Alick W Westrup was a founder member of the Hampshire and Isle of Wight Naturalists' Trust, now the Hampshire and Isle of Wight Wildlife Trust. For a number of years, until his sudden death in 1964, he had been working on a new 'Flora of Hampshire and Isle of Wight'.
His collection of plant specimens from Hampshire (vice-counties 11 and 12) and the Isle of Wight (vice-county 10), with a few from Dorset and further afield, was about one third completed at the time of his death. A W Westrup left his work to the Trust for the completion of the publication that he had started. The Westrup Herbarium was passed to Hampshire County Council for safe keeping and, in 1988, in accordance with conditions laid out by the Trust, transferred to the Hampshire County Council Museums Service.
Since being in the care of the Museums Service, the collection has been remounted where necessary and in many instances for the first time. The latter plants were stored in newspaper prior to further work being carried out by Westrup himself.
