Description
Neoroepera buxifolia is a monoecious shrub or small tree growing to 6 m high. The leaves are elliptic, 1 to 4 cm long, 0.6 to 2 cm wide and evenly spaced along the stems. The flowers are clustered along a short axis and subtended by numerous microscopic, semi-circular hairy bracts. The male flowers are 4.5 to 8 mm long, have 4 to 7 stamens, although usually 6, and ciliate margins on the perianth lobes. The female flowers are solitary, and apical with several male flowers below, 1 to 2 mm in diameter and styles with three distal, flattened, stigmatic portions. The fruit are obloid to obovoid, 5 to 8 mm long, at first conspicuously crowned with 3 long-persisting styles. The seed are usually ellipsoid becoming dorsiventrally flattened with maturity and black when ripe (Henderson, 1992).

Habitat
Neoroepera buxifolia is recorded 60 to 100 m asl. It occurs in gallery or riparian forest, often associated with Melaleuca nervosa, Casuarina cunninghamiana and Livistona decipiens. It also occurs in gallery rainforest with Amorphospermum antilogum and Melaleuca leucadendra. M. buxifolia tolerates periodic inundation, growing on river banks and dry creek beds (Pollock, 1997; Queensland Herbarium, 2012).
Reproduction
Neoroepera buxifolia is known to flower from May to October, and fruits are produced in October (Queensland Herbarium, 2012). Plants set large quantities of seed and are also able to reproduce vegetatively in flooded channels (Batianoff, 1995).
Threatening processes
The main identified threats to Neoroepera buxifolia are vegetation clearing, weeds, mining, grazing pressure and inappropriately managed timber harvesting (Pollock, 1997; DSEWPC, 2012)
Status notes
Neoroepera buxifolia is listed as Vulnerable under the Queensland Nature Conservation Act 1992 and Vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999
Management recommendations
Regional and local priority actions to support the recovery of Neoroepera buxifolia are outlined by DSEWPC (2012). A summary of these include: avoid habitat loss, disturbance and modification (e.g. monitor known populations to identify key threats, monitor the progress of recovery, including the effectiveness of management actions; identify populations of high conservation priority); control invasive weeds (identify and remove weeds in the local area; manage sites to prevent introduction of invasive weeds); minimise trampling, browsing or grazing (manage known sites to ensure appropriate grazing regimes occur, manage total grazing pressure); increase conservation information (raise awareness of Neoroepera buxifolia in the local community); and enable recovery of additional sites and/or populations (e.g. undertake appropriate seed collection and storage).
Additional management for the protection of Neoroepera buxifolia includes: the establishment of a protective buffer (0.3 ha) that excludes clearing with all Neoroepera buxifolia at least 30m inside the buffer (Pollock, 1997).
Notes
Occurs in the following Queensland pastoral districts: Port Curtis.
