Abstract
The follicle ofPergularia daemia (Forsk.) Chiov is ornamented with large number of branched and unbranched soft spines. The spine initiate before anthesis. It develops from the epidermal and subepidermal (ground tissue) layers of the ovary wall. A mature spine consists of an epidermis enclosing parenchymatous ground tissue with vascular strands and laticifers. Two types of trichomes, uniseriate multicellular and multiseriate multicellular, are present on the spine and fruit surface. The cuticle on the fruit surface is thick with a waxy coating. Stomata present on the fruit surface are slightly raised.
