AB -This paper is intended for elucidation the anther and pollen wall development of Dumasia miaoliensis Liu and Lu (Fabaceae). The undifferentiated anther is ovoid-shaped and
tetrasporangiated. The anther wall development is basic type, which is composed of an epidermal layer,
an endothecial layer, two middle layers and tapetum. Anther-tapetum is glandular type and its’ cells
are uniseriate and uninucleate. Pollen grains are 6-porate and 2-celled at the time of shedding. Before
protectum development, a glycocalyx layer is deposited on the invaginated plasma membrane,
exclusive of the future apertures. Subsequently, the probacules, arising basally from the plasma
membrane, elongate under the protectum. The foot layer and endexine formation are concomitant with
the callosic wall dissolution. The foot layer is thin and interrupted, but the endexine is thick and
continuous. The intine is initiated in the vacuolated stage.
