The description of this species by Bean (2004) is reproduced here with permission. The species concept of Bean is narrower than that of Symon and species treated as S. nemophilum by Symon are now also encompassed in S. hapalum and S. innoxium .
Erect, rhizomatous perennial shrub, 0.3–0.6 m high. Juvenile branchlets with 0–5 prickles per dm, 2–3 mm long; leaves (in outline) ovate, entire; lamina c. 4 × 2 cm, with 0–4 prickles on upper surface. Adult stem prickles absent. Adult branchlets white or grey; prickles absent; stellae very dense, 0.3–1 mm diameter, stalks 0–0.6 mm long; lateral rays 7 or 8, porrect; central ray 0.7–1.2 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent.
Adult leaves ovate, entire; lamina 2.5–7 cm long, 1.2–2.8 cm wide, 1.8–3 times longer than broad, apex obtuse or acute, base obtuse or cordate, oblique part 0–3 mm long, obliqueness index 0–5 percent; petioles 0.4–1.4 cm long, 15–35% length of lamina, prickles absent. Upper leaf surface grey-green; prickles absent; stellate hairs distributed throughout; protostellae absent; ordinary stellae dense, 0.1–0.3 mm apart, 0.4–0.7 mm across, stalks 0.1–0.3 mm long; lateral rays 7 or 8, porrect; central ray 0.7–1.8 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent. Lower leaf surface green or yellowish; prickles absent; stellae dense to very dense, 0.05–0.15 mm apart, 0.5–0.7 mm diameter, stalks 0.2–0.4 mm long; lateral rays 7 or 8, porrect; central ray 0.5–1.2 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent.
Inflorescence supra-axillary, pseudo-umbellate, common peduncle 0–3 mm long; 3–5-flowered, with all flowers bisexual and 4 or 5-merous; pedicels 4–7 mm long at anthesis, same thickness throughout, 0.9–1 mm thick at midpoint, prickles absent. Calyx tube 1–2 mm long, lobes elliptic, 2.5–7 mm long; prickles absent at anthesis; stellae very dense, white, 0.4–1 mm across, stalks 0–0.25 mm long, lateral rays 7 or 8, central ray 0.8–1.2 times as long as laterals, not gland-tipped; finger hairs absent; Type 2 hairs absent. Corolla purple, 7–10 mm long, rotate or shallowly lobed, inner surface glabrous; anthers 3–4 mm long; ovary with Type 2 hairs only; functional style 5.5–8 mm long, erect, with Type 2 hairs only.
Fruiting calyx with lobes exceeding mature fruit, prickles absent. Mature fruits 1 per inflorescence, globular, 4.5–9 mm diameter, red, glabrous or with a few scattered Type 2 hairs, 1-locular (septum absent or incomplete); placenta not apparent; mesocarp juicy, succulent; exocarp 0.2–0.25 mm thick; pedicels 6–11 mm long in fruit, 0.8–1.2 mm thick at mid-point; seeds pale yellow, 2–2.3 mm long.
Distribution and ecology
Occurs on western slopes of ranges in south-eastern Qld, and rarely from north-eastern N.S.W., on stony outcrops, in granitic and basaltic soil. Associated with margins of vine forest, brigalow and lancewood (Acacia spp.) and Eucalypt woodland.
Closely related to S. densevestitum F. Muell. ex Benth.; distinguished by generally smaller parts, especially calyx-lobes, and denser tomentum (Symon 1981).
Bean's (2004) treatment of this species is narrower than that given in Purdie et al. (1982). In Bean's concept, S. nemophilum is confined to Qld and distinguished from the other 6 species of the S. densevestitum group by the possession of a stellate hair type on both surfaces of the leaves in which the stalk is long and the lateral arms of the stellate hair are similar in length to the central one.
The illustration (fig. 52, p. 145) labelled as S. nemophilum in Symon (1981) is S. tetrathecum .
