The Taxonomical Study Of Lespedeza Michx. In Inner Mongolia

In the present dissertation, summarized and reviewed senior's study of Lespedeza Michx., on the basis of this, studied plants of Lespedeza Michx. in inner Mongolia by means of polynology and cladistics taxology, discussed part of controversial species With menthod of and peroxidase isoenzyme pattern analysis.Through cladistics taxology study, evolutionary standard of Lespedeza Michx.: L.cyrtobotrya -L.bicolor -L.floribunda -L.inschanica -L.juncea -L.caraganae -L.tomentosa -L.daurica -L.potaninii.Through classical classification and polynology study shown that No.036 sample drawed up L.daurica (Laxm.) Schindl. var. multicaulis X.Hong var.nov.from Huhhot and No.021 Sample drawed up L.daurica (Laxm.) Schindl.var.halaqinica X.Hong var.nov. from Huhhot halaqin.Toward independence problem of L.potaninii Vassil.and L.inschanica (Maxim.) Schindl. Resultes of pollen feature, peroxidase isoenzyme pattern and numerical taxology all Supported species taxology status.Plants of Lespedeza Michx. have been recorded 7 species and 3 varieties in inner mongolia the author preliminaryly arranged the genus in the region,have 9 species, 4 varieties and 2 subspecies in which included 1 new recorded species, 1 new recorded subspecies and 2 new varieties.
