Abstract
The genus Potentilla sect. Aureae is represented in Latvia by four species: Potentilla incana P.Gaertn., B.Mey. & Scherb., P. crantzii (Crantz) Beck ex Fritsch, P. verna L. and P. subarenaria Borbás ex Zimmeter. There have been doubts about the occurrence of two species – P. verna and P. subarenaria. Research has shown that species are found in Latvia, but they are rare. P. crantzii has not been found in the last 20 years and is known only from herbarium records. The most common species of genus Potentilla sect. Aureae is P. incana. Our research shows that one of the most reliable and universally applicable characteristics is the type of leaf hairiness, as indicated in other studies. We primarily relied on submicroscopic characteristics, such as the type of leaf hairiness on both sides, as well as the hair types on the leaflets and on veins.
