In Uzbekistan, T. sect. Lanatae is represented by seven species. The species are mainly distributed in the middle belt of Uzbekistan part of the Pamir-Alay Mountains. The taxa can be easily distinguished by biogeographic (southern part of Uzbekistan) and morphologic criteria (inner surface of bulb with profuse hairs and the same length of the tepals of the red-coloured perigone). The diagnostic key for species of the section is presented below.
