Dicliptera maclearii is a species of plant in the family Acanthaceae which is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean. Its specific epithet honours John Maclear, captain of the survey vessel HMS Flying Fish, which visited Christmas Island in 1886.
Dicliptera maclearii is an erect herb with small pink flowers growing to 1 m in height. Its leaves are lanceolate to ovate, acuminate or spine-tipped, 20âÂÂ70 mm long and 5âÂÂ30 mm wide. It closest relative is D. ciliata.
Found only on Christmas Island, it is common in places on the lower terraces of the island, including at Flying Fish Cove and North West Point.
