This research focuses on the anatomy and development of floral nectaries in two endemic species, Cardiospermum heringeri and C. integerrimum. The nectary consists of two horn-like lobes,(More)
We investigated the morphology and structure of the floral nectary in 11 Neotropical genera belonging to the subfamilies Dodonaeoideae and Paullinioideae (Sapindaceae) from southern South America representing three tribes (Dodonaeaeae, Paullinieae, and Melicocceae), in relation to other floral traits in species with contrasting morphological flower(More)
