Johannes's Profile

I am a biochemist from education. Developped an interest in Botany some 40 years ago, especially in the taxonomy and morphology of the plant family Solanaceae. Started to write a book (more than 2000 species and varieties) with the title "Synopsis of the plant family Solanaceae" some three years ago and estimate to finalize this in another three years. In the mean time I am trying to collect copyright free pictures. Of course I will make reference to the letigimate owner.
