Mollugo verticillata is the first plant species reported which has characteristics of both C3 (Calvin-Benson pathway) and C4 (Hatch-Slack pathway) plants. This plant species is intermediate between C3 and C4 plants in at least four features generally used to separate those two plant groups: leaf anatomy, cell ultrastructure, photorespiration, and primary photosynthetic products.
