The position about three kinds of lactuca brevirostris was discussed . the lanceolate - leaf lactuca brevirostris and the linear - leaf lactuca brevirostris were possibly two subspecies and two kinds of lanceolate - leaf lactuca brevirostris were possibly different species , lanceolate - leaf lactuca brevirostris 2 might be a variant or an external species 本研究還討論了三份野萵苣的地位,披針葉野萵苣與線葉野萵苣可能是不同的亞種;兩種披針葉野萵苣可能是不同的種,其中,披針葉野萵苣2可能是個變異種或外來種。
