- Description
- Auranticarpa edentata is a small to medium sized tree growing up to 20m tall. The rounded canopy only represents the top 5m of the trees height. The bark is thick and grey-brown in colour. Older stems are white and flaky with numerous corky lenticels. The newer stems are white and flaky with horizontal and vertical fissures.
Leaves of juvenile plants are broadly elliptic to ovate in shape, with margins irregularly toothed or slightly lobed and on stalks up to 10mm long. Adult leaves are elliptic to slightly ovate in shape and 65-70mm long by 28-35mm wide, including a leaf stalk 15-18mm long. The leaf margins are slightly scalloped and the tip is rounded with a very small drip tip less than 5mm long.
The multi-flowered, flat-topped flower clusters have a main stalk 20-25mm in length. The individual creamy-white flowers have spatula-shaped petals and are 5-9mm long. The red-orange fruit is pear-shaped and 5-6mm long, on a 1mm stalk, with 2 or sometimes 3 valves. Seeds are black, kidney-shaped, ridged and 3mm by 2mm in size.
This species is similar to the widespread A. rhombifolia except that the canopy is small and rounded, the adult leaves are entire or slightly scalloped and the fruit are smaller and red-orange. (Cayzer 2000) - Distribution
- Auranticarpa edentata is currently known to occur only in the Forty Mile Scrub area, west of Cardwell, north-eastern Queensland. (Cayzer 2000; Herbrecs 2008)
