Description, as S. dallachii, from Flora of Australia 29: 157 (1982).
Erect, rhizomatous perennial shrub, 1.5–4 m high. Juvenile branchlets with 30–50 prickles per dm, 4–5 mm long; leaves (in outline) ovate, shallowly-lobed, with 4 or 5 pairs of lobes; lamina 9.5–11.5 cm long, 4.3–5.5 cm wide, with 20–40 prickles on upper surface. Adult branchlets yellow, rusty or brown; prickles absent or present, 0–25 per decimetre, straight, acicular or broad-based, 1.5–5.5 mm long, 7–10 times longer than wide; stellae dense, 0.2–0.3 mm diameter, sessile; lateral rays 7 or 8, porrect; central ray 3–6 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent.
Adult leaves elliptical or ovate, entire or shallowly lobed throughout; lobes 4–6 on each side, obtuse, lobing index 1–1.1; lamina 9–18 cm long, 4–8 cm wide, 2.2–2.7 times longer than broad, apex acute or acuminate, base cuneate, oblique part 0–4.5 mm long, obliqueness index 0–3 percent; petioles 1–3.5 cm long, 8–19% length of lamina, prickles absent. Upper leaf surface green; prickles 0–10, straight, acicular, 1–4 mm long, prickles absent or present on mid-vein only or present on midvein and lateral veins; stellate hairs confined to midrib, or distributed throughout; proto-stellae absent; ordinary stellae very sparse to sparse, 0.25–1 mm apart, 0.2–0.3 mm across, sessile; lateral rays 6–8, porrect; central ray 4–8 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent. Lower leaf surface yellowish; prickles absent; stellae moderate to very dense, 0.05–0.3 mm apart, 0.25–0.4 mm diameter, sessile; lateral rays 7 or 8, porrect; central ray 1.5–3 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent.
Inflorescence supra-axillary, pseudo-racemose, common peduncle 2–8 mm long, rachis prickles absent; 6–18-flowered, weakly andromonoecious, flowers 5-merous; pedicels 4–10 mm long at anthesis, same thickness throughout, 0.4–0.7 mm thick at mid-point, prickles absent. Calyx tube 1.5–2.5 mm long, lobes deltate, 3–4 mm long; prickles absent at anthesis; stellae very dense, yellow or brown or rusty, 0.25–0.35 mm across, sessile, lateral rays 7 or 8, central ray 3–6 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent. Corolla mauve or purple, 6–11 mm long, deeply lobed, inner surface sparsely stellate-hairy; anthers 3.5–4.5 mm long; ovary with stellate hairs only; functional style c. 6 mm long, erect, with stellate hairs only, stellae 0.25–0.3 mm across, lateral rays c. 8, central ray 1.5–3 times as long as laterals.
Fruiting calyx with lobes less than half length of mature fruit, prickles absent. Mature fruits 1 per inflorescence, globular, 20–27 mm diameter, yellow or yellowish-green, 2-locular; placenta in cross-section stalked, anvil-shaped; mesocarp moist but not juicy; exocarp 4.5–6 mm thick; pedicels 19–23 mm long in fruit, 1.2–2.5 mm thick at mid-point; seeds pale yellow, 2.7–3.1 mm long.

Distribution and ecology
Restricted to northern Qld. Occurs in disturbed rainforest and in openings and margins of wet scrub.
Closest to S. macoorai (q.v.) but differing from it by
· longer and denser prickles in juvenile foliage of S. macoorai in comparison to S. magnifolium
· adult leaves of S. macoorai usually with prickles and sparse to moderate indumentum on the lower surface of the leaf, prickles absent and indumentum moderate to very dense in S. magnifolium
· fruits red or orange in S. macoorai , yellow in S. magnifolium
Considered by Bean (2004) to be a member of the S. macoorai group of subgen. Leptostemonum.
The identity of the earlier named S. magnifolium was unclear until Bean's (2004) investigations and accounts for its replacement of the later named S. dallachii.
Derivation of epithet
From magnus, Latin for large and folius, leaf, a reference to the large leaves of this species.
