Fig. 3From: Delayed differentiation of epidermal cells walls can underlie pedomorphosis in plants: the case of pedomorphic petals in the hummingbird-pollinated Caiophora hibiscifolia (Loasaceae, subfam. Loasoideae) speciesSEM images of the adaxial petal epidermis in 5 mm flower buds and mature flowers of L. heterophylla (A, Aʹ, B, Bʹ) and C. hibiscifolia (C, Cʹ, D, Dʹ). Relationship between cell lobeyness (CL) and position of SEM image along the petal midrib (PAMR) (E); relationship between the logarithm of cell area, log(CA), and PAMR (F), and relationship between cell length-to-width ratio (CLWR) and PAMR (G) in 5 mm flower buds and mature flowers of L. heterophylla and C. hibiscifolia. PAMR goes from basal (0), to apical (1)Back to article page
