Slender small trees to 6(-10) m high, unbranched or few-branched or with several 
stems from the base, each bearing a terminal tuft of leaves; bark brown, corky and 
somewhat scaly. Indumentum persistent on most parts, dense on young fruit and 
shoots, hairs erect, pale brown, irritant; glandular hairs present on margins of stipules. 
Seedling leaves at first simple, margins dentate and becoming Iobed at base, becoming 
pinnate after 12 months growth, hirsute, with some reddish glandular hairs present on 
stipules. Adult leaves (25-)35-80(-120) cm long; petiole 5-20 cm long; rachis 
prominently winged adaxially, wing continuous or as separated segments, (l-)3-4 
(-5) mm wide, becoming more separated on lower rachis as stipella-like outgrowths, 
similarly on petiole, margins irregularly dentate, teeth ± spinose; pinnae (7-)ll-17 
(-19); stipules, 10-30 mm diam., margins dentate; terminal pinna obovate to oblong- 
obovate to elliptic, lateral pinnae mostly oblanceolate to oblong-oblanceolate, with 
basal pinnae ± elliptic, apex acute to acuminate, base tapered and ± equal in upper 
pinnae, unequal in lower pinnae, upper surface dark green and dull, sparsely hirsute, 
lower surface dull and ± hirsute; margins secondarily serrate, each tooth with a hair¬ 
like point; secondary veins 11-17 pairs, prominently raised on both surfaces; terminal 
and subterminal pinnae largest, (6-)20-30H0) cm long, lower pinnae (3-)6-10(-15.5) cm 
wide; petiolules 1-3 mm long; stipellae present at base of most pinnae, lanceolate, 
3—11 mm long, 3—5 mm wide, lower stipellae often 3-lobed, margins glandular¬ 
toothed. Inflorescences usually cauliflorous, mostly lateral on main stems, pendent, 
compressed panicles, often appearing as tight dusters; 4-10(-30) cm long, peduncle 
3-6 cm long, pedicels 1-3 mm long; bracts amplexicaul, 5.0-7.0 mm long, bracteoles 
sessile 3.0-4.0 mm long. Flowers 4- or 5-merous; sepals 4-6 mm long, basally connate, 
dark pink to red, outer surface bristly-hirsute, inner surface pubescent, recurved, 
persistent in fruit; stamens 10, 4.5-6.5 mm long; filaments 4.1-5.5 mm long, anthers 
ellipsoid, 1.1-1.7 mm long, yellow; ovary 1.5-2.6 mm long, styles usually 2, divided to 
base, 4.4—5.6 mm long, glabrous; stigmas minutely capitate. Fruit pyriform to obovoid, 
laterally compressed, 33-45 mm long, 31-37 mm wide, 27-35 mm deep, blue to black, 
glaucous; young fruits hirsute, mature fruits sparsely hirsute with golden-brown to 
fawn hairs 1.0-2.0 mm long; mesocarp dark red; pyrenes usually 2, strongly laterally 
compressed, fimbriate with soft fibres 1.0-2.0 mm long, attached to the pyrene body; 
pyrene body 1.4-1.8 cm long, 0.9-1.5 cm wide, crest 2.1-2.3 mm long; seed 1.1-1.2 cm 
long, 0.8-0.9 cm wide, 2.5-3.0 mm deep. (Fig. 3). 
Habitat and distribution: usually grows in subtropical and riverine rainforest, in 
moderately high rainfall from 1100 to over 2000 mm, at altitudes less than 300 m above 
sea level. Mostly on red and yellow podsolic soils of clay texture, over fine-grained 
metasediments, greywacke, slate, phyllite or quartzite, also on alluvial deposits. 
Confined to north-eastern New South Wales; chiefly from the Brunswick and Tweed 
Rivers catchments, from Mullumbimby north to Urliup, Upper Crystal Creek and 
Settlement Road (Fig. 4).
