The small genus Allagoptera (Arecaceae) includes six South American species. Their leaves have several anatomical characters that remain unexplored. We provide a detailed description of the leaf anatomy of Allagoptera, using 128 characters, and an identification key. Given the gradual size variation in the mesophyll cells in some species, a new classification of 'gradual dorsiventral mesophyll' is proposed here. We report for the first time 'subsidiary ledges' in the stomatal complex of Arecaceae. We propose using 'bulliform cell' for the swelling cells along the midvein in Arecaceae.
