Adenandra coriacea Lichtst.

An ascending, much branched, rather dense shrublet, 25-45 cm high. Young branches puberulent, reddish-brown; later glabrescent, defoliated, and marked with conspicuous leaf-scars; finally ash-grey. Leaves sparsely to rather densely set, usually opposite, erecto-patent, not imbricated, glabrous or rarely puberulent; petiole c. 1 mm long, appressed, yellowish; blade ovate to elliptic (rarely oblong), 3.5-12 x 2.5-4.5 mm, entire or somewhat crenulate, usually obtuse, flat, rather thin, with slightly revolute margins, above smooth, below densely covered with 80-250 small glandular dots. Uppermost leaves hardly changed in shape, not forming an involucre. Flowers on 3.5-10 mm long pedicels in usually 2-5-flowered corymbs which are sometimes crowded so as to form an umbel-like synflorescence. Bracts similar to the uppermost leaves or somewhat spathulate. Bracteoles attached well above the middle of the pedicel (usually close to the calyx), spathulate to oblanceolate, 2.2-4.0 x 1.1-1.0 mm, moderately acute, sometimes obtusely carinate, glabrous or rarely puberulent. Calyx 3.5-6.0 mm, divided to c. 80%, green, glabrous or rarely puberulent; segments ovate, 2.8-5.0 x 2.0-8.3 mm, obtuse, overlapping, sometimes ciliate. Petals white inside, suffused with pink to brick-red outside (buds conspicuously pink to red); claw 6.5-3.0 mm long; limb ovate to obovate, 6.5-9.0 x 5.0-6.5 mm, obtuse, glabrous. Staminodes slender, more or less uniformly broad, 3.8-4.6 mm long, patently pilose, clavate towards the apex and tipped by a reddish gland 0.4-0.5 mm across. Stamens: filaments subulate, c. 1.5 mm long, incurved and sparsely patently pilose in the upper part, c. 0.6 mm broad at the base, very thin at the point of attachment of the anther; anthers ovoid, dorsifixed, versatile, 2.1-2.5 x 1.1-1.5 mm, brown, usually glabrous, with a shortly stipitate, capitate to globose gland 0.4-0.5 mm across. Ovary globose, 1-1.5 mm across, upper part papillate, but the pale papillae usually not gland-tipped; style 1-1.5 mm at anthesis, stout, recurved; stigma capitate to discoid, brown. Mature capsule nearly twice as long as the calyx, faintly bullate, light brown. Seeds ovoid, 3.2-3.8 x 2.0-2.5 mm.
