NOTE The closest morphologically relative of C. aitchisonii is C. suavis Pojark. ( Raei Niaki 2019 ). They share many similar characters, e.g., habit, the large leaves with a villose lower surface, long petiole ( c. 4-12), dense inflorescence (7-15 flowers), and navel open in fruit. C. aitchisonii can be readily separated from C. suavis by its obovate leaves (vs elliptic- rhombic), leaves apex rounded to acute ( Fig. 5A, B ) (vs obtuse), red fruit (vs black), succulent fruits of 7-10 mm diam., (vs non-succulent of 6-8 mm diam. fruit) ( Fig. 5 ). This species occurs in Afghanistan , Pakistan , Kashmir ( Fryer & Hylmö 2009 ) and Iran .
