Plant stemless, somewhat bulbous at the base, growing singly or forming loose groups, flowering up to 70 cm high. Leaves few, forming a flat rosette up to 9 cm high and up to 20 cm, seldom 24 cm in diameter. Sheaths broad ovate, up to 2 cm high and 4 cm wide, white, brownish beneath. Blades narrow-triangular, 8-12 cm long, up to 3.5 cm wide at the base, tapering into a hard, pungent, brown tip, succulent, canaliculate, densely silver-gray lepidote on both sides, strongly nerved on the upper side, laxly serrate with curved, dark brown spines, up to 4 mm long; young blades erect, the elder ones curved back. Scape axillary, up to 50 cm long, reddish-brown, glabrous. Scape bracts: the basal ones subfoliate, the upper ones much shorter than the internodes, lanceolate, acute, soon drying off. Inflorescence 10-15 cm long, simple, rarely branched, with a glabrous, reddish-green rachis and 8-12 laxly arranged, sessile flowers. Floral bracts lanceolate, up to 4 mm long, acute, entire, greenish-brown, glabrous, much shorter than the sepals; these ecarinate, obtuse, bp to 7 mm long, 3 mm wide, orange-yellow, green tipped. Petals up to 1 cm long, ecarinate, obtuse, erect, orange-yellow. Stamens and style included at anthesis; anthers post-floral exserted; filaments white, 8 mm long, free above the short common tube. Style distinct, 1.7 mm long, much shorter than the stamens. Flowers odorless.

Diagnostic Description

It is related to Dyckia mamier-lapostollei, which is also distributed in the state of Goias, and grows in similar localities. D. braunii differs from it in the following characteristics: Plant not forming dense cushions as D. mamier-lapostollei, only loose groups. Rosettes smaller, only up to 20 cm, seldom 24 cm in diameter. Blades narrow-triangular, at the base only up to 3.5 cm wide, densely silver-gray (not white grayish) lepidote on both sides and strongly nerved on the upper side. Inflorescence 30-70 cm long. Flowers smaller, only up to 1 cm long, orange-yellow, not bright orange, odorless (not reminiscent of Trimethylamin). Petals erect; anthers exserted only after flowering.
