Comparative hypanthium and androecium development in Eugenia and differential rate of pollen sac maturation (in orange) according to number of stamens per flower. (A, B) Androecium initiation and hypanthium development of E. angustissima, showing two or three loose stamen whorls forming on the expanded hypanthium. (C) Early maturation of pollen sacs in E. uniflora. (D, E) Androecium initiation and hypanthium development of E. dichroma, showing five loose stamen whorls forming on the hypanthium. (F) Pollen sacs in maturation process in E. longiracemosa. (G, H) Androecium initiation and hypanthium development of E. azurensis, showing eight loose stamen whorls forming on the hypanthium. (I) Late pollen sac maturation in E. stipitata. (J, K) Androecium initiation and hypanthium development of (J) E. gacognei and (K) E. paludosa, showing a gap between the development of the first and five following stamen whorls. (L) Pollen sac maturation in E. paludosa, showing anthers from the first staminal whorl in a more advanced state of development. A(ant), anther; G, gynoecium; P, petal; H, hypanthium. Scale bars: (A–D, F, G, I–L) = 100 µm; (E, H) = 200 µm. Colour coding in online version: sepals, green; corolla, red; androecium, yellow; gynoecium, blue.
