Nancy,
Jay is right, in Brazil the Cogniaux's work is more well known than Reichenbach fil. Cogniaux was a great collaborator of Von Martius' masterpiece "Flora Brasiliensis" (freely available at
Flora brasiliensis, CRIA ). Reichenbach was invited to work but, due his notorious vanity, he refused after he knew he would not be the head!
Congrats for your 15 minutes of fame!
