Rogério LupoFeather pen and ink cross hatching is a technique that has fallen into disuse today among artists of science illustrations. The illustration above won first prize in the 2013 Margaret Flockton Award for Excellence in Scientific Botanical Illustration international competition offered by the Royal Botanic Garden of Sydney, Australia. Biologist and illustrator Rogério Lupo drew this example of the species Vellozia perdicipes found in the Brazilian state of Minas Gerais to be included in the scientific article to be published by Renato de Mello-Silva from the Botany Department of the Biosciences Institute of the University of São Paulo.
