Ecology and distribution
Trop. Afr.
Biology : Myco-heterotrophic herb; stem whitish to yellowish or pale brown, with clusters of proximally inflated roots 3,5-6 mm Ø, each cluster with 20-70 tubercles, each tubercle ovoid, 0,8-1 mm Ø; stem sometimes branching, ribbed, to 3,8-6 cm long, 1-2,4 mm Ø; leaves few, scale-like, adaxially concave, triangular 2,5-5,3x1,9-3,2 mm; inflorescence 1-3-flowered; flowers epigynous, zygomorphic; fruit a pyxidium with a distending column-like structure, shallowly to broadly triangular, 5,5-6x1,4-2 mm, lifting the placenta, exposing the seeds.
Ecology : Evergreen rain-forest on terra firma with Cola flavo-velutina, Palisota ambigua, Leptonychia echinocarpa, Antidesma vogelianum, etc…, common plants surrounding the locality; population of “A. gabonensis” is about 30 individuals on c. 10 m2; thick layer of organic matter, on nutrient-poor sandy soil covered by numerous decaying branches; a second locality is known about 4 km apart; a total of > 250 individuals is estimated for the two localities; in Cameroon the plant was growing in a thick layer of organic matter with Cola cauliflora, C. verticillata, Garcinia sp., etc…; A. saingeri was growing solitarily; 500-1000 m alt.
  Discovered in 2002 (A. saingei), and 2006 (A. gabonensis), respectively. With affinities to A. winkleri.
