Diagnostic
Although the inflorescence of D. canariensis is superficially similar to that D. vulgaris it appears that D. canariensis has evolved in association with a difierent pollinator. The pale spathe limb, yellow spadix appendix and semen-like odour attract small flies, wasps and small bees (Boyce, pers. obs.) The spathe tube gapes at the front and allows insects direct access to the flowers whereas in D. vulgaris the potential pollinators (large flies, Staphylinid and Scarabidinid beetles) enter the spathe tube and gain access to the flowers by descending the spadix appendix.
