In 1722 Bernard became assistant demonstrator of plants there. He kept this post for the rest of his life. In 1759 Bernard was asked to develop a botanical garden at the Petit Trianon (Versailles).

In return, Adriaan sent a considerable number of materials from the Leiden garden to Von Haller and was one of the main suppliers of new species for Von Haller’s garden ( Gradstein & Schwerdtfeger 2009: 14–16).

In 1739 and 1741 he led botanical expeditions in Russia. When in 1742 his position at the medicinal garden was discontinued, Gerber went to Finland as a physician in the Russian army. 15 Six letters of A. van Royen to T. Gerber are in the Waller Manuscript Collection, Uppsala University Library (Ms benl-00618-00623).

In 1717–1720 he visited the Lower Volga Region as well as the northern and northwestern shores of the Caspian Sea ( Sokoloff et al. 2002: 133). One of his letters (Moscow, 31 August 1731) to A. van Royen is in the Waller Manuscript Collection , Uppsala University Library ( Ms benl-00617) .

Spain

– Rouveroij (?–?) (two specimens) — Corresponded also with Boerhaave ( Wesseling 2019: 241), but nothing else is known about him.

Sweden

– Eric Gustaf Lidbeck (1724–1803) (one specimen) — Curator of the botanical garden in Lund (Stafleu & Cowan 1981, Vol. 3: 10). Lidbeck met Adriaan van Royen in Leiden when he visited The Netherlands in 1752 .17 Three letters of A. van Royen (1753–1755) are in Lidbeck’s correspondence. 18

– Carl Linnaeus (1707–1778) (three specimens) — In Linnaeus’s correspondence there is one letter of Linnaeus to A. van Royen and 25 letters by A. van Royen to Linnaeus, all written between 1737 and 1753 (https://www.alvin-portal. org/, last accessed 24 April 2022).

Switzerland

– Johannes Gessner (three specimens) — Corresponded with A. van Royen ( Boscani Leoni 2017: 72) and also with J.F. Gronovius ( Boschung 1996: 76).

The Netherlands

– Herman Boerhaave (c. 90 specimens; see Offerhaus et al. 2022) — Adriaan van Royen’s teacher and predecessor.

– Johannes Burman — Professor of botany in Amsterdam from 1731. Johannes obtained his doctorate on 12 March 1728. In honour of this occasion A. van Royen wrote a Latin verse for his friend that was added to Burman’s dissertation ( Burman 1728). Johannes did the same for Adriaan who promoted on 23 March and his verse is printed in Adriaan’s dissertation ( A. van Royen 1728 ). Despite their friendship, the number of herbarium specimens that Johannes sent directly to Adriaan seems very small. By far the majority of the specimens attributed to Burman in the IDC guide ( Thijsse 1998 –2002, Thijsse & Veldkamp 2003) are probably specimens from the herbarium of Albinus (see Appendix 3). 19 Several letters of A. van Royen to J. Burman are in the Leiden University Library (Special collections, BPL 885).

17 Letter by E.G. Lidbeck (19 August 1752) to Linnaeus (Linnaean correspondence L1463).

18 https://www.alvin-portal.org/ (last accessed 24 April 2022).

– Johannes de Gorter (1689–1762) (one specimen) — Professor of medicine at Harderwijk University. Promotor at Linnaeus’s doctorate in Harderwijk .

– Johan Frederik Gronovius — Author of Flora Virginica. Adriaan van Royen undoubtedly received herbarium specimens directly from Gronovius. However, identifying particular Gronovius’ specimens as belonging to one of the Van Royens is problematic, because Meerburg also had a set of Gronovius material (see Handwritings below).
