Description
Description - Trees up to 15 m tall; latex white to greenish. Leafy twigs 1-4 mm thick, glabrous or with few appressed yellow hairs. Leaves oblong to lanceolate, sometimes broadest near the lower or near the upper end, distinctly to little inequilateral, 8.5-20 cm long, 3.5-7.5 cm broad, chartaceous to subcoriaceous (to coriaceous), acuminate, acute to obtuse at the base, glabrous or nearly so; veins slightly prominent to plane above, costa and secondary veins more or less prominent beneath, 14-18 pairs of secondary veins, few or many parallel tertiary veins; petioles 3-12 mm long; stipules 4-1o(-15) mm long, yellow (sub)sericeous. Staminate inflorescences 8-12 mm in diameter, globose when juvenile; involucre with 24-28 reniform to deltoid to ovate to oblanceolate to linear, obtuse, yellow sericeous bracts in ca 6 series; filaments 0.5-1.5 mm long, anthers 1.4-2.0 mm long, 0.4-0.6 mm broad, often inequilateral, not or shortly apiculate, with apical hairs; interstaminal bracts 3-4.5 mm long, linear to narrowly spathulate, acute, hairy outside. Pistillate inflorescences 2-2.5 mm in diameter; involucre with 10-16 deltoid to ovate, obtuse to acute, yellow sericeous bracts in 4-6 series; perianth 2-3 mm high, subsericeous, style 1.2-2.0 mm long, stigmas 7-9 mm long. Fruiting perianth ellipsoid, ca 11 × 6-7 mm, with few appressed yellow hairs towards the tip.

Discussion
P. murure is closely related to P. macrophylla. It differs from the latter in the sparse indument of the twigs, leaves, involucral bracts, and fruiting perianth, the thinner leaves and twigs, and the less prominent scars of the stipules. The number of involucral bracts of the staminate inflorescences is smaller than in P. macrophylla. The receptacle of the staminate inflorescences is plane, being concave in P. macrophylla.
