The inside is rendered attrac-tive to insects by numerous spots of carmine, andhighly coloured veining. The conditions suitablefor C. calceolus also suit C. humile, but it isbetter adapted for the rockery proper, and it maybe well grown between flat boulders in the mannernow considered good for Ramondia.
