Scientific name: Marsdenia araujacea

Marsdenia araujacea was a woody vine. The plant had a covering of fine hairs that were yellow-brown in colour. The large leaves (up to 13 cm long and 10 cm wide) were elliptic or oval in shape, heart-shaped at the base and pointed at the tip, with scattered hairs on the underside. The leaf veins were prominent on the underside of the leaf and the leaf stem was 2–3 cm long (Forster 1996).

The flower-heads were flat-topped, with individual flowers approximately 10 mm long by 17 mm in diameter. The flower stalks were approximately 4 mm long. The petals were bell-shaped, cream in colour, with oval or lance-shaped lobes approximately 7 mm long and 2 mm wide. The lobes were smooth on the inside (Forster 1996).

The stamens (male reproductive part of plant) were fused to the petals for most of their length. The anthers (pollen producing part) had oval-shaped appendages. The style (slender part between the ovary and stigma) was elongated and beak-like in shape at the upper end. The pollen grains were not visible to the naked eye (Forster 1996).

The seedpods were approximately 15 cm long, oval-shaped and tapered at either end (Forster 1996).

Marsdenia araujacea was endemic to far northern Queensland between Cooktown and Ingham, south of Cairns. The type specimen was collected from Stone River, west of Ingham, in 1866. Other specific localities recorded included Rockingham Bay, near Cardwell (1870) and Endeavour River, near Cooktown (1866). This species has not been collected since 1893 (Forster 1996).

Marsdenia araujacea grew in lowland rainforest (Forster 1996).

Marsdenia araujacea flowered in January with fruits appearing three to four months later (Forster 1996).

The reasons for the decline and extinction of Marsdenia araujacea are unknown.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
