May occasionally hybridise with A. littoralis, near which it often grows. A low, shrubby, suckering form/taxon allied to this species in the heathlands on the North Coast, tentatively labelled as 'possibly A. defungens X A. littoralis' in the herbarium, has been re-identified as A. thalassoscopica.
