Description:Species Description - Description based on dry material and on the excellent description by Schott & Endlicher. Monoecious, dark brown parasites with unisexual inflorescences, usually 1 male centrally and 4-10 female ones from each tuber. Tuber subspherical, more or less lobed, 5-7 cm diam., surface verrucose. Stems appearing from lobes of tuber, 5-10 cm long, obconical and at base 1.5 cm diam. increasing upwards to 4-7 cm diam. Leaves scaly, densely imbricate, apparently spirally arranged, in lower part of stem lanceolate, subentire, becoming rhomboid to ligulate above, 9 x 4.5 mm, in uppermost part of stem broad triangular with margin lacerate. Inflorescence depressed into a slightly convex, disciform structure 4-7(-9) cm diam., first covered by imbricate, scaly, apparently spirally arranged bracts. Bracts subpeltate with petiole flattened-canaliculate, 5-8 mm long and 2.5-5 mm wide, pelta subcircular to rhombic, 6-7.5 mm long and 6-9 mm wide, border fringed except in lower subtriangular part, early deciduous and then leaving a horseshoe-shaped scar in the dense layer of filiform, clavate hairs covering the inflorescence; scars soon closing by the hairs being pushed by growing flowers. The area immediately centripetal to (ie above) each bract represents one extremely depressed branch subtended by that bract. Hairs in male inflorescences of two kinds, thinly clavate hairs 1.6-2.6 mm long and very densely arranged, and long subulate hairs 6.5-8 mm long and more loosely arranged (abortive carpels ?); in female inflorescences only the shorter, clavate hairs are found. Male flowers at first buried in the layer of clavate hairs, later growing to 5.8-6.5 mm, with a lower tubular part and a tripartite perianth, segments ovate, concave, 1.3 x 0.8 mm. Filaments connate into a tubular column 4-4.5 x 0.25-0.5 mm. Synandrium ellipsoid to subspherical, 0.8-1.2 x 0.8-1 mm, composed of 3 anthers, each with 2 cells. Rudimentary ovary (?) protruding as a short ovoid-conical structure about 1 mm long into lower part of perianth-tube. Pollen grains spheroid, 6-pantopororate, 54 µm diam., exine 2.1 µm, nuclei 2. Female flowers with perianth adnate to ovary and two short and broad lip-like segments protruding above ovary. Ovary slightly compressed, elliptic, 1 mm by 0.5-0.6 mm; styles 2, 3.5-4 mm long, appearing above layer of hairs; stigmas capitellate. Fruit a small, 1-seeded achene.
