Figure 1From: The double-corolla phenotype in the Hawaiian lobelioid genus Clermontia involves ectopic expression of PISTILLATA B-function MADS box gene homologsGroundplan diversity in representative Clermontia species. Floral morphology of the standard sepal-petal species (A) Clermontia arborescens and (B) C. fauriei and double-corolla species (C) C. parviflora and (D) C. oblongifolia are shown. C. arborescens and C. fauriei exhibit small green sepals (s) in the outer perianth whorl and five large showy petals (p5) in the inner perianth whorl. C. parviflora and C. oblongifolia bear 10 petal-like organs (p10) in both perianth whorls. Photos courtesy of Anne-Cathrine Scheen (A), John Game (B) and Jupiter Nielsen (C,D).Back to article page
