Abstract

Morphological characters of achenes for nine species of Ranunculus among R. sardous Crantz. is new record to
the flora of Egypt. from Egypt have been investigated using light (LM) and scanning (SEM) microscopy. Carpel
wall structure for some studied species has also been searched. The achene morphology showed considerable
variations in shape, size, surface pattern and wall structure. The macrocharacters as well as microcharacters of
achenes are discussed in relation to taxonomy and proved their significance in the distinction between the studied
species. A key and SEM micrographs of achenes are provided.
