ID#:8771
Description:Magnified 119x, this scanning electron microscopic (SEM) image revealed some of the morphologic ultrastructural surface details of one of the very small flower buds clustered in the center of a white dogwood flower, Cornus florida. Due to the extremely small size of the centrally located clustered flowers, the larger colored "bracts" that are actually modified leaves, which protect the flowers themselves, are also mistaken for flower petals. If you look carefully, you'll notice that the small flower petals come together in a confluence at its tip, and will burst open at this point when the flower blossoms.
The specimen from which these micrographic images were obtained was found on the grounds of the Decatur, Georgia suburbs in the month of April. The floral elements seem to bud from newly developing branches. In the Decatur area, the dogwood trees are quite abundant, some displaying white bracts, while others displaying bracts of pink.
