plant similar to T. piliferum; stems 4–10 in. high, 1 1/4–2 1/4 in. thick, with 25–30 series of tubercles ending in stiff pale brown (turning to grey) bristles 1 1/2–2 1/4 lin. long, “dull green, hardly glaucous on the young growth, flowering nearly all over” (Pillans); flowers 1–3 in a fascicle; pedicels 1/2– 3/4 lin. long, 3/4 lin. thick, glabrous; sepals 1–1 1/4 lin. long, ovate, very acuminate, glabrous; corolla 4 1/2 lin. in diam., bright canary-yellow, pinkish-green outside (Pillans), glabrous and smooth outside and within the tube, densely papillate and thinly and very minutely puberulous (always?) on the inner face of the lobes, not ciliate; tube distinctly cup-shaped, or campanulate, 1–1 1/3 lin. long, 1 1/2 lin. in diam. at the mouth inside; lobes spreading, 1 1/3–1 1/2 lin. long, 1 1/2–1 3/4 lin. broad, broadly deltoid-ovate, very acute; outer corona shortly cupular at the base, equally 10-toothed, light yellow; teeth 1/4– 1/3 lin. long, deltoid, acute or obtuse, ascending-spreading, quite straight and equidistant, not approaching each other in pairs; inner corona-lobes 1/4 lin. long, linear-oblong, obtuse, about half as long as the anthers and closely incumbent upon their backs, dorsally connected to the outer corona, light yellow; follicles only developed upon the young growth (Pillans), erect, subparallel, 3 1/4 in. long and 3 1/2–4 lin. thick in the specimen seen, fusiform, tapering into a beak, incurved-hooked at the apex, smooth, glabrous; seeds about 2 lin. long, scarcely 1 lin. broad, ovate or oblong-ovate, with thick margins, often incurved on one side, smooth, glabrous, light brown, with paler margins. null
