For typification, specimen citations and external distribution, see the main Flora [8:49-50, as A. elongatum subsp. detruncatum and A. conophalloides]. Most extra-Turkish plants fall towards the 'conophalloides' end of the variation spectrum, with massive appendices. Typical 'detruncatum, with slender appendix, is not known outside Turkey apart from the type.
