Three-leaved Bosistoa was formerly recognised as two species, Bosistoa selwynii and B. transversa (Hartley 1977), with division being based on whether leaves had one leaflet or whether at least some leaves on the plant had three or more leaflets (Harden 1991). Bosistoa transversa and Bosistoa selwynii are now conventionally accepted as synonyms (CHAH 2010; Hartley 2013).

Three-leaved Bosistoa is a small to medium-sized crooked tree that grows to 22 m high and has a dark green crown. Leaves are leathery with 1-3 leaflets elliptic-oblong to broad-elliptic or ovate in shape and cuneate (wedge-shaped) to rounded leaf bases. Leaf bases may sometimes be cordate (heart-shaped) in one-leaflet leaves (Richards cited in Harden 2002). The lower leaf surface is paler green than the upper surface. The lower leaf surface has prominent veins. Small white flowers are borne in loose clusters at or near the tips of the branches. The fruit is hard, ribbed and egg-shaped with a flattened end, and contain a single kidney-shaped seed (NSW OEH 2012aa).

Three-leaved Bosistoa is found from the Nightcap Range north of Lismore in north-east NSW to Mount Larcom (near Gladstone) in south-east Queensland (Connell Hatch 2009; NSW OEH 2012aa). The species is described in herbarium collection records as locally abundant at Natural Bridge-Springbrook NP and Coalstoun Lakes NP in Queensland (Queensland Herbarium 2008b). Connell Hatch (2009) surveyed 70–80 individuals on Mount Larcom Range, near Gladstone. The species has been recorded in the following locations:

Coalstoun Lakes National Park (NP) Mt Warning NP

TR 209 (Rough LA Mt Brisbane)  

Three-leaved Bosistoa grows in lowland subtropical rainforest up to 300 m above sea level (Floyd 1989; Richards cited in Harden 2002; Hartley 1977; Stanley & Ross 1983).

Near Tyalgum, NSW, Three-leaved Bosistoa occurs in a closed forest on a steep slope with a westerly aspect on dark organic loam over basalt. Associated species include White Booyong (Argyrodendron trifoliolatum), Smooth-bark Rose Apple (Syzygium hodgkinsoniae), Hairy Walnut (Endiandra pubens), Shiny Leaf Stinging Tree (Dendrocnide photinophylla), Red Apple (Acmena ingens), Native Tamarind (Diploglottis australis) and Red-fruited Ebony (Diospyros mabacea) (Queensland Herbarium 2008b).

At Mt Warning NP, NSW, Three-leaved Bosistoa is recorded as growing in a rainforest transect along Wollumbin Creek, associated with Ferny-leaf Bosistoa (Bosistoa pentacocca) (Sheringham & Westaway 1995).

At Natural Bridge-Springbrook NP, Queensland, Three-leaved Bosistoa grows on reddish loam over basalt rock on a very steep slope in complex notophyll vine forest with emergent Brush Box (Lophostemon confertus). Associated canopy species include White Booyong, Soft Corkwood (Caldcluvia paniculosa), Rosewood (Dysoxylum fraserianum), Yellow Carabeen (Sloanea woollsii) and Giant Water Gum (Syzygium francisii).

At Triuna NP, west of Woombye, Queensland, Three-leaved Bosistoa grows in complex notophyll vine forest, on brown loamy soils on a hillside with Brush Poison Tree (Excoecaria dallachyana) and Hauer (Dissiliaria baloghioides) (Queensland Herbarium 2008b).

At Buderim, Queensland, Three-leaved Bosistoa has been found in remnant vine forest pockets within highly disturbed and weed infested habitats on a site with varying slope, from relatively flat to a steep scree slope. The species appears to occur only in areas that have experienced minimal disturbance (Queensland Herbarium 2008b).

Flowering occurs from January to May (Floyd 1989; Harden 1991; Richards cited in Harden 2002; Stanley & Ross 1983) and ripe fruits are present from May to November (Floyd 1989). Germination is noted as erratic (Floyd 1989).

Threats to the Three-leaved Bosistoa include (NSW OEH 2012aa):

  • loss of habitat through clearing and fragmentation
  • habitat degradation through weed invasion and disturbance
  • grazing by domestic stock
  • fire
  • timber harvesting.

Refer to the Commonwealth Conservation Advice (TSSC 2008ja) for information on research priorities and recovery priority actions to mitigate threats including habitat loss, disturbance and modification, trampling, weeds and fire.

The NSW Government identify the following recovery actions to assist in the protection of the Three-leaved Bosistoa (NSW OEH 2012aa):

  • Support local Landcare groups and bush regeneration teams.
  • Protect rainforest habitat from fire.
  • Fence creeksides and rainforest areas to exclude stock.
  • Control weeds.
  • Protect remaining habitat from clearing and development.
  • Expand and connect remaining areas of rainforest habitat.

Management documentation for the Three-leaved Bosistoa are found at the start of the profile and also include:

  • Parks and Reserves of the Tweed Caldera, Plan of Management (NSW NPWS 2004a)

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
