Information
subshrub, 1–2 ft. high; stem much-branched from the base; branches wiry, more or less dichotomously divided, slender, minutely pustulate, terete, with rather long internodes, glabrous; leaves very small and subulate, closely adpressed to the stem, acute, about 3/4 lin. long, mostly rather black when dry, glabrous; inflorescences very slender, subdichotomously branched; cymules 3–6-flowered; peduncle free from the bract; bracts similar to the leaves, the one immediately subtending the flower forming with the two bracteoles a cup-like involucre; bracteoles very small, much shorter than the flower, subulate-lanceolate, acute; flower 1 1/2 lin. long, subturbinate; perianth 3/4 lin. long; segments 1/2 lin. long, triangular, with ciliolate margins, thickened at the apex but not hooded; anthers about 1/6 lin. long; style stout, 1/4 lin. long. null
Distribution
COAST REGION Clanwilliam Div.; river-bed below Kradouw Krantz, Pearson, 5372! Tulbagh Div.; near Tulbagh Waterfall, Ecklon & Zeyher, 55! Worcester Div.; Dutoits Kloof, Drège, 8167a, partly in Herb. Stockholm and Kew, not in Herb. Boiss. Near De Doorns, Hex River Valley, Bolus, 13186!
Notes
Some doubt and confusion in the synonymy of T. juncifolium are occasioned by the fact that under the number Drège, 8167a, there are two different plants in different herbaria, though they are not always intermixed. In the Boissier Herbarium, 8167a is the type of T. dregeanum, A.DC., a form of T. virgatum, Lam., but at Kew and Stockholm two different plants are mounted on the same sheet, one of which is T. juncifolium, and the other is the same plant as the type of T. dregeanum, represented at Berlin by Drège, 8167b. Rhinostegia brevifolia was founded on Drège, 8167, and it is therefore doubtful whether it should be wholly referred to T. juncifolium or to T. virgatum.
