英文摘要: This paper deals with morphology, karyotype, allozyme and Introduction and Cultivation of Typhonium Schott from Yunnan. 1. The morphology Morphologic characteristics of each species studied were described in details after carefully checking the specimens and well investigating the wild and cultivated plants. A new species-Typhonium jinpingense Z.L.Wang,H.Li et F.H.Bian was reported here for the first time based on the above studies. 2. The analysis of karyotypes Karyotypes of seven species in the genus Typhonium were analyzed. The chromosome numbers of two species were counted. The karyotypes of metaphase chromosomes in somatic cells were listed as follows: (l)T. giganteum Engl. 2n=4x=52=44m+7sm+lst (2)71 flagelliforme (Lodd.)Blume 2n=3x=24=3m+9sm(4SAT) +12st (3)71 calcicolum C.Y.Wu ex H.Li et al 2n=4x=52=23m(5SAT)+21sm +8st (4)T. Wwwe/Nicolson&Sivadasan2n=4x=52=40m (1SAT) +12sm(3SAT) (5)7*. trilobatum (L.)Schott2n=2x=18=12m+4sm(2SAT)+2st T. roxburgii Schott 2n=2x =18=10m(2SAT)+8sm T. jinpingense 2n=2x=10=2m+6sm+2st (8)7. omeiense H.Li 2n=26 (9)7! kunmingense H.Li 2n=52 The chromosome numbers of three species T. flagelliforme(2n=24), T. roxburgii(2n=\S), T. jinpingense(2n=10) were reported for the first time. In addition, chromosomal variation of species in the genus Typhonium and its probable oringinal basic number were discussed. The chromosomal ploidy and variability of structure and karyotypic characteristic of chromosomes between species were studied. These can offer dependable theoretical basis for hybridizing successfully and analyzing of allozyme. 3. Analysis of allozyme The genetic analysis was done by six enzymes for the first time. The result confirmed that T. flagelliforme(fcom Yunnan)was triploid. Tree diagram was drawn using Biosys-2 for cluster analysis of genetic similarity and distance. So genetic similarity of six species in Typhonium was defined. But the result was a little different from the results acquired by other methods. At the same time, the relationship between Typhonium, Sauromatum Schott and Pinellia Tenore was clarified. Namely Typhonium is more further from Pinellia than Sauromatum. 4. Studies on plant introduction The phenology, living environment and growing conditions were observed and analyzed. In addition, geographic distribution and wild growing conditions were also analyzed. The suitable cultivated condition was also analyzed. The sexual reproduction and pollination of T. calcicolum was observed. Vegetative propagation on some species was also studied and satisfied resultswere achieved. 5. Summary of medicinal value One of the important research values in Typhonium is its high medicinal value. Then medicinal value and geographic distribution of five species in China were summarized.
