052187A4EF291E2FFF22FA86FE8647BC.taxon	discussion	Taxonomic notes: — Wang (1981) pointed out that the length of calyx and marginal glochids of nutlet were essential to identify L. balchaschensis and L. deserticola. Based on thorough examination of specimens and field investigations, we found that the length of marginal glochids was not useful to clarify these two species, because this character was quite variable within population for L. balchaschensis. We also carefully observed the nutlet morphology of L. deserticola, and the nutlets of this species were heteromorphic (Fig. 2). Based on morphological comparisons, we considered that the features of nutlet margins may be more critical than the length of marginal glochids for identification of L. balchaschensis and L. deserticola.	en	Liu, Dan-Hui, He, Yi, Liu, Quan-Ru (2022): Lappula deserticola var. longicalyx-a new synonym of Lappula balchaschensis (Boraginaceae).
