Romanus became good friends with Augustin Pyramus de Candolle, and the two would often send correspondences and exchange specimens. Romanus was personally thanked for his contributions in de Candolle's publication Upon the death of Romanus in 1806, his personal herbarium was sold with some material being incorporated into his father's collection.
