tuber flattened, about 2 in. in diam.; stem 2–3 in. high, simple or sparingly branched, comparatively stout, pubescent; leaves 4–8 pairs to a stem or branch, ascending, 2/3–2 in. long, 2–6 lin. broad, linear-lanceolate or lanceolate, acute, tapering at the base into a short petiole, longitudinally folded, minutely pubescent on both sides; flowers solitary at the nodes, comparatively large, nodding or horizontal; pedicels 1–2 lin. long, rather stout, minutely pubescent; sepals 1 3/4–2 lin. long, ovate-lanceolate, acute, thinly and minutely pubescent; corolla ovoid-campanulate, shortly 5-lobed, apparently slightly fleshy, glabrous outside, dull yellow, spotted with dark purple-brown, or (according to Schlechter) sometimes entirely dark purple-brown; tube (according to a drawing) about 6 lin. long and 7 lin. in diam. (smaller in dried flowers), clothed within with long white hairs; lobes free, spreading, about 2 lin. long and 3–3 1/2 lin. broad (in drawing), broadly deltoid-ovate, acute, ciliate with long (vibratile?) pale purple or rose-coloured hairs; outer and inner corona-lobes combined into one series, cupular, pentagonal, apparently of 5 broad 3-lobed segments, with the lateral teeth 1/3 lin. long, deltoid, obtuse, contiguous in pairs with those of the adjacent segments, having near one margin a small patch of minute deflexed white hairs, otherwise glabrous, and the middle tooth (really the inner corona-lobe) 2/3 lin. long, shortly linear from a broadly deltoid base, inflexed and closely incumbent upon the backs of the anthers and not exceeding them, purple-brown. null
