Macadamia integrifolia flowers. The macadamia tree is usually propagated by grafting and does not begin to produce commercial quantities of seeds until it is 7–10 years old, but once established, it may continue bearing for over 100 years. Macadamias prefer fertile, well-drained soils, a rainfall of 1,000–2,000 mm (40–80 in), and ...
Macadamia integrifolia trees grow to 15 metres (49 ft) in height. The leaves are simple, oblong in shape, glossy, entire with wavy leaf margins and are 20 centimetres (8 in) long and 10 cm wide. [3] The flowers are white or pink followed by woody, edible rounded fruits [4] which are 2 to 3.5 cm in diameter.
Macadamia tetraphylla was the first Australian native food plant to be grown by non-indigenous Australians as a commercial crop. The first commercial plantation of macadamia trees were planted in the early 1880s by Charles Staff at Rous Mill, 12 km southeast of Lismore, New South Wales, consisting of M. tetraphylla. [4]
Macadamia ternifolia (common names: small-fruited Queensland nut, gympie nut) [5] is a tree in the flowering plant family Proteaceae, native to Queensland in Australia, [2] [3] and is listed as vulnerable under the EPBC Act. [5] Macadamia ternifolia is a small multi-stemmed tree which grows up to 8 m
This character does not occur in all Proteaceae, however; Adenanthos species, for example, have solitary flowers. In most Proteaceae species, the pollination mechanism is highly specialised. It usually involves the use of a "pollen-presenter", an area on the style-end that presents the pollen to the pollinator. [7] Proteaceae flower parts occur ...
Lasjia species characteristically branched compound inflorescences differentiate them from the Macadamia species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about 1,000 km (620 mi) further to the south, in southern and central eastern Queensland and in northeastern New South Wales.
The larvae of the Macadamia leafminer (Acrocercops chionosema), a moth, burrow along and disfigure the waratah's leaves, and are mainly a problem in lowering the value of cut flower crops. More problematic is the larger caterpillar of another moth, the Macadamia twig girdler ( Xylorycta luteotactella ) which can burrow into and disfigure the ...
A flower that is not part of an inflorescence is called a solitary flower and its stalk is also referred to as a peduncle. Any flower in an inflorescence may be referred to as a floret, especially when the individual flowers are particularly small and borne in a tight cluster, such as in a pseudanthium.
