Taxonomy and conservation of Cactaceae; botanical nomenclature; botany and history of cultivated plants; flora of Eastern Brazil; botanic gardens management.
Taxonomy of cultivated plants, especially those where living collections are essential for a proper understanding of characters and relationships. Principal focus over the last 35 years has been systematics of Cactaceae and their conservation (especially in connection with the Convention on Trade in Endangered Species and IUCN Red Listing), including some supervision of postgraduate students and refereeing of papers. Many other plant groups of importance for horticulture have also been included (>200 publications), especially other succulents and hardy woody plants, with a secondary emphasis placed on botanical nomenclature. At the Kew site, main responsibilities included management of c. 200 staff involved with the living collections in support of science, conservation, public education, horticultural training and amenity. Member of Kew Director’s team (until 2010) and Chair of Kew’s Overseas Fieldwork Committee (until 2011), with corporate oversight of expedition best practice in line with the Convention on Biological Diversity. Also, Kew contact for UNESCO World Heritage programme. Resigned post at RBG Kew upon appointment as Director, Singapore Botanic Gardens, 2011.
