Early in the society's existence Martyn delivered a series of lectures to it expounding current botanical terminology. These he subsequently published
He secured election to the Royal Society and set up in practice, apparently as an apothecary, in St Helen's, in the heart of the City of London, augmenting his income by lecturing on botany and materia medica.
His correspondence with Linnaeus, initiated by his receipt from the Swedish naturalist about 1737 of a copy of his recently published Flora Lapponica, was noteworthy. Always a keen Latinist, Martyn devoted his later years to producing an edition of Virgil, with a translation and natural history notes.
