Pleased to see Macleay's handwriting "after so long an interval". Concerned to hear of the death of [Olof] Swartz, one of his "most constant correspondents", with death of [Carlo Antonio] Bellardi leaves 4 FMLS vacancies; nominates [Augustin] de Candolle and [José Antonio] Pavon, in spite of the latter's financial situation, Lamarck, and [Franz Karl] Mertens. Considered [Kurt] Sprengel. [Georg] Meyer dedicated his "pompous" "Flora Essequeboensis" to the Linnean Society and is ambitious of joining, but must not be chosen for FMLS yet.
Apologises for delay in remarking on plants sent by Swainson; finishing his part of Rees's "Cyclopedia". "Little hairy fern with simple fronds" found Rio Janeiro agrees in size and shape with 'Blechnum Lanceola' of Swartz in Stockholm Transns. for 1817. p. 71. t. 3. f. 2; observations. Grass marked 'Digitaria of Persoon?' is 'Paspalum conjugatum' Willd. Sp. M., also 'P. dissectum' of Linnaeus' Syst. Nat. ed. 12. v. 2. Dark-cold grass from "deep forests at Pernambuco" another 'Paspalum', species unknown. 'Cyperus', 'culm triangular, bogs at Pernambuco' unknown. "Very rare" grass, from "sandy table lands in the interior of Pernambuco", close to 'Agrostis radiata' of Linnaeus. 'Cassia' "in dry sandy tracts" unknown. A new 'Lythrum', near 'racemosum' but distinct. An 'Eriocaulon fasciculatum' of Lamarck & Willdenow, or very near it. Their plant appears to want the many awlshaped leaves of the common calyx, or involucrum. A 'Campanula' appears to be 'C. minor ['minima'] africana, erini facie &c', Hermann Leigd. Bot. 108. t. 111, erroneously cited by Linnaeus for his 'C. erinoides'; has this plant from Sierra Leone. Does not have his 'Hyptis' under that genus, does not seem to be any of Willdenow's.
