He arrived in Cape Town on 15 January 1834. Amongst his other observations during this time was that of the return of Comet Halley. However, in addition to his astronomical work, this voyage to a far corner of the British empire also gave Herschel an escape from the pressures under which he found himself in London, where he was one of the most sought-after of all British men of science. While in southern Africa, he engaged in a broad variety of scientific pursuits free from a sense of strong obligations to a larger scientific community. It was, he later recalled, probably the happiest time in his life." (from Wikipedia)

Jameson carried out botanical investigations at Baffin's Bay, in Ecuador, and in other South American countries; corresponded with Scottish and English botanists; sent plant specimens back to Great Britain (possibly elsewhere?); and published articles in a half dozen British and Scottish botanical journals. In 1864 he was appointed by the Ecuadorean government to write a flora of Ecuador.

Jackson in Origins and Meanings of Names of South African Plant Genera includes a genus spelled Lefeburea also in the Apiaceae honoring Louis F.H. LeFebure (c. 1754-1839). This individual, also listed as Louis F. Henri Lefebure with the same dates in the website of the Harvard University Herbarium, was a French botanist. And yet many online sources such as Flora of Zimbabwe, Flora of Mozambique, the POSA checklist, Tropicos and the Aluka website, and print sources such as Umbelliferae by C.C. Townsend all spell it Lefebvrea. I did find some reference on Tropicos to genus Lefeburea which it indicated had the correct name of Lefebvrea, so perhaps it was changed. I have also seen it spelled as Lefeburia, so this is very strange. I can't find any explanation for the change in spelling.

moorei (Crinum): Crinum moorei was described by 19th century botanist, Sir Joseph Dalton Hooker, while he was director of the Royal Botanical Gardens at Kew in London. According to Verdoorn (1961) his description was based on plants grown by Dr. David Moore (1838-1879), after whom he named it. Dr. Moore, director of the Glasnevin Botanical Gardens in Dublin, received the seed from a British soldier named Webb who collected it in KwaZulu-Natal during the 1860's. (PlantzAfrica) "David Moore's contribution to the Gardens, to its plant collections and to its reputation nationally and internationally is unsurpassed. His interests and abilities were wide ranging; he had studied the flora of Antrim and Derry, fungi, algae, lichens, bryophytes, ferns and flowering plants, before taking up his post at Glasnevin. While at Glasnevin he developed links with Botanic Gardens in Britain, in Europe and in Australia (his brother Charles became Director at Sydney). Moore used the great interest in plants that existed among the estate owners and owners of large gardens in Ireland to expand trial grounds for rare plants not expected to thrive at Glasnevin. The collections at Kilmacurragh, Headford and Fota, for example, attest to this. It was David Moore who first noted potato blight in Ireland at Glasnevin on 20th August 1845 and predicted that the impact on the potato crop would lead to famine in Ireland. He continued to investigate the cause of the blight and correctly identified it as a fungus but narrowly missed finding a remedy. David Moore was succeeded by his son Frederick, who was made Curator at the age of twenty-two. Some of the gardening establishment figures of the day were sceptical that such a young man would be up to the job. Frederick Moore soon justified his appointment and went on to establish Glasnevin as one of the great gardens of the world. In due course he was knighted for his services to horticulture."
