Son domaine de travail s'étendait à diverses régions d'Amérique latine, d'Afrique et d'Asie. Il fut non seulement un des membres fondateurs de l'Association de biologie tropicale, mais a également été membre de la Société linnéenne de Londres, de l'Association américaine pour l'avancement des sciences, et associé honoraire de la Société botanique du Brésil. Malgré des problèmes de santé, il entreprit l'organisation du premier symposium international sur la « systématique et l'évolution des graminées » qui s'est tenu à l'Institut Smithsonian en [2].
