The code was accepted in principle by the committee, conditional on its approval by a parallel committee of the International Horticultural Congress (the Horticultural Nomenclature Committee), which would next meet in London in 1952 (the "London Committee").[83] Later that year Stearn was also appointed secretary of the London Committee[125][lower-alpha 20] so that he now represented both organisations. The two committees then met jointly on 22–24 November 1951 at the RHS building in London to draft a final joint proposal that was published by Stearn as secretary of an editorial committee and adopted by the 13th International Horticultural Congress the following year.[126]
