I found many discordant references on the web (and even on books) about
Osteospermum and Dimorphotheca ?

What is the difference ?
What is the key that make us distinguish between the two genus ?

Mida
(Italy)

From the PLANTS national database for US plants http://plants.usda.gov/

CATR18 Castalis tragus (Ait.) Norl.
DIAU3
Dimorphotheca aurantiaca DC., non Horton



DIPL4 Dimorphotheca pluvialis (L.) Moench
DIAN9
Dimorphotheca annua Less.



DISI4 Dimorphotheca sinuata DC.



OSEC Osteospermum ecklonis (DC.) Norl.
DIEC2
Dimorphotheca ecklonis DC.





So we have three genera to deal with in this question! Beyond this I can't
help.
