Characteristics

Yellowish to reddish parasites with unisexual inflorescences. Tuber cylindrical, c. 1 cm ø, swollen up to 3 cm ø at the point of contact with host root, densely patently hairy, less so at swollen parts. Inflorescences surrounded at base by a 5-8-lobed sheath. Inflorescence-bearing stem obconical, 2½-5 cm long, in upper part 3-5 cm ø, in lower part c. 1 cm ø, with numerous adpressed, pergamentaceous, imbricate, scaly leaves. Leaves creamy stramineous to reddish with brown tips, lower ones triangular ½ by ½ cm, upper ones narrowly triangular, up to 5 by 1 cm. ♂ Inflorescence carrying among the flowers reduced, reddish scales with a papillose base. ♂ Flowers 1 cm by 3 mm when not expanded, creamy yellow. Pedicels ¾ cm. Tepals (2-)3, elliptic, boat-shaped, valvate, c. ¾ cm by 3 mm. Stamens (2-)3, epitepalous, filaments united into a tube c. 2½ mm long. Anthers with their connectives united up to ⅓ of their length, ovate-elliptic, emarginate at the base, rounded at apex, c. 4 by 2 mm, 2-celled and horseshoe-shaped with the bend upwards. ♀ Flowers inserted very close to each other, apparently laterally connate in lower parts. Style up to halfway surrounded by a tubular, apically shortly 4-6-lobed perianth up to 1.3 by 0.4 mm; exserted part of the style c. 1.3 by 0.2 mm, surface cells somewhat swollen. Ovary apparently without cavity. The diaspore consists of embryo + endosperm surrounded by 2-3 layers of sclereid cells and is dispersed upon the decay of the infructescence.
