Bound notebook, with lecture notes and lists of plants, consisting of Latin names and their French equivalent, along with remarks in French (eg. '(dans le bois de Boulogne)' on fol. 24r). The first page of the manuscript is dated '1744 d. 9 Junii', when Bäck was staying in Paris. Linnaeus has written a few of his generic names in the margins.
The manuscript is probably derived from lectures followed in Paris:
fol. 4r: 'Lectio IIa'
fol. 7v: 'Lectio III. La classe des lubiacées'
fol. 11r: 'L. IIII'
fol. 16r: 'Lectio V'
fol. 19r: 'Lectio'
