Carmichaelia muritai, coastal tree broom or Clifford Bay broom is endemic to the South Island, and can be found in the vicinity of Clifford Bay, Marlborough on deeply eroded coastal cliffs in coarse, free draining gravel and loess,  and colluvial fans below cliffs. This Nationally Endangered, leafless tree grows 5-6 m tall with a stout trunk up to 250 mm diameter. It has numerous grey-brown branches with the uppermost being erect and lower ones drooping. The branches have smooth bark with raised rings at nodes. Its flowers are white with purple/violet markings, and can be seen from December to January.  Best planted in a free draining, fertile soil, in a sunny, sheltered position. Although it does well in exposed sites, better results seem to be obtained from specimens planted next to a wall or with some shelter from strong winds. Once planted, this species does not transplant well, and it resents any form of root disturbance. Like many native brooms that have evolved in the drier eastern South Island, this species does not thrive in humid climates. Only two small natural populations are known. One is seriously threatened by goats, summer drought, coastal erosion and weeds. The other though thriving is vulnerable to fire. All parts of Carmichaelia muritai, though the seedlings especially, are highly sought after by browsing animals such as possums, goats, sheep, rabbits and hares.
