Abstract:
The main original plant of the traditional Chinese drug Mianbeixian has been consi-
dered as Dioscorea septemloba Thunb. for a long time. Based on morphological, light micros-
copical, scanning electron microscopical, chromatographical and ultra-violet spectroscopical exa-
minations and in comparison with the Japanese material, the Chinese one is proposed as a new-
species-Dioscorea spongiosa.
