摘要：Genus Dendrobium orchid is a genus from spermatophyte division is a category of plants that grow from seed. Seed plants have a flower as a means generative outgrowth. The generative outgrowth from the flower it means incorporation between the male gamete cells and female gamete cells. The female gamete cells in plants produced by the pistil,meanwhile the male gamete cells called serbuk sari or pollen. Dendrobium genus is one of of Indonesian’s assets estimated at 275 species. This research aims to determine how the ultrastructure of genus Dendrobium orchid pollen from ten species were observed using SEM. This research using descriptive-qualitative. The research method using selective media. The results showed that pollen unit for all of the species that is category of pollinia,while the polarity of the pollen is apolar. Types of tenth aperture where had researched had aperture with the irregular patterns and more than 6 called colpate. the shape of pollen from all species that had researched are subprolate to the prolate and the pollen size is in the category of the minuta to the media. Ornamentasi pollen or skluptur pollen is not identify because the size of pollen is too small,the surface of pollen is less obvious. Learning sources used atlas..
