceae from the Neotropics. Working clockwise from nine o'clock, can you track the development of the 3 sepals, 3 petals, 3 stamens (note that only three out of six stamen primordia develop to maturity), and 3 carpels? Note that first the sepals and then the petals were dissected away by me successively in the later sequence in order to expose the developing stamens and carpels.
