| Abstract | Microsporogenesis and male gametogenesis of Musella (Musaceae), a monotypic genus endemic to Yunnan, China, are described for the first time. The anthers are tetrasporangiate. The formation of the anther wall is of the basic type. The mature anther wall consists of an epidermis, an endothecium, many middle layers and a two-layered glandular tapetum with uninucleate cells. The old anther wall consists of an epidermis with annular and helical thickenings and reduced endothecium. Successive cytokinesis follows meiosis of the microspore mother cell thence forming a T-shaped or isobilateral tetrad of microspores. Pollen grains are 2-celled. The generative cell nucleus is clavate in shape. Some special features and relationships between anther structure and pollinator type are discussed. |
