The Savanna Plant Rachelia, also known as Rachelia glaria, is a species of plant in the family Asteraceae. This plant is native to the savannas of Australia, where it can be found growing in open grasslands and woodland areas. The Rachelia glaria is a perennial herb that grows up to 60 cm in height, with a spread of around 30 cm. It has narrow, linear leaves that are typically 2-5 cm long and 1-2 mm wide, with a sharp point at the tip. The leaves are also covered in fine hairs, giving them a soft, woolly appearance.
Physical Characteristics and Growth Habits
The Rachelia glaria has a number of distinctive physical characteristics that help to identify it. The stems of the plant are slender and wiry, with a smooth, hairless surface. The leaves, as mentioned earlier, are narrow and linear, with a sharp point at the tip. The plant also produces small, yellow flowers that are arranged in a terminal inflorescence. These flowers are typically 5-7 mm in diameter and have a radiate shape, with a prominent disc of tiny flowers in the center. The plant grows from a taproot, which allows it to survive in areas with poor soil quality.
Habitat and Distribution
The Rachelia glaria is found in the savannas of northern Australia, where it grows in open grasslands and woodland areas. The plant prefers well-drained soil and full sun, and can be found growing in areas with a wide range of soil types. It is also relatively drought-tolerant, and can survive for long periods without rain. The plant is typically found in areas with an annual rainfall of between 400-800 mm, and can grow in temperatures ranging from 10-30°C. The Rachelia glaria is also able to grow in areas with high levels of salinity, making it a useful species for rehabilitating degraded landscapes.
