Thanks for letter and seeds of 'Limosella aquatica'. Recently received letter from [James] Sowerby containing a statement of his fasciculus [presumably Don's "Herbarium Britannicum" (1804-1812)], the first he has received since publishing the first 5 years ago; in "consequence of his negligence" he has brought "very considerable expense" and will be forced to give it up after printing seventh and eighth numbers. If Sowerby was the sole publisher of "English botany" he would not send any further plants, but encloses 4 of his recent discoveries for Smith's account.
Numbered observations on enclosed specimens: 1. 'Hypericum barbatum' or 'H. elegans'; 2. unknown species of 'Lamium', like 'L. amplexicaule', suggests 'L. intermedium'; 3. possible 'Juncus fasciculata'; new species of 'Equisetum'. Had intended to send them to be published in "Linnean Transactions". Identified one of the grasses he sent Smith last year as 'Agrostis arumdinacea', and has possibly found 'Bromus triflorus'.
