Flower Symmetry<\/strong><\/h2>\n

by Scott Namestnik, snamestnik@orbisec.com<\/a><\/h2>\n

Last month in Your Daily Dose of Botany<\/em>, I mentioned that the disc florets of composites are radially symmetrical.\u00a0 Another name for this floral morphology structure is \u201cactinomorphic.\u201d\u00a0 Many plant species have flowers that can be described as actinomorphic.\u00a0 If you could cut the flower in half in two or more planes and have identical-looking halves, you have an actinomorphic flower. As an example, think of a rose as a plant with actinomorphic flowers.<\/p>\n

\"An<\/a>
An actinomorphic flower of pasture rose (Rosa carolina); cutting the flower in half in any of the directions results in identical halves.<\/figcaption><\/figure>\n

So, if many<\/em> plant species have actinomorphic flowers, what do the rest have?\u00a0 If a flower can only result in identical halves if it is cut in one specific plane, and cutting the flower in half in other planes does not result in identical halves, the flower is said to be zygomorphic, or bilaterally symmetric.\u00a0 Orchids, for example, have zygomorphic flowers.<\/p>\n

Although there is unimaginable diversity in the shape, color, and structure of flowers, all flowers can be described as either actinomorphic or zygomorphic.\u00a0 Watch for the different symmetries in flowers the next time you\u2019re out on a hike.<\/p>\n

If you have a question about plant terminology or morphology that you would like answered in a future edition of this column, send me an email at snamestnik@orbisec.com<\/a>. I may not be able to address all requests given the space allotted for this column, but I will answer those that I can.<\/p>\n
