Abstract
The primary ridges of the fruit wall bear hairs in two rows and the secondary ridges have spines in a single row. Scanning electron microscopic studies reveal the finer details of the morphology of hairs and spines. The development of hairs and spines is traced out to give a critical morphohistogenic explanation.
