In base of:
• High content in exclusive Amaryllidaceae alkaloids • Biological and pharmacological activity of extracts and alkaloids previously isolated from this family species • Poor studied genus • Influence area: Mediterranean (easy to work) Selection of genus Narcissus
• 80-100 species • Narkào (=narcotic) penetrating smell of flowers from some species • Growing from lowlands to highlands • Flowering at the end of winter - spring
• Distribution South Europe (Iberian Peninsula and Italy) (also in North Africa and East Mediterranean)
