The inflorescence consists of terminal, densely packed, mostly 7 to 15-flowered dichasias . The bracts are leaf-like, with small stipules and 2 to 4 mm long, awl blade. The flowers are fleshy and sessile. The sepals are 5 to 7 mm long, green to reddish brown in color, with broad skin margins, hood-shaped at the tip, prickly and hairy. The stamens are 1.4 to 2.0 mm long. The awl staminodes have a length of 1.2 to 1.5 mm. The ovary is in the middle and sunk into the flower axis at the base. The stylus is 2.0 to 2.75 mm long. The fruit measures 2.0 to 2.5 mm and is narrowly ellipsoidal, densely papillae and orange-brown in color. The seeds are 2.0 to 2.25 mm long, ellipsoidal and dark brown.
The flowering period extends from February to May.
The number of chromosomes is 2n = 28.
