|Description:||Under a moderately high magnification of 444x, 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" which are actually modified leaves that protect the flowers themselves, are also mistaken for flower petals.|
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.
