Kostly.. from my megare training in Botany (2.5 years).. i'm very interested in your article.. from both the studious and the playful perspectives..
can I suggest that you don't stop at what you can find online or immediatly around you.. but look further into the world of plants.. Most of the essential oils and spices we use in cooking come from a group of plants called the magnollid dicots (with the flagship bieng magnolia), which make up about 5% of plant species on the earth.. so theres a lot out there to explore! suggest you hit your library some weekend and research magnollids.. you might find something interesting that could be posted on here for the collective fun of the forum!
