The Pamplin Papers consists of letters addressed to William Pamplin and a few other individuals, along with some miscellaneous items dating from 1806-1886. There are well over 200 correspondents, nearly all of them eminent botanists of the day, British and foreign. The letters are mostly written in English with a number in French and German and a many deal only with business details. However, some are of great historical interest because they throw light on botanical activities in a period when the exploration of the flora of little known plants of the world was one of the main interests of botanists. Amongst the correspondents are Charles Darwin, Sir William Jackson Hooker and Friedrich Martin Jozef Welwitsch.
Included also are the working papers of Mr Tully, such as the queries he received and his index cards which could be of great use to the researcher. These indices contain the names of botanists and of the plants mentioned within the correspondence.
