Xanthostemon chrysanthus, commonly known as the Golden Penda or Yellow Penda, is a species of flowering tree in the family Myrtaceae. It is native to the tropical rainforests of northeastern Australia, specifically the regions of Queensland and the Cape York Peninsula.

Here are some key features and characteristics of Xanthostemon chrysanthus:

1. Appearance: The Golden Penda is a medium-sized evergreen tree that can reach a height of about 10-15 meters (30-50 feet) and has a spread of around 5-8 meters (15-25 feet). It has an upright growth habit and a dense, rounded crown.

2. Leaves: The tree has glossy, dark green leaves that are oblong or lance-shaped. They are arranged in an opposite or whorled pattern along the branches and can grow up to 10-15 centimeters (4-6 inches) long.

3. Flowers: The most distinctive feature of Xanthostemon chrysanthus is its vibrant golden yellow flowers. They are borne in large clusters at the ends of the branches and have five petals. Each flower is tubular in shape and approximately 2-3 centimeters (0.8-1.2 inches) in diameter. The tree produces abundant blooms, which can cover the canopy and create a stunning display of color.

4. Fruit: After the flowers, the tree develops small, woody capsules that contain numerous tiny seeds. The capsules are about 1-1.5 centimeters (0.4-0.6 inches) long and have a slightly ridged or warty appearance. The capsules split open when mature, releasing the seeds.

5. Habitat and Cultivation: Xanthostemon chrysanthus thrives in warm, tropical climates and prefers well-draining soils. It is commonly found in rainforests, open woodlands, and along watercourses. In cultivation, it is a popular ornamental tree due to its attractive flowers. It requires a sunny location and regular watering but can tolerate brief dry periods once established.

6. Ecological Importance: The Golden Penda tree is known to attract various pollinators, including bees and butterflies, with its bright yellow flowers. It also serves as a habitat for birds and other wildlife.
