Dated 24. Janrii 1781. Sent from Edinburgh (Great Britain) to Uppsala (Sweden). Written in Latin.

Celeberrimo Viro,
D[omi]no Professori Carolo a Linné,
S[alutem] pl[urimam] d[icit]
Jo[annes] Hope.

Epistola tua amica et urbana mihi gratissima fuit. Valetudo infirma & aliae curae, quo citius ad te responderem prohibebant. Dissertationes tamen plures medicas aliquot abhinc hebdomadas ad te cura D[omi]ni Dryander transmittendas curavi.

Quod Supplementum System[atis] Regni Veget[ationis] descriptione plantarum, quae producant Fabam St Ignatii, Ipecacuhannam veram officinarum, Balsam[um] Peruvian[um], Oleum Palmae, Anacardium Orientale, Santalum rubrum, Ebenum cubebas Lign. Rhodii &c. ditatum, edidisti, tibi gratulor. Propterea unusque Medicus tibi se devinctum sentiet & Zoologici quoque diligentiam tuam grati agnoscunt.

Gratias tibi ago ob semina urbaniter promissa; quae praecipue desidero, postea indicabo. Interim, ut ad me transmittendas curas plantas aliquot teneras vel surculos Sorbi vestrae hybridae, precor.

Effectus pollinis antherarum in mutanda specie insigne habuimus in horto Botanico exemplum.

1779 flos, farina urgidus, Papaveris oriental[is] in alium florem Papaver[is] Somniferi staminibus privatum insertus fuit, ibique retentus. Papaveris somniferi semina maturuere, haecque semina plantas produxerunt persimiles Papaveres. Orientalis nisi quod caules fere semper multiflori fuere.

Tanta tamen fuit similitudo, ut ne error quidam irrepserat. De experimento silebam, donec aestate elapsa repeteretur, quo quidem summa cura anno 1780 facto, similes & pergrata mutatio facta fuit & nunc sunt mihi aliquot plantae hybridae ex seminibus Papaver[is] Somniferi ortae Papaveris orientalis simillimae. Quod experimentum quosdam apud nos Philosophos incredulos titubare fecit.

Planta hybrida anni 1779 hac aestate floruit, sed semina haud maturavit.

Vale, Vir celeberrime, & me Ama!

Edinburgi
24 Jan[ua]rii 1781.

A Monsieur
Mons[ieu]r Charles a Linné

] as, for example, Faba St. Ignatius, Ipecacuhanna vera officinarum, and Balsamum Peruvianum.

Hope is grateful for seeds that Linnaeus the Younger has promised to send.

Species have been changed with the help of pollen; this took place in 1779 in the Botanical Garden of Edinburgh [Royal Botanic Garden EdinburghRoyal Botanic Garden Edinburgh,
Scottish. Founded in 1672 as a physic
garden to grow medicinal plants.
].

Hybrid plants originating from seeds of Papaver are discussed. An experiment with Papaver orientale and Papaver somniferum is mentioned.

Thus in 1779 a hybrid plant flowered, but yielded no seeds.
