FIG. 4. — Flowers types in Moraea and some of their pollinators: A, M. tripetala, with an Iris-type flower, being visited by native Apis mellifera; B, M. villosa, showing prominent "beetle marks" and the black hopliine beetle, Anisonyx ursus, with heavy dorsal load of orange pollen; C, M. polyanthos, typical bowl type flower with stamens and style branches held within the deep floral cup; D, M. marlothii, a stellate type flower with stamens and style branches forming and androgynophore supporting anthers well above the flower.
FIG. 2 in Pollination mechanisms in the African genus Moraea (Iridaceae, Iridoideae): floral divergence and adaptation for pollinators
FIG. 2. — Bowl and salver type flowers in Moraea: A, the bowl-shaped flower of M. collina, with the style and stamens forming a column held within the floral cup; B, M. marlothii, showing entire plant, flower with columnar stamens and style branches, with enlarged detail of the androgynophore; C, D, rotate flowers of M. bifida (C) and M. miniata (D) with the androgynophore much enlarged; E, bowl-shaped flower of M. ochroleuca, showing the fly pollination syndrome, with the perianth lacking nectar guides and radiating veins that secrete nectar.
