Bertya glandulosa is a species of flowering plant in the family Euphorbiaceae and is endemic to eastern Australia. It is a shrub with many branches, narrowly oblong to strap-like leaves, flowers borne singly in leaf axils, and narrowly elliptic capsules with a dark red seed.
Bertya glandulosa is a monoecious or dioecious shrub that typically grows to a height of up to and has many branches. Its leaves are narrowly oblong to strap-like, rarely narrowly egg-shaped, with the narrower end towards the base, long and wide on a petiole long. The upper surface of the leaves is green with a few star-shaped hairs, and the lower surface is white and densely covered with star-shaped hairs. The flowers are borne singly in leaf axils on a peduncle long. There are four to six linear or narrowly egg-shaped to egg-shaped bracts long and wide that are persistent until the fruit matures. Male flowers are on a pedicel long with five yellowish-green, oblong sepal lobes long and wide and have 25 to 30 stamens. Female flowers are sessile with five yellowish-green sepal lobes that are egg-shaped to oblong, long and wide. Female flowers usually have no petals, the ovary glabrous and smooth, and the style is long with three spreading red limbs long, each with three to five lobes long. Flowering has been recorded in January, June and from August to October, and the fruit is a narrowly elliptic capsule long and wide with a single oblong to elliptic, dark red seed long and wide with a creamy-white caruncle.
Bertya glandulosa was first formally described in 1913 by Georg Grüning in Engler's Das Pflanzenreich from specimens collected by John Luke Boorman at Wallangarra. The specific epithet (glandulosa) means 'gland-bearing'.
This species of Bertya grows in open eucalypt woodland or dense open shrubland in the Stanthorpe-Wallangarra area of south-east Queensland and northern New South Wales.
Bertya glandulosa is listed as "vulnerable" under the Queensland Government Nature Conservation Act 1992.
