    Fruit-stalk 0.5–2 mm. long; drupe flattened ovoid or ellipsoid, usually distinctly beaked, sometimes merely acute, 10–13 mm. long (including a 0–3 mm. beak) × 7 × (3.5 + 4) mm.; pseudaril almost entirely surrounding and closely clinging to the rugose stone, sometimes shortly 4-lobed at the tip; stone ovoid, pointed ± 8 × 5 × (2.5 + 3) mm. with small but well-defined apical pits; sterile cell convex, thickest below the middle, resembling the fertile cell but rather smaller, the stone thus appears 4-gonous when viewed from above.

    Leaves all 3-foliolate, often glabrous but sometimes with rather long flexuous golden hairs at the bases of the leaflets and the petiole which is usually about as long as the central leaflet but sometimes, especially on short-shoots, much longer and sometimes on long-shoots much shorter; terminal leaflet obovate or rhombic, rounded or pointed, cuneate-attenuate at the base, 7–35 mm. long, 8–22 mm. wide, with 3–6 deep crenations usually above the middle on each side; lateral leaflets usually similar in shape but 1/3–2/3 as long, sometimes almost orbicular with a wide basal angle and with teeth nearer the base.
