Notes.

Tulipa ostrowskiana was described in 1884 by E. L. Regel from collections near Verny (Almaty). This species was first collected in 1879 by A. E. Regel and A. M. Fetisov (the chief gardener of Pishpek (Bishkek) in charge of the Treasury Garden in Verny) ( Ivashchenko and Belyalov 2019). Zonneveld (2009) suggested that T. ostrowskiana may be an allotetraploid originating from T. kolpakowskiana and T. lemmersii based on genome size. Spontaneous hybrids of T. ostrowskiana and T. kolpakowskiana with intermediate flower coloration and habit traits are known in nature ( Vvedensky 1935; Ivashchenko and Belyalov 2019).
