Darwinia capitellata: Darwinia capitellata is a plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia.  It is a bushy, many-branched shrub, very similar to "Darwinia diosmoides" but differs in the arrangement of its flowers, its more branched habit, prominent oil glands on the younger stems and its thinner, paper-like bracteoles.  It was first discovered as a separate species when specimens of it were found to have a larger chromosome number than specimens of "D. diosmoides".

Darwinia carnea: Darwinia carnea, commonly known as Mogumber bell or Narrogin bell is a plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia.  It is a small shrub with narrow, keeled leaves and flowers in groups of about eight, surrounded by yellowish-green to pinkish-red bracteoles.  It occurs in small, isolated populations near the towns which contribute to its common names.  It is the only "bell-flowered" "Darwinia" to not grow in the Stirling Range National Park.
