Bark bluish-green white and glaucous when young to pale brown, prominently hoop-marked, quite smooth. Stipules deltate, c. 1 by 0.7 cm, thickly coriaceous, spreading perpendicularly to the stem, glabrous or with scattered minute ferrugineus hairs at the base, glaucous, persistent or sometimes caducous. Leaves: petioles terete, slender, 1030 cm long, glabrous, glaucous; blades broader than long to almost rounded, usually slightly convex, 1024 by 1230 cm, deeply trilobed to c. 3/4 of length, rarely with additional basal cusps, the three lobes subequal with the central lobe only slightly longer and broader than the laterals, deeply peltate to 1.54 cm, base broadly rounded sometimes slightly cordate, margin entire sometimes with tiny protrud-ing conical nectaries, apices acute or shortly acuminate, adaxial surface glabrous, abaxial surface white and intensely glaucous with scattered ferrugineus hairs on the veins; 1 venation palmate with 810 prominent veins, 2 venation strongly looping and sometimes ending in prominent conical nectaries at the leaf margin, 3 veins scalariform, 4 and finer veins indistinct due to white wax and not or only weakly scalariform; young leaves dark red-rown, densely covered in minute ferrugineus hairs and scattered with long silvery hairs, soon becoming glabrous, producing food-bodies on lower surface. Staminate inflorescences erect panicles, to 1028(35) cm long, up to 4 axis orders, branching from <1/2 axis length, main axis flattened, first pair of secondary branches ∮ opposite with accessory branches, basal axes glabrous densely glaucous, distal axes moderately to densely covered in crisped ferrugineus hairs; bracts deltate, 36 mm long, margin entire, both surfaces scattered with minute ferrugineus hairs; bracteoles ovate, 2.54 by c. 3 mm, enclosing the flower clusters, margin finely evenly pectinate with >10 short appressed teeth, apex acute, both surfaces densely covered in minute ferrugineus hairs. Staminate flowers 1015 per cluster, c. 1 mm long, shortly pedicellate; sepals 3, fused, densely covered in minute ferrugineus hairs; stamens 1; anthers 4-locular. Pistillate inflorescences 515 cm long, 2 axis orders, branched from near the base, branches short, densely glaucous, basal axes glabrous to scattered with minute ferrugineus hairs, distal axes densely ferrugineus pubescent; bracts ovate-elliptic, 57 mm long, entire or with a finely pectinate apex, covered in ferrugineus hairs, caducous. Pistillate flowers c. 23 mm long; calyx urceolate, c. 1 mm long, glaucous with minute ferrugineus hairs, ovary 3-carpellate; styles c. 1mm long, free, persistent. Fruits 3-locular, sub-globose, 56 by 68 mm, bluish-green, glaucous, two discrete glandular patches on each carpel wall developing into slightly raised disc-like ridges, covered in bright yellow, sticky exudate; pedicel 311 mm long, glaucous, with scattered minute crisped ferrugineus hairs. Seeds 34 mm in diam., spheroidal to slightly flattened, black, with large round shallow pits, encased in a fleshy bright red aril. | |
