Note I have seen the type specimen of D. aspera (Aubl.) Benoist and I am certain of its identity with the Central American population. With its scabrous sepals and silica incrusted leaves, which are used like sandpaper by the populace of British Honduras, it is easily distinguished from the smoother D. multiflora (DC.) St.-Hil.
