title: [Seed morphology of 17 Dendrobium species from Yunnan].
abstract: Seed morphology of 17 Dendrobium species from Yunnan were observed under light microscope and environment scanning electron microscope and 16 of them were reported first time. All seeds were yellow and fusiform, but big differences existed in sizes of seeds and embryos, which were not significantly related to the division of sections under Dendrobium. Dendrobium seed consisted of embryo and testa with flocs on its cell walls. The density and length of flocs were different among the sections under Dendrobium.
