This book is a record of some 2,700 people who have collected herbarium specimens in Uganda, Kenya and Tanzania, designed as a supplement to the now complete Flora of Tropical East Africa. The profiles give an indication of careers and interests, the places where the plants have been collected and herbaria in which the specimens are located. A timeline and a synopsis give an idea of professions and the changes through the eras since the first recorded herbarium specimens were collected in 1781. Accompanied with line illustrations and black and white photographs throughout.
