British gardener and botanist, superintendent of Castleton Gardens, Jamaica (1873-1879) and of the botanic gardens in Georgetown, British Guiana, where he was also government botanist (1879-1902). Born in Plymouth, George Samuel Jenman trained at Kew (1871-1873) before travelling to Jamaica. After taking up his post in British Guiana (Guyana), which he held until his death, he was largely occupied in developing the colony's economic resources, carrying out many experiments with sugar cane. His principal botanical work was on the ferns of the West Indies, publishing numerous descriptions of new species in journals. He published in 1881 a Handlist of Jamaica Ferns and in 1898 commenced a series on the ferns of the British West Indies and Guiana in the Bulletin of the Royal Botanic Gardens, Trinidad. Unfortunately he did not see the series through to completion, dying prematurely at the age of 56. The series was carried on after his death, ending in 1909.
