Named for the iridescent sheen of the flowers. Regarded by many as a form of Aylostera pygmaea or A. steinmannii. Not many accept this as a true species; however, Aylostera iridescens was found to be distinct enough to be given specific status by Mosti & Papini (2011). It is not clear what material was used in their study.
