Especially in Great Britain quite a number of strange specimens recognizable by varyingly darkened limbs and an unordinary flower shape compared to A. pallida are cultivated.
These plants apparently were collected from the Balkan peninsula in Serbia, Macedonia and central Greece. Several closely related species are confirmed to be distributed across this area so it is not unlikely hybridization may be involved there, too.
As it is impossible to manifest this suspect without DNA analysis I will just keep these specimens apart from the 'classic' A. pallida here.
