Section Primula
Type specimen: Radde s.n. June 1855. resides at Leningrad.
Distribution: Endemic to N and W Caucasus.
P. grandis was formerly thought to belong to a separate monotypic Genus, Sredinskya. Genetic analysis has proved that it belongs in the Genus Primula, Section Primula, despite having flowers like no other Primula species. See the paper "Phylogenetic analysis of Primula section Primula revelas rampant non-monophyly among morphologically distinct species" by Schmidt-Lebuhn et al.
