[Objective]To observe the morphological characteristics of floral organs and leaf epidermis of F.suspensa,so as to provide basic information for introduction,cultivation and taxonomy study of fine varieties.[Method]The pollen,stigma,style,upper and lower leaf epidermis of F.suspensa respectively adhered to the double faced adhesive tap of sample cup,observed,photographed and measured under scanning electron microscope(SEM).[Result]The pollen,whose extine surface is coated with netlike ornamentations and 3-colporate,is prolate in shape.Stigma is dichotomous branching and dry stigma.The stomatal apparatuses of style epidermis are anomocytic type.The upper and lower leaf epidermises have different cuticle ornamentations,both of which are covered by glands and without trichomes.In addition,the stomatal apparatus are restricted to the lower epidermis.[Conclusion]This method is accurate,reliable.It could provide theoretical basis for introduction,cultivation and taxonomy study of fine varieties of F.suspensa.
