It is similar to Senecio tamoides and is known by the same common name. It can be distinguished by the soft leaves which are much paler on the under surface, broadly triangular in outline with very irregular lobes and dentations along the margins, giving the leaves a wrinkled and torn appearence. There are normally leaf-like false stipules present at the base of the petioles. The leaves of S. tamoides are more smooth and slightly leathery and more regularly dentate. No false stipules are present.Senecio deltoideus is a species of more open terrain, such as bracken and ericoid scrub or bush clumps in montane grassland, where it often forms masses on the ground and on lower scrub. S. tamoides is a typical constituent of the evergreen forest edge, where it acts more as a climbing species.
