The New Flora of the British Isles, first published in 1991 with subsequent revised editions, is considered the authoritative and comprehensive flora of the British Isles for the late twentieth and early twenty-first century. It aims to include all the taxa that could reasonably found in the British Isles during the year and also to keep up with developments in taxonomy. The second edition was substantially improved over the first in terms of general appearance, typography and illustrations as well as by including chromosome numbers and an index, as well as species included. As a consequence, by the 2nd edition, 4630 species and hybrid were covered. The native flora of the British Isles comprises around 1190 non-apomictic species, so very many are naturalised species. Line drawings from the second edition onwards, along with some black and white photographs, provide illustrations of key features for some species.^[1]

In 2012 a newly described grass species, Brachypodium stacei (previously regarded as a form of purple false brome), was named in his honour.^[2] In 2019 Stace was awarded the Marsh Botany Award in recognition of his lifetime's work as a plant taxonomist but in particular the fourth edition of his New Flora of the British Isles which has become the standard flora of the British Isles.^[3]
