Macadamia integrifolia, commonly known as the smooth-shell macadamia or the Queensland nut, is a species of flowering tree native to the eastern coast of Australia. Here's a detailed description:

Size and Growth Habit: Macadamia integrifolia is a medium to large evergreen tree that can reach heights of up to 15 to 20 meters (49 to 66 feet) tall. It typically has a dense, rounded canopy with a spread comparable to its height.

Leaves: The leaves of Macadamia integrifolia are simple, alternate, and lanceolate to oblong-elliptic in shape, measuring about 10 to 25 centimeters (4 to 10 inches) in length. They have entire margins (hence the species name "integrifolia") and a glossy, dark green color.

Flowers: The tree produces small, fragrant, creamy-white to pale pink flowers arranged in long racemes or clusters. These flowers have both male and female reproductive parts and are pollinated primarily by bees.

Fruit: The most commercially valuable aspect of Macadamia integrifolia is its fruit, which is a spherical or elliptical nut enclosed in a hard, woody shell. The nut is covered by a fibrous husk that splits open as the nut matures. The shell is extremely hard and smooth, hence the common name "smooth-shell macadamia." Inside the shell is the edible kernel, which is creamy-white and rich in oil.

Cultural Requirements: Macadamia integrifolia thrives in subtropical to tropical climates with well-drained, slightly acidic soil. It requires regular watering, especially during dry periods, and benefits from mulching to retain soil moisture. The tree prefers full sun but can tolerate partial shade.

Cultivation and Uses: Commercially, Macadamia integrifolia is cultivated for its highly prized nuts, which are consumed raw, roasted, or used in various culinary applications, such as baking and confectionery. The nuts are rich in healthy fats and are considered a gourmet delicacy. Additionally, the wood of the macadamia tree is sometimes used for woodworking and produces high-quality timber.
