According to a 1952 reference 'Lady Hillingdon' could be confused with 'Souvenir de Mme Boulet' and 'Souvenir de François Graindorge'. Distinction: LH is mostly found in threes, its flower stalk is without prickles, its sepals have appendages; SdMB is solitary, armed with prickles, flower stalk is silky (sericeous), its sepals are glandular, but rarely have appendages; finally, SdFG is also solitary, with darker green foliage, no silkiness on the flower stalk visible except by touching, the first internode is alwysa without prickles.
