Necker was not the first botanist to regard the Tournesol as 
the type of a distinct genus. A quarter of a century earlier 
Adanson had done this, as O. Kuntze has remarked (Rev. Gen. 
Pl. ii. p. 621), under the old French name Tournesol used by 
Magnol and latinised by Scopoli into Tournesolia, ‘welcher

wilkirlich in Chrozophora veraindert wurde.’ This, although a 
perfectly accurate statement, does not tell the whole story; 
agnol’s use of the name Tournesol was not published until 
after his death.
