stems about 5 in. high, like those of T. piliferum, but apparently with fewer vertical series of spine-tipped tubercles; flowers 1–2 or perhaps more together between the tubercles on the sides of the stems; pedicels 1/2–1 lin. long, glabrous; sepals 1–1 2/3 lin. long, ovate or ovate-lanceolate, acuminate, glabrous; corolla 5–6 lin. in diam., rotate, without a distinct tube, glabrous and smooth outside, finely to very minutely puberulous all over the inner surface, entirely dark purple-brown, or with the part round the corona yellow or orange nearly up to the sinuses (Marloth); united part flattish or saucer-shaped; lobes spreading or ascending-spreading, with recurved tips, 1 3/4–2 lin. long, 1 1/2–2 lin. broad at the base, deltoid-ovate, acuminate, outer corona arising near the base of the staminal column and attaining to about the same level, forming 5 very short entire or notched pouches alternating with the anthers and rising into 5 erect subquadrate or subquadrate-ovate lobes behind the inner corona-lobes, obtusely 3-toothed at the top, with the middle tooth inflexed upon and adnate to the base of the inner corona-lobes, which are 1/6– 1/4 lin. long, linear-oblong, obtuse, incumbent upon the backs of the anthers and about half as long as them. null
