Centaurea is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. In the western United States, yellow starthistles are an invasive species. Around the year 1850, seeds from the plant had arrived to the state of California. It is believed that those seeds came from South America.
Onopordum, or cottonthistle, is a genus of plants in the tribe Cardueae within the family Asteraceae. They are native to southern Europe, northern Africa, the Canary Islands, the Caucasus, and southwest and central Asia. They grow on disturbed land, roadsides, arable land and pastures.
Pierre Edmond Boissier was a Swiss prominent botanist, explorer and mathematician. He was the son of Jacques Boissier (1784-1857) and Caroline Butini (1786-1836), daughter of Pierre Butini (1759-1838) a well-known physician and naturalist from Geneva. With his sister, Valérie Boissier (1813-1894), he received a strict education with lessons delivered in Italian and Latin. Edmond's interest in natural history stemmed from holidays in the company of his mother and his grandfather, Pierre Butini at Valeyres-sous-Rances. His hikes in the Jura and the Alps laid the foundation of his zest for later exploration and adventure. He attended a course at the Academy of Geneva given by Augustin Pyramus de Candolle.

Centaurea tchihatcheffii is a species of flowering plant in the family Asteraceae. The flowers are most attractive as the pale or dark pinkish-red marginal florets take on an iridescent shimmer in the sun and wind, hence the vernacular name Yanardöner, meaning ‘iridescent flower’. It flowers from late April to mid-June and in cultivation even earlier, e.g., March in Istanbul. The peak flowering period is mid-May and in earlier years it was sold in some quantity by street florists in Ankara. It is mainly bee-, bug- and beetle-pollinated. Ants play an important role in seed dispersal and the fully ripe fat achenes are a delight for pigeons which settle down to feed in large flocks. The species is of taxonomic interest as it has some rather unusual and unique features not existing in any other Centaurea. For example, the marginal florets are funnel-shaped with crenate margins. The anther-tube is provided with glands at the tips of the appendages.
