Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article considers endemic and subendemic species composition of Ketpen ridge flora. It has been educed that in the Ketpen ridge flora there are 46 endemic and subendemic species belonging to 28 genera and 17 families. Peculiarly, there are only 5 species belonging to 5 genera and 5 families: Endemic species of the Ketpen ridge: Fabaceae, Boraginaceae, Asteraceae, Zygophyllaceae and Brassicaceae. There are 41 species of subendemic species. The largest number of subendemic species contains the families of Asteraceae (15 species), Fabaceae (9 species), Liliaceae (4 species) and Brassicaceae (4 species). A wide range of species such as Astragalus (8 species), Galatella (4 species), Tulipa (4 species), Oxytropis (3 species), Saussurea (3 species), Taraxacum (2 species), Alchemilla (2 species), Achoriphragma (2 species) stand out among the genera. The analysis of life forms has showed that 58.2% of endemic and subendemic species belongs to the core polycarpous plants that are represented in the families of Fabaceae (11 species), Asteraceae (7 species), Brassicaceae (4 species), Lamiaceae (2 species) and a small percentage (10.8%) is represented by bulbous perennials and short-stemmed polycarpicles (6.5%).
