Tulipa kolbintsevii Zonn.

Tulipa kolbintsevii Zonn., Pl. Syst. Evol. 298: 1294 (2012). Fig. 27 Type. Kazakhstan • Grown in the Netherlands from material collected at Dzjungarian Ala-Tau, Taskora Valley, cult. J. J. de Groot (holotype L 0821329!). General distribution. Endemic to Kazakhstan (Kubentayev et al. 2024). Distribution in Kazakhstan and habitat. Dzungarian Alatau. This species grows among shrubs at an altitude of 650 m a. s. l. Conservation status. Tulipa kolbintsevii is an endangered species at the global level (IUCN 2024). Phenology. Flowering in March – June; fruiting in May – June. Notes. Tulipa kolbintsevii was described from the cultural collection of J. J. de Groot in the Netherlands, collected from Taskora Valley, 650 m from Dzjungarian Ala-Tau, Kazakhstan (Zonneveld and de Groot 2012). The main difference between T. kolbintsevii and other Tulipa species in the section Biflores is that the sepals have a pilose margin at the base rather than a pilose band. This species was named in honor of V. Kolbintsev, who guided the expedition leading to discovery (Zonneveld and de Groot 2012). Tulipa kolbintsevii is diploid, with a 48.0 pg genome size, smaller than that of other species in T. sect. Biflores, ranging from 51.5 to 76.3 pg (Zonneveld 2009). The distribution of this species is poorly studied, and known from only two localities, including “ locus classicus ”.
