Tetratheca glandulosa is a spreading shrub in the family Elaeocarpaceae.

The flowers are solitary (rarely paired) on peduncles which are 3–10 mm long.

The deep lilac-pink petals are 4.5–10.5 mm long and also persist in the fruit.

[3] Tetratheca glandulosa was first described by James Edward Smith in 1804.

The specific epithet, glandulosa, derives from the Latin noun glandula, meaning "gland", to give an adjective describing the plant as "bearing glands" or "gland-bearing".
