Chaenostoma subnudum N.E.Br.

Perennial herb ultimately forming a shrublet arising from a thick woody stock, stems many from the crown, up to 80-450 mm tall, simple or subsimple, soon branching virgately into a lax much-branched panicle, narrowly ribbed, glabrous to minutely puberulous and then sometimes sparsely scabridulous from scattered broad-based hairs, both stems and leaves often shining as if from an exudate, leafy on the lower parts or up to the inflorescence, without brachyblasts. Leaves opposite, bases ± connate or not quite meeting, decurrent down the stem in narrow ridges, another ridge running into the midrib, largest c. 12-35 x 1-2(-2.5-3 mm), often linear, sometimes narrowly elliptic, acute to mucronulate, margins usually strongly revolute, entire, or rarely plane and then sometimes with a few callose teeth, glabrous to minutely puberulous or scabridulous as the stems, gland-dotted on lower surface. Flowers rarely in simple terminal racemes, usually in well-branched twiggy panicles, the branchlets often flexuous. Bracts sharply differentiated from the leaves, lowermost c. 2-2.5 x 1.4 mm, lanceolate, acute. Pedicels (lowermost) c. 3-15 mm long, minutely glandular-puberulous. Calyx bilabiate, tube 1-1.4 mm long, posticous lobes 1.5-3.2 x 0.5-0.9 mm, anticous ones a little broader, glandular-puberulous together with much coarser glandular hairs up to 0.2-0.8 mm long. Corolla tube 3-5.5 x 3-4.5 mm in throat, broadly funnel-shaped, limb almost regular, 7-12 mm across, posticous lobes 2.5-4 x 2-3.2 mm, anticous lobe 3-4.5 x 2.5-4.5 mm, all oblong-elliptic, usually shades of mauve or pink, occasionally a white sport, tube yellow or orange, glandular-puberulous outside, hairs up to 0.15-0.25 mm long, glistening glands as well, 5 longitudinal bands of clavate hairs inside. Stamens 4, all exserted, anthers 1-1.3 mm long, posticous filaments 1.5-2.6 mm long, anticous ones 2.5-4 mm. Stigma c. 1-2 mm long, exserted. Style 4-5.5 mm long. Ovary 1.5 x 0.8-1.1 mm, glabrous or with a few glistening glands on sutures. Capsules 3-4 x 3 mm. Seeds c. 0.7-0.8 x 0.3-0.4 mm, violet-blue. It can possibly be found in flower in any month, but most records are between November and May.
