Trieenea occulta J.C.Manning & Goldblatt

Short-lived perennial herb or soft shrublet up to 450 mm high, well branched from woody base; stems decumbent or diffuse, up to 2 mm diam. at base; leafy but scapose below racemes, densely glandular-puberulous with patent hairs 0.1-0.2 mm long. Leaves opposite but uppermost alternate, petiolate; blade ovate, 10-20(-30) x 5-15(-20) mm, thin-textured and bright green, deeply lacerate or coarsely toothed, with 2-4(-6) pairs of teeth, occasionally 1 or more primary lobes with smaller secondary tooth (sometimes only on proximal margin), both surfaces glandular-puberulous with patent hairs 0.1-0.2 mm long, base tapering into petiole 4-10 mm long, shorter than blade. Flowers (1-)3-7, subsecund in very lax racemes terminating all branchlets, sometimes 1-few smaller secondary racemes developing to produce an open panicle; pedicels becoming shorter acropetally, 3-7 mm long; lowermost bracts ovate or almost leaflike with one pair of teeth but upper bracts linear-lanceolate, 2-5 x 0.8-2.0(-5.0) mm, glandular-puberulous as in leaves, adnate to base of pedicel only. Calyx obscurely bilabiate, tube 0.5-1.0 mm long, lobes lanceolate, 2.0-2.5 x 0.5-0.8 mm, enlarging in fruit, glandular-puberulous as in leaves, posterior lip split almost to base, anterior lip split ± halfway. Corolla white with mauve or bright blue lobes but whole flower drying pinkish; tube funnel-shaped, 6-7 mm long, cylindric in lower ±4 mm and ±1 mm diam., abruptly expanded above and ±2 mm diam. at mouth, thinly glandular-puberulous outside, limb ±3 mm diam., base of posterior lip thinly bearded with clavate hairs, sometimes extending around mouth of tube below all lobes, lobes ovate to subrotund, posterior lobes ±1 x 1 mm, anterior lobe ±1.5 x 1.5 mm. Stamens 4, inserted ± midway up tube, included, anthers reaching 1.5-2.0 mm below mouth of tube; filaments glabrous, 0.7-0.8 mm long, posterior filaments shortly decur-rent; anthers ±0.4 mm long. Style included, ±3 mm long, reaching slightly beyond anthers; stigma ligulate with marginal papillae, ±1 mm long. Capsules flask-shaped, 4-5 x 2.0-2.5 mm, thinly glandular-puberulous. Seeds up to 20 in each locule, ±0.3 x 0.4 x 0.2 mm, irregularly wrinkled in longitudinal bands, pale watery yellow.
