One of the aims of the institute was to help promote botany as a means for mental culture and relaxation, an idea that was not shared by Henry Groves, a trustee for the institute. Hume objected to advertisement and refused to have any public ceremony to open the institute. The first curator was W.H. Griffin and Hume endowed the institute with £10,000. Frederick Townsend, F.L.S., an eminent botanist, who died in 1905, had left instructions that his herbarium and collection was to be given to the institute, which was then only being contemplated. Hume left £15,000 in his will for the maintenance of the botanical institute.
