A natural hybrid between C. albidus and C. creticus reported from Algeria but also occurring in gardens among seedlings of C. albidus. Leaves usually greener than in that species, narrower and more pointed. ‘Albus’ was raised by Sir Oscar Warburg from a pink form of C. × canescens which had been raised from seed of C. albidus f. albus.
