<paragraph pageId="0" pageNumber="1162">Perennial subshrub 1.2-2 m tall. Stems quadrangular, pubescent, more densely so at nodes with eglandular, spreading or retrorse hairs and reddish sessile glands; inflorescence axis also with shorter glandular hairs; young shoots tomentose. Leaves petiolate; blades paler beneath, ovate, 50-120 mm long; 25-40 mm broad, shallowly serrate, base rounded to cuneate, sometimes asymmetric, pubescent with red sessile glands, grey tomentose beneath when young; petioles 8-15 mm long. Inflorescence terminal, branched at base, lax; verticils 2-6-flowered, 5-10 mm apart; bracts inconspicuous, soon deciduous; pedicels 4-5 mm long, spreading, forming a right angle with the calyx. Calyx deflexed, 4 mm long at anthesis, pubescent with reddish sessile glands; fruiting calyx 7 mm long; posterior lip erect; lateral lobes of anterior lip deltoid with posterior margin extended towards posterior lip; median lobes of anterior lip lanceolate, subulate at apex; longer than the lateral lobes. Corolla usually deflexed, pinkish, 10 mm long; tube 7 mm long, straight, dilating slightly towards throat; anterior lip cucullate enclosing stamens. Stamens 4, declinate, enclosed within the anterior lip; posterior pair inappendiculate, glabrous, adnate to the corolla above the midpoint of the tube; anterior pair glabrous, adnating nearer throat, anthers dorsifixed, synthecous. Disk 4-lobed, with anterior lobe larger. Ovary glabrous, deeply 4-lobed; style gynobasic, capitate, branches rounded, equal, adpressed. Nutlets brown, obovate with a small basal scar, minutely tuberculed, producing a small amount of mucilage when wet. Fig. 1.</paragraph>
