We take a look at the varied career of Everard Im Thurn through his correspondence with the Directors of Kew, and find out about his exploration of the 'lost world' of Mount Roraima in British Guiana.
Before we started contributing to this blog, our team published some interesting finds from the Directors' Correspondence in Kew's staff magazine, VISTA. We came across these stories recently and thought they were deserving of a wider audience.
"Will no one explore Roraima and bring us back the tidings which it has been waiting these thousands of years to give us?" The Spectator, April 1877
Early explorers in Latin America spoke of mysterious mountains towering above the jungles and reaching into the clouds. These dramatic sandstone mesas are called tepuis and are some of the world’s oldest rock formations. Mount Roraima is the tallest such tepui, lying where the borders of Guyana (formerly British Guiana), Brazil, and Venezuela meet. Its flat summit reaches over 9,000 feet with high cliffs dramatically maintaining its isolation.
Tantalizing tales of the attempted exploration of this mountain and the failure of anyone to reach its summit fuelled Victorian speculation as to what might lie at the top of the ancient plateau, and inspired Kew's then Director, Sir Joseph Hooker, to use his influence to support an expedition. In 1884 Everard Im Thurn, an author, explorer, botanist and anthropologist of Swiss extraction and the Magistrate in Pomeroon at the time, led a team that became the first to reach Roraima's summit and their success paved the way for further scientific explorations.

The Directors' Correspondence collection contains letters regarding the details of Im Thurn’s expedition and also letters from his friends and colleagues, W.H. Campbell and G.S. Jenman. From plant specimens sent back to England, staff at Kew identified over 50 species new to science such as Bonnetia roraimae.

Reports from Early Victorian expeditions to Roraima are thought to have inspired Sir Arthur Conan Doyle’s imperial adventure yarn The Lost World (1912) based around an expedition to a plateau in Venezuela where prehistoric animals had survived. On his return from the summit of Roraima, Im Thurn authored several works related to his travels. Everard pursued a career as a colonial administrator, culminating in a position as Governor of Ceylon (Sri Lanka). He maintained a high profile in British scientific circles throughout his life, was a prolific contributor to popular and scientific journals, and was President of the Royal Anthropological Institute.
Im Thurn’s correspondence with the Directors of Kew spans his long career and offers an insight into the kind of botanical material he exchanged, the gifts he sent to the museum at Kew, his botanical interests, and his thoughts on matters as varied as publishing and the division of country boundaries. His letters demonstrate a great love for Guyana and even in 1887 he discusses the rapid rate at which the unexplored interior of British Guiana is disappearing and his fears that the native peoples could soon vanish. Whilst in London in 1900 he wrote to then director Thiselton-Dyer:
"I walked home tonight through Piccadilly and had my attention called by my companion to the shops – but I was quite homesick for my bush paths and longed for the chance of meeting either a crapaud [frog] or a jaguar or something interesting." Directors' Correspondence 204/366 (RBG Kew)
Im Thurn was also a keen amateur photographer and sent several photographs to Kew, including this photograph of Catasetums, a type of Orchid, growing in his Guyana garden.

Im Thurn’s varied and exciting career is an important part of the Cross-cultural Histories of Tropical Botany in Latin America project being under taken at Kew by Sara Albuquerque. You can search Kew's digitised Im Thurn correspondence via the JSTOR Plant Science website.

About the Tropical Nursery
The main functions of the Nursery are to:
- Form a back-up collection of tender tropical plants used to support science, display and education within the gardens. We supply plants for use in displays in the Main Kew conservatries, for festivals and events organised by the Foundation and the Directorate.
- Supply plants for education purposes to the Schools & Families department.
- Act as main propagation facility for the Princess of Wales Conservatory, Palm House and Temperate House as well as supporting the exchange of plants between Kew and other institutions and collections.
- Provide direct education in nursery techniques and the cultivation of tropical plants for the Kew Diploma course, Apprentice and Trainee programme, Internship and work experience programmes and visiting staff from other UK and overseas institutions.
- Support conservation by working with the UKOTs team undertaking propagation and cultivation protocols on targeted endangered species.
