His suggestion that L. chinensis is a tetraploid is not true as we now know from study of its Karyotype and L. squamigera is a triploid. Actual hybridization work does not include L. chinensis is the parentage of L. squamigera." It was not Sam Caldwell who suggested that the Glenn Dale yellow Lycoris might be tetraploid; it was Jim McKenney. Reports that Lycoris chinensis is diploid are interesting but irrelevant unless the Glenn Dale yellow lycoris was used to determine such chromosome counts. Furthermore, Jim McKenney made no assertions about the parentage of Lycoris squamigera in that posting.
