Thanks Smith for specimens, including one from Linnaean collections. Requests specimens of 'Salix reticulata', 'Salix rubra', and others as he plans to study 'Salix' in the Fens this summer. Promises greater part of Smith's desiderata except for some plants from his "Flora [Cantabrigiensis]". Hopes he is a FLS. Asks if Smith's Cryptogamia is so complete as to not need his assistance.
