Observations on enclosed specimens: the true 'Cardamine parviflora' of Linnaeus; a specimen of the first moss he ever saw and which much puzzled him, a 'Gymostomum' like 'Davalli' but different. Has been arranging his Jungermannia and hopes to send specimens soon, along with 'Trichostomum rigidulum'. The specimen he sent as 'Dicranum ovale' identified. Observations on "difficult" moss 'G. browniana'.
