Conference paper


Zinnia (Compositae-tribe Heliantheae) is comprised of approximately 17 species native to the New World (Torres 1963). Two annual species, Z. angustifolia HBK (formerly Z. linearis Benth.) and Z. elegans Jacq., have long been in cultivation as ornamentals. The two species are distinct, both morphologically and cytologically, with n=11 or 12 for Z. angustifolia and n=12 for Z. elegans (Torres 1963; Terry-Lewandowski et al. 1984).
