Arytera distylis
Arytera distylis, known as the two-leaved coogera or twin-leaved coogera is a rainforest tree of eastern Australia. It grows by streams or in sea side rainforests. It occurs from the Orara River in the Mid North Coast region of New South Wales, extending up to Maryborough in south east Queensland. The twin leaf foliage makes identification of this plant fairly straightforward. The generic name "Arytera" is from the Ancient Greek for '"cup". The fruit valves are of a cup shape. "distylis" from the Latin which refers to the two styles in the flower. Description. A small  tree with a dense, pale green crown. Occasionally reaching a height of over 20 metres (60 ft) tall, and a stem diameter of 35 cm (14 in). The base of the tree is flanged or buttressed. The trunk shape is irregular with smooth greyish bark. Young shoots on the small branches are noticeably hairy. Leaves. The leaves are pinnate and alternate, of one to four un-toothed leaflets. However, usually of two leaflets, hence the common name. Leaflet shape varies, being ovate-oblong, lanceolate or elliptical. The leaf tip can be notched or fairly blunt. Leaflets 4 to 8 cm  long and 1.5 to 3.5 cm wide. The leaflet stalk is dark and can be up to 6 mm long. The main leaf stalk is from 9 to 18 mm long. Leaf veins noticeable on both sides. Three to six hairless domatia form where the lateral veins meet the leaf's midrib. Flowers, fruit and regeneration. Small flowers form between September to October, being cream in colour, on small, hairy panicles. Though occasionally the female flower forms on a raceme. The fruit is an orange/yellow dry capsule, 9 to 13 mm long, maturing from October to February. Inside the  capsule are one to three hairy lobes. One seed per lobe. Seeds are relatively large, 9 mm long, partially covered in orange or red aril. Seeds eaten by rainforest birds including the figbird and regent bowerbird. Fresh seed is recommended for planting. Germination occurs between three and eight weeks.
