Campanula alpestris, the alpine bellflower, is a species of flowering plant in the family Campanulaceae. It is native to the southwestern European Alps. The generic name (Campanula) comes from the shape of a bell flower; in particular, the word comes from Latin and means: small bell. From the records it shows that the first to use the botanical name of "Bellflower" was the Belgian naturalist Rembert Dodoens, who lived between 1517 and 1585. This name was still in use for some time, although modified, in many European languages. In fact, in these plants they were archaic French "Campanelles"

They are closely related to Cyperus species and sometimes treated as part of a more broadly circumscribed Cyperus. The genus was named for the 17th century Danish botanist Peder Lauridsen Kylling. Species include: Kyllinga brevifolia Kyllinga coriacea Kyllinga erecta Kyllinga exigua Kyllinga

The genus was first described by Otto Friedrich Müller in 1773, and is among the most common types of algae found in freshwater habitats. It has a cosmopolitan distribution. Typical colonies of Gonium consist of 4 to 16 cells arranged in a flat plate. Gonium is capable of both asexual and sexual reproduction. Along with other algae such as Volvox, Eudorina and Chlamydomonas, it is a model organism for studying the origins and evolution of multicellularity.
