Nomenclatural note. Another species collected by Bunge in the summer of 1826 from the river Tschuja is Veronica sessiliflora . The species status was doubted first by Elenevsky (1978) who suggested it to be a hybrid between V. porphyriana and V. pinnata, a hypothesis later confirmed by Kosachev et al. (2019) and Khan et al. (2024). The species was as the previous one lectotypified by Kosachev (2011) but again without mentioning other herbarium specimens.
