   This member of the Rubiaceae family was described by Odoardo Beccari in 1884. It is found in the rainforests of Papua New Guinea and Cape York, Australia. It is an epiphyte, needs lots of water but not much sun. The caudex will grow to 20 centimetres in diameter, the stems can reach for 30 centimetres. The flowers are white (15 or 16 mm long), and the plant can only be reproduced by seeds.

The genera name means 'ant head'. The species name means 'wide' or 'flat' and turus means 'tire' and then I lost it... It was intruduced by Odoardo Beccari in Malesia Raccolta ... 2: 115. 1884 - which I fail to understand (Italian?).

*)Myrmecodia antoinii, Beccari 1884, has been moved to a subspecies of Myrmecodia platytyrea by Huxley & Jebb in 1993.

SubFamily: Rubioideae
Tribe: Psychotrieae
SubTribe: Hydnophytinae

A key to the genera is found on the Myrmecodia alata page.
