Chaenostoma decipiens (Hilliard) Kornhall

Perennial, eventually forming a woody caudex up to c. 10 mm diam. at crown, stems eventually many from the crown, more or less virgately branched, often lax, sometimes densely twiggy, erect to sprawling, c. 220-500 mm long, distinctly to obscurely longitudinally ridged, glandular-puberulous particularly on upper parts including pedicels, with many long delicate glandular hairs as well, up to 0.5-1.8 mm long, leafy, brachyblasts often present though generally inconspicuous. Leaves opposite, bases not connate, decurrent down to the next node forming two very narrow parallel ridges, these sometimes very obscure, largest primary leaves 10-32 x 3-15 mm (measured across spread of teeth) elliptic in outline tapering into a short clasping petiolar part, apex obtuse to subacute, margins usually with 2-4 pairs of coarse teeth sometimes reaching ± halfway to midrib, very rarely teeth obscure, glandular-pubescent, hairs up to 0.5-0.8 mm long. Flowers often but not always solitary in axils of upper leaves but quickly running out into bracteate racemes sometimes branching into narrow panicles, upper flowers often alternate, the rhachis straight or flexuous. Pedicels (lowermost) 6-20(-23) mm long. Calyx obscurely bilabiate, tube 0.5-0.8 mm long, posticous lobes 2.8-6 x 0.4-0.8 mm, anticous lobes slightly broader, glandular-pubescent, hairs delicate, up to 0.4-1 mm long, minutely glandular-puberulous as well. Corolla tube 8.5-12 x 2.5-3.8 mm in throat, narrowly funnel-shaped, limb nearly regular, c. 8-15 mm across, posticous lobes 2.5-5 x 2.2-3 mm, anticous lobe 3-5.3 x 2-4 mm, all oblong elliptic, white to pale pink or mauve, or saxe-blue (type), tube orange or yellow, glandular-pubescent outside, hairs up to 0.25-0.6 mm long, either glabrous inside or weakly bearded with longitudinal bands of clavate hairs. Stamens 4, anticous pair exserted, filaments 1.5-2.5 mm long, posticous pair in throat, filaments 0.8-1.5 mm long, anthers 0.8-1.25 mm long. Stigma 1.5-2 mm long, exserted. Style 7-10 mm long. Ovary 1.3-1.6 x 0.8-1 mm, glabrous or with a few glistening glands on the sutures. Capsules 3.5-5 x 2.5-3 mm. Seeds c. 0.5-0.8 x 0.3 mm, pallid. The chief flowering period is August to October, but there are records as early as March and as late as December.
