Summary
Flora Dalmatica. Rob. de Visiani 1842-1852 - Phanerogamas. I have excluded all cultivated Plants. He seems carefully to have distinguished varieties from variations, & I think from polymorphism. I marked the vars. (a omitted)
N. B I suspect genera with 1 or 2 species present more varieties. Seldom, I observe all the species have vars. never in the even moderately sized genera. It is important that only few vary in the larger genera.
