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 本研究还讨论了三份野莴苣的地位，披针叶野莴苣与线叶野莴苣可能是不同的亚种；两种披针叶野莴苣可能是不同的种，其中，披针叶野莴苣2可能是个变异种或外来种。
