Sending 'Juncus' specimens from his herbarium, delayed by his comparison with the specimens [James] Bicheno sent to Linnean Society accompanying his paper on subject; observations on species.

Wrote to Joseph Woods regarding 'Rosa systala' and his paper on 'Rosa' for "Linnean Transactions", transcribes part of Woods' reply. Woods explains an apparent confusion caused between 'Rosa systala' and [Nicaise Auguste] Desvaux's [(1784-1856) French botanist] 'Rosa stylosa', not having seen Desvaux's "Flore d'Anjou" at the time of his paper.

Discusses the genus 'Rubus': [James] Bicheno, [William] Borrer, and himself have examined Weihe's ["Rubi Germanici" (1822-1827)]; believes he has some of Weihe's specimens, which he offers to send to Smith for investigation.

Recently sent Smith specimens of 'Salix glauca' and four roses, not knowing which he referred to as not a variety of '[Rosa] arvensis'. Does not know Smith's 'R. subglobosa'; thinks others of [Joseph] Woods' [(1776-1864)] varieties may rank as species; thinks he should have united two more of Smith's list, the 'R. woodsii' with 'R. dumetorum', and 'R. canna' with 'R. sarmentacea'. He has found and cultivated 'R. collina'; observations.

Discusses work of himself, [William] Borrer, and [James] Bicheno on 'Rubus', observations on 'Rubus cordifolius' and 'Rubus rhamnifolius'; will send specimens to Smith, named on authority of Merten and Weihe. Also sending plant of 'Campanuta punctata'.

Account of discussion with [Joseph] Sabine on roses.

[Bicheno's letter:] proposed rearrangement of the genus 'Rubus'.

[Forster's note:] queries some of Bicheno's decisions.
