CAUTION!!!!! Almost all photos of this species on the internet are incorrect. The type sheet is the second photo above and it is absolutely correct!!!!! The Real Angraecum didieri has an an elongate stem carrying in the upper 1/3, very short (smaller than 2" [5 cm]), distichous leaves, smaller flowers than both A elephantinum and A ruttenburgianum and a much more oblong, broader lip.!!!!!!!!

These 4 species, A Didieri, A elephantinum and A ruttenburgianum & A peyrotii are all quite similar but each one differs mostly in the leaves and or in the lip
