Thorncroftia media Codd
LC Indigenous Endemic

Morphological description

Semi-succulent shrub, c. 0.6 m tall, branching at the base; stems erect, sparingly branched, terete, eventually glabrescent. Leaves petiolate, semi-succulent; blade elliptical to ovate-elliptical, 35-65 x 25-35 mm, tomentose and gland-dotted on both surfaces with simple hairs, apex rounded, base cuneate, margin subentire; petiole 20-30 mm long. Inflorescence terminal, paniculate, fairly dense, up to 250 mm long, 100 mm broad; rhachis glandular-tomentose; bracts persistent, those at the base of the raceme leaf-like, becoming smaller towards the apex and eventually c. 4 mm long, with the flowers axillary, solitary, pedicels 1-2 mm long. Calyx campanulate, glandular, somewhat bilabiate, eventually 5-6 mm long; posticous lobe ovate-deltoid, 2 mm long; anticous lobe subequally 4-toothed, teeth lanceolate-deltoid, acuminate, 1.5 mm long. Corolla tubular with the apex 4-lobed, lilac with the lobes purple- flecked; tube narrowly cylindrical, 20-22 mm long, 2 mm in diam., slightly compressed, shortly glandular- tomentose; posticous lobe erect, obcordate, 5-6 x 4 mm; lateral lobes deflexed, linear-lanceolate, acuminate, 5-6 x 1 mm; anticous lobe cymbiform, 6-7 mm long, eventually reflexed. Stamens 4, filaments free, 3-4 mm long, attached in the throat of the corolla. Ovary 4-lobed, glabrous; style filiform, exserted by 7 mm; stigma shortly bifid. From: Codd, LEW. 1986.

Diagnostic description

In corolla characters and growth habit T. media resembles T. succulenta but, in the latter species, the leaf blade tends to be smaller (16-30 x 15-20 mm) with the margin crenate in the upper half, and the tomentum on leaves and stems consists mainly of dendroid hairs. In T. succulenta the inflorescence is also smaller and denser than in T. media. From: Codd, LEW. 1986. Lamiaceae: A new species of Thorncroftia. Bothalia 16(1): 52-53. [CC BY]

Habitat

On rocky slopes. From: Codd, LEW. 1986. Lamiaceae: A new species of Thorncroftia. Bothalia 16(1): 52-53. [CC BY]

Distribution

Known only from the type gathering (Hardy 966), collected on rocky slopes of the Drakensberg Range in the eastern Transvaal, north-west of the Olifants River poort and more or less due west of Trichardtsdal, and cultivated in the BRI nursery. Access to this part of the Drakensberg Range is difficult, as there are no roads into the mountains between the Olifants River and the road over the mountains at The Downs, some 45 km to the northwest.
