Ciminalis clusii

Gentiana clusii (sometimes called "Clusius' gentian") is a large-flowered, short-stemmed gentian, native to Europe.

Gentiana clusii is named after Charles de l'Écluse (Carolus Clusius), one of the earliest botanists to study the alpine flora.

This species is very similar to Gentiana acaulis. The two species differ in the presence (G. acaulis) or absence (Gentiana clusii) of green stripes inside the corolla, by the shape of the corners between the petals (pointed in Gentiana clusii, more rounded in G. acaulis), but mostly in their ecology, with Gentiana clusiii preferring limestone areas, and G. acaulis being found over silicaceous rocks.

Gentiana clusii (like G. acaulis) is found in the Pyrenees, Alps, Apennines, Jura, Black Forest and the Carpathians.
