  1. Based on the reseaching of lycoris leaf micro - morphology characters by sem scanning, light microscope viewing and using paraffin method in the article, we try to provide the proofs of experiment and the efffective characer indexes to discuss the system and evolution of the lycoris. we find these microscope characers through reseach are as follows : the arrangement type, density and the length of stoma ; the shape and length of the epidermal cells ; the ridge of epidermis ; the transverse shape of leaf ; the number of the vascular bundle ; the style of vessel arrangement of vascular bundle in the middle vein ; the layers of palisade tissue ; the ratio of the thicken of palisade tissue to that of spongy tissue ; the angle number of the middle leaf ; the type of ventilating cavity etc. these characters are different from those of species in lycoris, meanwhile these characters are similar to those of some species in lycoris. so these characters can be used as the character indexes for differentiating species and reseaching systematic evolution of lycoris ; we can divide lycoris into two subgenus by these characteristic indexes : the species of one subgenus are l. aurea ( l " her. ) herb, chinensis traub, l. caldweuii traub, l. anhuiensis y. hsu et q. j. fan, l. longituba y. hsu et q. j. fan ; the species of another subgenu s are l. houdyshelii traub, l. albiflora koidz.,

    研究結果表明：葉表皮的氣孔排列方式、長度、長寬比，脊的明顯與否，葉表皮上的顆粒紋飾的多少、大小，葉表皮細胞長度、長寬比、垂周壁形狀，上部葉柵欄組織細胞層數、葉的維管束數、葉中脈導管組成數目，氣腔類型，葉的脊部遠軸面的角數，葉緣的形狀等這些特徵在種間存在差異，同時，在有些種之間又有相似性；因此，這些特徵既可以作為區分種的證據，又是研究石蒜屬植物系統演化的性狀指標，根據這些性狀指標，可以將石蒜屬植物大致分為兩個亞屬：一是忽地笑、中國石蒜、短蕊石蒜、安徽石蒜、長筒石蒜，二是江蘇石蒜、乳白石蒜、石蒜、玫瑰石蒜、稻草石蒜；在兩個亞屬中其中有些種如忽地笑、長筒石蒜、中國石蒜的親緣關系則更近些。
