He works at Kirstenbosch National Botanical Garden in Cape Town, one of the world's great botanical gardens and an important center for research on the African flora. Although he has studied the anatomy, embryology and seed development of plants in diverse families, including the Fabaceae, Proteaceae and Stilbaceae, he has focused his research more recently on the Iridaceae, collaborating on various research projects with Peter Goldblatt. Together they have investigated the evolution and pollination biology of the African genus Lapeirousia and the systematics, pollination systems and evolution of Gladiolus in southern Africa. John and Peter have coauthored several books, including Gladiolus in Southern Africa and various wildflower guides to the southern African flora, the most recent of which was Wildflowers of the Fairest Cape (Redroof Design and Timber Press, 2000). John is also an accomplished botanical artist and photographer; his drawings have been published in numerous books and scientific journals.
