Description
editArgyrodendron actinophyllum is a tree that typically grows to a height of 50 m (160 ft) with prominent buttress roots and dark grey or very dark grey bark. The leaves are palmately compound with 5 to 9 lance-shaped leaflets, sometimes the narrower end towards the base, 100–180 mm (3.9–7.1 in) long and 15–50 mm (0.59–1.97 in) wide on a petiole 30–50 mm (1.2–2.0 in) long. The flowers are arranged in many-flowered panicles that are longer than the leaves. The fruit is an oval samara 5–7 mm (0.20–0.28 in) in diameter, with a wing 40–60 mm (1.6–2.4 in) long and 15–25 mm (0.59–0.98 in) wide.[3]
Taxonomy
editThis species was first formally described in 1875 by Ferdinand von Mueller who gave it the name Tarrietia argyrodendron var. actinophylla in his Fragmenta Phytographiae Australiae.[4] In 1935, Herbert Leeson Edlin raised the variety to species status as Argyrodendron actinophyllum in the journal, New Phytologist.[5][6] The specific epithet actinophyllum means 'spoke of a wheel-leaved'.[7]
In 1969, Lindsay Stuart Smith described the subspecies Argyrodendron actinophyllum subsp. diversifolium, and the name, and that of the autonym are accepted by the Australian Plant Census, but not accepted by the National Herbarium of New South Wales:
Distribution and habitat
editBlack booyong grows in warm rainforest, mostly above 600 m (2,000 ft), north from Gloucester in New South Wales[3] and in north-east and central-eastern Queensland.[10]
