Berthold Carl Seemann (25 February 1825, in Hanover, Germany - 10 October 1871, in Nicaragua, Central America), was a German botanist. He travelled widely and collected and described plants from the Pacific and South America.

In 1844 he travelled to the United Kingdom to studied botany at the Royal Botanic Gardens, Kew. On the recommendation of Sir W.J. Hooker, he was appointed naturalist on the voyage of exploration of the American west coast and Pacific by Henry Kellett on HMS Herald, 1847-1851, along with the naturalists Thomas Edmondston, and John Goodridge. The expedition returned via Hawaii, Hong Kong and the East Indies, calling at the Cape in March 1851. Here he met up with his old acquaintance Zeyher, and with Baur and Juritz they climbed Table Mountain on 13 March 1851, Ecklon being unwell and unable to accompany them. On 16 March Zeyher introduced him to Bowie at Wynberg. He left the Cape on 27 March and was back in England on 6 June 1851. The botanical results of the voyage were published as Botany of the Voyage of HMS Herald and he was awarded a Ph.D. by the University of G÷ttingen in 1853.

In 1859 he travelled to Fiji and published a botanical catalogue of the flora of the islands, entitled Flora Vitiensis. It was the foundation for Flora Vitiensis Nova, published by Albert C. Smith from 1979 to 1991. In the 1860s he visited South America, travelling in Venezuela in 1864 and Nicaragua from 1866 to 1867. He later managed a sugar estate in Panama and the Javali gold mine in Nicaragua, where he finally succumbed to malaria.--Wikipedia, retrieved August 2020.

"Walter Hood Fitch was born in Glasgow in 1817. By the age of 13 he was employed as an apprentice pattern drawer at a mill. He took to botanical illustration following a meeting with William Jackson Hooker, who was so impressed by young Fitch's artistic talents that he bought him out of his apprenticeship. Fitch went on to be an exceptionally prolific botanical illustrator, with over 12,000 of his images seeing publication."--Kew website, retrieved September 2020.
