Sending Smith specimens of 'Holosteum umbellatum'. Congratulates Smith on his publication ["Reliquiae rudbeckianae" (1789)] and praises the drawings. Saw that Smith intends to give up further investigation of English 'Carex caespitosa'; argues that the "great & little plants"are the same species and not varieties, caused by differences in soils and climates. Requests 'Alisma natans'. Mr Rigby, Mr Morgan, and two others are going to the glaciers; hints from Smith on what may be found would be appreciated. Encloses specimen for determination. Found 'Selinum palustre'.
