Description
Gagea sect. Stipitatae (Pascher) Davlianidze
All members of G. sect. Stipitatae were previously classified under G. sect. Platyspermum sensu lato (Pascher 1904, 1907, Stroh 1937, Uphof 1958 –1960). Gagea sect. Stipitatae, which comprises c. 60 species, is one of the largest sections in Gagea (along with G. sect. Gagea; Peterson et al. 2008). Peterson et al. (2008) included eight species from this section in their analyses. Since members of G. sect. Stipitatae were placed in four subclades in a clade that corresponds to clade D in Zarrei et al. (2009), this section must be merged with all other members of the clade D sensu Zarrei et al. (2009). Gagea chomutovae Pascher (1907: 372), G. gageoides and G. kunawurensis were included in the anatomical studies as members of G. sect. Stipitatae. These species exhibited type II and III pedicels and type IV basal leaves (Zarrei et al. 2010d). Gagea chomutovae, G. gageoides, G. kunawurensis and G. exilis of this section were included in a pollen morphological study by Zarrei & Zarre (2005); they exhibit four types of pollen that occur in other sections, so pollen characters do not support the monophyly of the section. Although there are several well-supported subclades composed of members of G. sect. Stipitatae, this section on its own is polyphyletic. For more information, see G. sect. Gagea and G. sect. Minimae below.
