From: The fruit morphometric variation and fruit type evolution of the stone oaks (Fagaceae, Lithocarpus)
The intraspecific variations of fruit morphological dimensions within the two fruit types. a the seed coverage by pericarp and receptacle of the AC species. b the seed coverage by pericarp and receptacle of the ER species. c the volume of pericarp and receptacle of the AC species. d the volume of pericarp and receptacle of the ER species. Each circle represents a single fruit, and colors correspond to the 51 AC and 11 ER species with no less than eight fruits respectively
