Petioles 3.8–6.2 cm long, 35–55% length of lamina, prickles present.

Upper leaf surface. Upper leaf surface green. Upper leaf surface prickles present on midvein and lateral veins, 4–30, straight, acicular or straight, broad-based, 3–10 mm long. Upper leaf surface stellate hairs absent, hair density absent from surface. Upper leaf surface simple hairs erect, straight, sparse or moderate to dense, not gland-tipped, 1–4 mm long. Upper leaf surface Type 2 hairs present only in vein depressions.

Lower leaf surface stellate hair density absent. Lower leaf surface simple hairs absent or erect, straight, sparse or moderate to dense, not gland-tipped, 1.5–3 mm long. Lower leaf surface Type 2 hairs present only on veins.

Inflorescence. Inflorescence supra-axillary, solitary or sessile (rachis very short or absent). Inflorescence common peduncle absent. Inflorescence 1–5-flowered, with some bisexual and some male flowers. Flowers 5-merous. Pedicels at anthesis 8–21 mm long, same thickness throughout, 0.3–0.4 mm thick at mid-point, prickles present. Calyx tube at anthesis 1–3 mm long. Calyx lobes at anthesis deltate, 1.5–3 mm long. Calyx prickles at anthesis present, 20–30 per flower, 1.5–6 mm long. Calyx stellae absent. Calyx simple hairs present, Type 2 hairs present. Corolla white, 7–10 mm long, deeply lobed, inner surface glabrous. Anthers 4.5–6 mm long. Ovary with Type 2 hairs only. Functional style 5.5–7 mm long, protruding between anthers, glabrous.

Fruits. Fruiting calyx lobes less than half length of mature fruit, prickles 3–7 mm long. Mature fruits 1–3 per inflorescence, globular, 25–45 mm diameter, orange, 1-locular (septum absent or incomplete). Mature fruits placenta not apparent. Mature fruits interior dry, pericarp 2 mm thick. Pedicels at fruiting stage 17–28 mm long, 1–1.4 mm thick at mid-point. Seeds pale yellow, 4.8–5.5 mm long.
