Hopes Smith's health is good. Intends to send copy of his Monandrian essay but busy correcting his "[Life and Pontificate of] Leo [the Tenth]" for second edition; defends the book against criticism in journals and "Critical Review" by stating the critics' ignorance of the period.

Sends draft of his paper [on 'Scitamineae']; if Smith agrees with principal points he can improve it with Smith's herbarium and library. Comments on a "sullen & ungracious" critique of his "[Life and Pontificate of] Leo [the Tenth]" in the "Edinburgh Review", pointing out its errors and his determination to respond to the "volumes of abuse". Pleased by Mr Reeve's "favourable opinion" of the book.

Responds to Smith's remarks on his Scitamineae paper, transcribes a new opening paragraph and makes other additions and corrections. Smith and himself should take strength against their attackers: [Richard] Salisbury's pamphlet ["Generic characters in the English Botany"] attacking Smith, and his own criticical reviewers in "Critical Review" and "Edinburgh Journal"; has written a paper against the latter. Thanks for numbers of "Exotic botany" but insists on purchasing the rest.

Thanks for Smith's and [Jonas] Dryander's remarks on his 'Scitamineae' paper; plans to add some notes before it is printed and other corrections based on fifteen Scitamineae plants sent by Lord Seaforth [Francis Humberston Mackenzie] from Barbados. Details some of the corrections he is making for second edition of "[Life and Pontificate of] Leo [the Tenth]".

Returns his revised paper on 'Scitamineae'; details some of the changes including rearrangement of genus 'Canna' after observations and thinks all the varieties marked in "Hortus Kewensis" are distinct species. Has been making improvements to his lands and buildings since start of the year. Encourages Smith to investigate difficult genus 'Amomum'. Has no interest in critical reviews of "Exotic botany" and encourages Smith to continue it, thinking that it will "answer much better in the result" than "English Botany".

Further remarks on his 'Scitamineae' paper; transcribes note to be added explaining Smith's discovery which has abolished 'Colebrookia', and discusses possibility of abolishing 'Globba'. Agrees that Smith should reprint the first sheet of "Flora Graeca", on basis that Smith is the editor, not the author, and to make other corrections. Has not seen issue of "Exotic botany" containing the plant named after him ['Roscoea'].

Thanks Smith for naming plant ['Roscoea'] after him in September issue of "Exotic botany"; discusses its claims to be a distinct genus based on his system. Unsure whether he should include the synoptical table in his 'Scitamineae' paper on account of it being "in the very teeth of Lin[naeu]s".

Ready to receive first parcel of herbarium Smith is preparing, and though [Liverpool Botanic] garden funds currently low is confident of success of a subscription for the herbarium. Has orders for several quatro copies of "Exotic botany"; asks [James] Sowerby to send direct rather than through booksellers. Suggests Sowerby and his son tour England to draw rare plants in private collections as research for "Exotic botany". Still considers Smith the "destined Editor of the works of Linnaeus"; discusses whether Smith should publish them by subscription. Proposes Lord [Edward Smith-]Stanley as FLS and requests certificate for his nomination.

Elected MP for Liverpool by a majority over both the other candidates.

Envelope, addressed to Smith, with note in red ink "Mr Roscoe's first Frank".

Encloses Lord [Edward Smith-]Stanley's FLS nomination certificate and asks Smith to find two signatories. Asks for copies of his last arrangement of genus 'Canna' and the first copy of of his paper on 'Scitamineae' plants; agrees that the genus needs investigation; wishes he had seen Smith's 'Canna glauca' in "Exotic botany" as Smith's figure differs entirely from 'Canna glauca' of "Hortus Elthamensis"; his knowledge of the two kinds of the genus, the nerved leaved kind, including 'Canna lutea', 'Coccinea', 'Canna latifolia', and the glaucos kind, including 'Cannacorus' of "Hortus Elthamensis", Smith's 'glauca', 'Maranta arundinacea' and 'Maranta sylvatica', which both agree with 'lutea' of [Nikolaus von] Jacquin; small ink sketch of detail of plant. Intends to distribute 'Monandrian' plants to friends with stoves.

[Parts of this letter appears to have been written some time before its dating, as Roscoe mentions being called to offer himself as a candidate in the election, which he won in early November].
