Threats to the plant include habitat degradation and destruction by feral pigs and goats and non-native plants such as Ageratina riparia, Erigeron karvinskianus, Grevillea robusta, Melinis minutiflora, Rubus argutus, and Schinus terebinthifolius.
In drier areas, M. polymorpha has to compete with silk oak (Grevillea robusta) and fountain grass (Pennisetum setaceum).
Threats to this species include degradation of the habitat by invasive plant species, including daisy fleabane, silk oak, lantana, and basketgrass.
