Studies on Species of the Ranunculus auricomus Complex in the Flora of Latvia: Ranunculus cassubicus Group

Traditionally, all authors in Latvia summarise all agamic species of the Ranunculus auricomus complex under three species, auricomus L., R. fallax (Wimm. et Grab) Sloboda, and R. cassubicus L. However, there are many compelling studies showing that the R. auricomus complex is a large assembly of apomictic microspecies. In this article, 17 species of the R. cassubicus group in Latvia are presented: R. angustior (Markl.) Ericss. R. cajanderi (Fagerstr.) Ericss., R. cassubicus L. s.str., R. circinatifrons (Markl.) Ericss., R. elatior (Fries.) Ericss., R. hannae Jasiew., R. imitans (Markl.) Ericss., R. inopinus (Markl.) Ericss., R. karelicus (Markl.) Ericss., R. macrantherus (Markl.) Ericss., R. niepolomicensis Jasiew., R. pawlowskii Jasiew., R. prorsidens (Markl.) Ericss., R. scalaridens (Markl.) Ericss., R. serratifrons (Markl.) Ericss., R. svirensis (Markl.) Ericss., and R. tranzschelii (Fagerstr.) Ericss.
