| Abstract: | The pollen grains of 8 genera, 22 species, 3 varieties in Chinese Thymelaeaceae were observed by means of light and scaning electron microscope in the present paper. Pollen morphology of the family Thymelaeaceae is typically stenopalynous. Grains pantoporate, spheroidal or subspheroidal, diameter 18.2-39.0β; pore number 4-24, pores rounded. pores diameter 0.6-3.9β, distance between pores 2.0-10.4μ; exine 2.0-5.2μ thick; sexine reticulate-croton pattern or tubercular. Based on types of ornamentation, pollen grains of the family Thymelaeaceae were divided into two types-the tubercular and reticulate croton pattern. In addition, the reticulate-croton patterrs and systematic position of the family Thymelaeaceae in the angiosperm were discussed. |
