S. corifolium auct.non F.Muell.: Symon, J. Adelaide Bot. Gard. 4: 135, p.p. (only with respect to Clark et al. 1260).


Prostrate shrub with long runners, rooting at the nodes, with sporadic erect shoots to 30 cm high. Fertile branchlets terete or ridged, pale brown, tomentose, with moderate to dense (branchlet visible) stellate hairs, densely armed with prickles (25-65 per dm of branchlet), each 3-7 mm long, glabrous; stellate hairs sessile, 0.2-0.35 mm diameter, lateral rays porrect, 7 or 8, central ray 0.5-1.5 times as long as laterals.

Adult leaves ovate to elliptical in outline, usually with 2-4 pairs of acute lobes, rarely entire; lobing index 1-1.4; lamina 5.5- 9.5 cm long, 2.8-4.5 cm wide, 1.6-2.3 times longer than broad, apex acute, basally dimidiate, oblique part 0-2 mm long, obliqueness index 0-3%. Petioles 10-17 mm long, 14-29% length of lamina, prickles present. Upper leaf surface dark green, prickles numerous (>30) on midrib and secondary veins; stellate hairs confined to major veins even on developing leaves, 0.2-0.3 mm diameter, sessile, sparse, lateral rays porrect, 6-8, central ray 0.5-1.2 times as long as laterals. Lower leaf surface pale green to pale yellow, prickles more than 10 on midrib and secondary veins; stellate hairs sparse to very dense, 0.25-0.35 mm across, sessile, lateral rays porrect, 7 or 8, central rays uniform in length, 0.2-0.8 times as long as laterals.

Inflorescences cymose, pseudo-umbellate or with short axis, 2-8 flowered, some flowers functionally male, prickles present on pedicels. Pedicels 9-20 mm long at anthesis. Flowers 5-merous. Calyx moderately stellate-hairy, hairs 0.2-0.3 mm diameter, transparent to purplish, lateral rays 7 or 8, central ray 0.5-1 times as long as laterals. Prickles absent from calyx or a few short (0.5-1 mm long) prickles present. Hypanthium campanulate, 2-3 mm long at anthesis; lobes attenuate, 1.5-2.5 mm long at anthesis. Corolla mauve to purple, 15- 20 mm diameter; lobes 5-7 mm long. Anthers 4.0-5.0 mm long. Filaments 0.6-1 mm long, glabrous. Ovary with stipitate glandular hairs on distal half. Functional style 6-7.5 mm long, erect, with stipitate glandular hairs at base; stigma entire. Mature fruits 1 per inflorescence, globular to ellipsoidal, 15-18 mm diameter, yellow-green, glabrous, septum incomplete with placenta confined to central area of fruit; pericarp c. 0.8 mm thick when fresh. Pedicels 21-24 mm long. Seeds 3.5-4.0 mm long, pale yellow.

Distribution and ecology

Found only in NE NSW in the Lismore area where it occurs in rainforest.


Bean (2004) documents S. acanthodapis as being variable in morphology and records that intermediate forms do exist between it and S. serpens .

Both species are unusual in being prostrate. They differ in

Considered by Bean (2004) to be a member of the S. macoorai group of subgen. Leptostemonum.

From the Greek acanthos (prickly) and dapis (a carpet or rug), a reference to the plants resemblance to a prickly green carpet at maturity.
