Chrysanthemum perunianum (Dodoens 1568)
Chrysanth. perunianum (Dodoens 1569)
Chrysanthemum peruvianum (Dodoens 1583)
It comes from the same wood engraving. It represents a cultivated type with only one big head. Leaves are drawn as alternate, although they are in fact opposite decussate.
During centuries, sunflower was grown as an ornamental. Targioni-Tozzetti mentions it as an ornamental, and Candolle omits it because he did not deal with ornamentals.
Read Targioni-Tozzetti (1853), Gray & Trumbull (1883) and Sturtevant (1919) articles.
