Jean-Théodore Descourtilz (1796-1855) was a well-known ornithologist who produced beautiful illustrated books on Brazilian birds. Less-known is an unpublished manuscript with water-colours of Brazilian orchids, which was acquired by the wealthy French Baron Delessert, who send it on loan to John Lindley. Lindley described dozens of new orchid species based on Descourtilz’ illustrations and used several of them as models for his beautiful publication Sertum Orchidaceum. Here we present a large selection of Descourtilz’ original illustrations of Brazilian orchids, including all the drawings that have been used by Lindley to typify his new taxa based on Descourtilz’ exploration.

His in Brazil, in the province of St.Paul’s — Descourtilz — illustrations in the Flore des Antilles must have been (v. ic. pict. in bibl. De Lessert)1. This somewhat cryptic based either on herbarium specimens or perhaps on annotation can only be understood as that Lindley found sketches made in the field by his father. Another an illustration by Descourtilz of the plant now described possibility is that he never produced the illustrations as a new species. This is corroborated after further of the Flore des Antilles, and that they came from studying Lindley’s descriptions of other new Brazilian the hand of another artist, perhaps his father himself. species, when we read, in his description of Ionopsis Either way, the two sets of illustrations have little in paniculata: …a very remarkable species, with which common.
