As a popular song once said. Two out of three ain't bad.  Note A. myrmecophilus is a synonym.

Ecology/Infauna. Epiphyte with pendent stems often reported in ant gardens along with Lecanopteris or Dischidia. Habitat. Lower montane forest at 1100-2000m (3609-6562ft.)

Range. Currently only recorded on the Malay peninsula but may extend further to Thailand and Sumatra Island.

Aeschynanthus fecundus Woods. (Patrick James Blythe Woods) In Notes from the Royal Botanic Garden, Edinburgh 33: p482. (1975). (Notes Roy. Bot. Gard. Edinburgh.) Not digitised.

Ecology. A retrieval test using 20 seed of this plant species found that Camponotus irritabilis ignored them all. This infers that it is an improbable member of ant gardens but that is surely not conclusive evidence. Seed of Dischidia nummularia in this study (p3) were also totally ignored, yet they are common members of varied ant-plant guilds. However, dischidias parachute seed does not depend upon ants for distribution. http://www.asian-myrmecology.org/publications/am09/weissflog-et-al-2017-am009001.pdf
