John Horne FLS (1835–1905) was a Scottish botanist. He served as director of the Botanic Gardens of Pamplemousses, Mauritius.
The Sapindaceae genus Hornea is named after Horne.[1] [2]
Horne was born in Lethendy, Perthshire, Scotland. He worked at Kew in 1859 - 1860 and at the Botanic Gardens in Mauritius 1861 - 1891, serving as Director from 1877 onward.
He collected plants in Mauritius and the Seychelles.
Upon his transfer to Fiji, Arthur Gordon hand-picked a retinue of officials to accompany him, including Horne, who moved to Fiji a year after Gordon, in 1876.
Horne died in Jersey in the Channel Islands on 16 April 1905.
