Re: [Aroid-l] Philodendron Shift in Leaf Morphology

From: ExoticRainforest <Steve at exoticrainforest.com> on 2009.10.02 at 13:41:53(20137) Phil, it is known as ontogeny and isthe same thing as a child "morphing" into an adult. When a baby isborn it looks little like an adult human but during the child'slife-long ontogeny it changes constantly until reaching adult hood. Even then the young adult continues to "age" and "morph". Plants do the exact same thing and constantly change as they age.. Youstart out with the extremely young sprout which begins to produce leafblades. That then turns into the juvenile form of the plant whenchanges to the pre-adult form and then the adult. As it become anadult it is capable of reproduction but will continue to change as itgrows. Plants high in the canopy look nothing like the same speciesfound near the ground but they are one and the same species.
