Leaves spiral, simple; petiole present 5-8 mm long, not winged, attached to base of leaf blade <not peltate>, not swollen; lamina broadest at or near middle stiff, (5.0-) 6.5-10.0 cm long, (2.0-) 3.2-5.0 cm wide; lamina symmetric to very slightly asymmetric, margin finely serrate to dentate (toothed) often recurved, not dissected or lobed, apex acuminate or sub acute, venation pinnate <secondary veins arising from the midrib along its length>, secondary veins open <spaced far apart to easily see tertiary veins>, prominent, intramarginal veins absent; lower surface pale green, upper surface dark green or green, hairs present or absent (by misinterpretation), sparse hairs minute, appressed to leaf surface, reddish brown on lower surface or somewhat dense; oil dots absent; domatia absent; stipules absent.

Flowers: Inflorescence axillary <from between a leaf and branch>. Flowers on a branched axis; flowers bisexual pleasantly aromatic, stalked pedicel 2-3 mm long, with many planes of symmetry <actinomorphic>, 6.0-8.0 mm long, small (< or =10 mm diam.) 6-8 mm diam.; perianth present, with distinct sepals and petals sepals minute, pale brown, pale yellow or pale green; inner perianth 5, free; stamens 5, filaments absent, free of each other, free of perianth; ovary partly inferior <perigenous>, carpels joined (when more than one) <syncarpous>, locules 4; styles solitary <including joined together>, 1.

Notes: The taxonomy of the genus Carpodetus in Papua New Guinea requires review. Tha amount of morphological variation included in material identified as C. major suggests that other species may have been included in the concept of this species.
