The results show that the pollen grains are globose to long globular in shape. The maximum and m inimum P /E values are Yucca sm alliana Fern. and O sm anthus fragrans ( Thunb. ) Lour. The maximum pollen grain is L uffa cylindrica (L. ) Roem., and the m inimum is C lad rastis w ilson ii Takeda. of apertures include monosulcate, 3 6 colpate, The types irregular pantocolpate, tricolporate, 2 4 porate and pantoporate. The ornam entation of exine are sp inulose, finely reticulate, coarsely reticulate, granular and stripe2perforated. p resent study p rovides the main ecological factors, including geographical position (31 31 32 37 N, 116 40 117 52 E), altitude (70 20 m), annual p recip itation (900 1 000 mm ) and annual accumulated temperature of 10 (4 500 5 300 ) for the distribution area.
