Thryptomene pinifolia is a shrub that typically grows to a height of up to 50 mm (2.0 in). Its leaves are linear, about 8.5 mm (0.33 in) long, 0.4 mm (0.016 in) wide and 0.3–0.5 mm (0.012–0.020 in) thick, on a petiole about 1 mm (0.039 in) long. They are prominently glandular and curve upwards. The flowers are arranged in clusters of two or three pairs near the ends of branchlets on peduncles 0.8–1.3 mm (0.031–0.051 in) long. The flowers are about 4.5 mm (0.18 in) wide with broadly egg-shaped, pale pink, petal-like sepals about 1.4 mm (0.055 in) long and wide. The petals are pale pink, about 1.6 mm (0.063 in) long and there are seven or eight stamens. Flowering occurs from October to November.[2]
