Nomenclatural note. Veronica macrostemon is a species endemic to the Altai and adjacent Sayan Mountains.The type collection is from alpine scree near the river Tschuja. Kosachev (2011) lectotypified the species with material from LE but failed to check for other original material outside LE. I, therefore, add to the lectotypification here. A number of specimens of Bunge exist that are not explicitly mentioned to be collected near river Tschuja NY[NY00130766, JE00003110, M0188520) and are, thus, not considered isolectotypes. The specimen in B that was mentioned by Stroh (1942) is likely destroyed. Interestingly, no original material by Bunge for the related V. densiflora , also lectotypified by Kosachev (2011), was found in P.
