    Rechinger f. (Fl. Iran. 165: 83. 1990) has cited the following three specimens, all from Chitral, under Tulipa biflora: Stainton 2667, Bowes Lyon 748 and 750 (BM). None of these specimens have filaments hairy at the base, hence these specimens are not Tulipa biflora. Stainton 2667 (BM) and Bowes Lyon 748 (BM) belong to Tulipa heterophylla and Bowes Lyon 750 (BM) belongs to Tulipa heteropetala.
