Brand new Friends of Charles Darwin member Germán Roitman, FCD, of Pilar, Argentina writes:
Dear Richard:
As a botanist I have a great admiration about Charles Darwin, and in 2008 I had the chance to publish and dedicate a new species of Iridaceae to Charles Darwin in commemoration of his 200th birth anniversary. Herbertia darwinii is a bulb plant that grow in grasslands in Argentina, Uruguay and Brazil.
Please find enclose a picture and a drawing of the plant, and the paper.
Its a pleasure for me to join the Friends of Charles Darwin webpage.
Best regards
Germán Roitman
I have to say, Herbertia darwinii is a stunning flower:
