Kurzfassung:
Lappula sinaica was recently transferred to the monotypic genus Pseudolappula based on phylogenetic studies, while the related species, L. occultata , has remained in the genus Lappula . In this study, morphological, molecular, and palynological evidence supports that L. occultata should be transferred to the genus Pseudolappula . Both L. occultata and P. sinaica share a combination of nutlets features that distinguish them from Lappula : a longer adaxial keel and a linear attachment scar. Phylogenetic analysis based on ITS and trnL-F strongly supports L. occultata as the sister taxon of P. sinaica . In addition, pollen grains of these two species are 3-syncolporate with 3 alternating pseudocolpi, which is significantly different from the grains of Lappula taxa. Based on the above evidence, the new combination Pseudolappula occultata is proposed.
