About Stackhousia monogyna Labill.
Stackhousia monogyna Labill. is a slender, multi-stemmed perennial herb that grows up to 70 cm (28 in) tall. Its upright or ascending stems are either covered in soft hairs or completely smooth. The leaves are dark green, most are narrow, ranging from linear to lance-shaped, and measure up to 30 mm (1.2 in) long and 2–4 mm (0.079–0.157 in) wide. Leaf apices can be rounded, acute, or end in a short point.
This species produces numerous white, cream, or yellow flowers arranged in a dense, cylindrical spike inflorescence. Each flower is tubular, with five pointed spreading lobes that grow up to 5 mm (0.20 in) long. Flowering takes place from late winter to early summer. The fruit is a broadly oval or ellipsoid mericarp, with a wrinkled or veined surface, that measures 1.9–2.8 mm (0.075–0.110 in) long.
Commonly known as creamy stackhousia, this is a common and widespread species. It grows in grassland and dry forest on gravel, clay, and granite substrates. It occurs in all Australian states except the Northern Territory.
