Alectryon subdentatus (F.Muell. ex Benth.) Radlk., Act. Congr. Bot. Amsterdam 117 (1877), as subdentatum , =Sapind. Holl.-Ind. 47 (1879)

Nephelium subdentatum F.Muell. ex Benth., Fl. Austral. 1: 465 (1863). T: Tenterfield, N.S.W., C.Stuart ; syn: n.v. ; Tarampa Hill, N.S.W., L.Leichhardt ; syn: n.v.

Shrub or small tree to 7 m. Branchlets and peduncles densely or thinly villous. Leaf rachis 1.5–4 cm long; leaflets 2–4 pairs, occasionally 1, elliptic or elliptic-obovate, broadly obtuse or subacute, serrulate, denticulate, or subentire, oblique, acute, obtuse or truncate at base, 0.7–9.5 cm long, 0.5–3.5 cm wide, puberulent to glabrescent, lower surface subglaucous; petiolule 1–2 mm long; petiole 0.2–2 cm long. Panicles to 6 cm long, few-branched. Male flowers not seen. Females 1.5–3.5 mm diam.; pedicels 1–2 mm long. Calyx 0.7–2.2 mm long, broadly shortly 5-lobed, pubescent. Petals absent. Fruit sessile, obscurely 2-lobed, transversely ellipsoidal, or 1-lobed, subglobose, 0.8–1.2 cm long, 1.4–2 cm diam., turgid; pericarp drying hard and ±woody, velvety outside. Aril granular. 

Occurs from south-eastern Qld to Gloucester, N.S.W. Found in dry rainforest, usually on foothills and steep, rocky slopes. 

The species is close to Alectryon tomentosus in having leaflets in accrescent pairs with serrulate or entire margins; it differs in its velvety 2-lobed or indistinctly lobed fruits and thick pericarp.

Two fairly close forms have been recognised.

Since publication of the Flora of Australia the Australian Plant Census no longer recognises f. subdentatus for Qld.

(S.T.Reynolds)

Lowermost pair of leaflets well-developed, 5–20 mm above base of petiole; petiole more than 5 mm long

f. subdentatus
