Abstract: The comparative anatomy of the leaves of 7 species in Polygonatum Mill . is studied in this paper. The results are as follows: (1) The raphide idioblasts are common in these species from Anhui province , but their number is different each other ; (2) No hairs on epidermis except lower epidermis of P. odoratum; ( 3) Stomatal apparatus only distribute in lower epidermis in random and single except P. ganlandeianense has both single and two or three get together ; (4) No differentiation of palisade tissue and the spongy tissue in the leaves except P. anhuiense and P. zanlanscianense have inconspicuous one . ( 5) Some stomatal apparatus characters such as size , type, distribution and shape of surface cells show more or less difference among the species . These characters provide experimental evidence for division of species and systematic evolution relationships of Polygonatum Mill .
