Acridocarpus glaucescens Engl.

Upright sparingly branched shrub, up to 2.5 m. high. Younger branches +/- densely ferrugineous- or greyish-sericeous, older ones usually glabrous, lenticellate. Leaf-lamina linear, linear-lanceolate, oblanceolate, oblong-lanceolate to narrowly elliptic, 1.5-6 x 0.5-1.25(-l.5) cm., acute to obtuse, sometimes finely apiculate, cuneate or attenuate at the base, glabrous to densely hairy (see below), rigidly coriaceous, with revolute margins, with 8-12 pairs of lateral nerves, eglandular or rarely with a pair of small glands beneath near insertion of petiole; petiole 1-3 mm. long, canaliculate, glabrous or somewhat sericeous. Inflorescences on leafy branchlets terminating in few- to many-flowered pyramidal racemes, 3-8(-12) cm. long; rhachis robust, usually +/- densely ferrugineous-sericeous; bracts subulate, 2-2.5 mm. long, persistent; bracteoles subulate, up to 1.5 mm. long, eglandular. Flowers 1.25-1.75 cm. in diameter. Sepals broadly ovate to ovate-circular, rarely oblong-ovate, 2.5-4 mm. long, ferrugineous-sericeous or glabrescent outside, with a pair of circular glands at the very base (sometimes glands much reduced) or with glands on the commissures (altogether 3-5). Petals yellow, broadly obovate to subcircular, concave (spoon-like), 6-10 mm. long, shortly clawed. Stamens with ovate-oblong anthers 4-5 mm. long; filaments rather thick, +/- 1 mm. long, glabrous. Ovary densely sericeous; styles 2, 0.75-1 cm. long. Wing of samara obliquely ovate, obovate-oblong, obovate or elliptic, l.5-2(-2.5) x l.2-l.4(-l.7) cm., sometimes extending round nut to the base.
