Preparing 'Salix' for the "The gardener's and botanist's dictionary", asks whether Smith agrees with [Georg Franz] Hoffmann's arrangement of the genus and for information on 'Salix hermaphroditica' and 'Salix pentandra'. Asks after various publications including: second volume of [Antonio José] Cavanilles' "Icones"; whether there are further [Jacques-Julien La] Billardiére fasciculi; whether [Peter Simon] Pallas published more of "Flora Rossica"; and if there will be anything further from [Charles Louis] L'Héritier [de Brutelle].
