Hydnophytum formicarum Jack, Trans. Linn. Soc. London 14: 124 1823. (Syn: Hydnophytum blumei Becc.; Hydnophytum borneense Becc.; Hydnophytum formicarum subsp. blumei Boerl. ………….; Hydnophytum montanum Blume; Hydnophytum montanum var. latifolia Miq.; Lasiostoma formicarum (Jack) Spreng.);
as the ‘Ant Plant’.
The plant belongs to one of the five known genera of tuberous, epiphytic, myrmecophytes (plant that lives in a mutualistic association with a colony of ants) belonging to the tribe Psychotrieae, subtribe Hydnophytinae of the family Rubiaceae.
In India, it is distributed in Andaman. Recently, it was posted by … also but quality of the photographs were unfortunately not upto the mark.
Recently I came across this plant at Nha Trang city of Vietnam (ca 200msl) and thought of sharing the details with eFlora group.
Distribution: Andaman Island, S. Thailand, Myanmar, Cambodia, Vietnam, Malaysia, Indonesia, Philippines, Fiji and the Cape York Peninsula in Australia.
Notes: Listed as critically endangered in Vietnam and Singapore. Probably rare in India too.
Hope you’ll like this post.
Very nice pictures of the interesting plant.
The photographs and info. are great.
Came across this at Sarawak, Borneo. Presume this is the same tree.
Looks same to me!
if it is critically endangered then we should make an effort rescue it through some technique like tissue culture or simply an ex situ conservation effort. those who have access to this plant at any point of time can get some of the tissue sample…
Rubiaceae week: Hydnophytum formicarum at Andaman: This one is also called as “Ant Plant“.
Bot. name: Hydnophytum formicarum
Thanks … for showing this plant again. More details can be found in the thread
Flora of Andaman 11- 311210-PKA2: I had spotted this almost Football size bulb on a Mangrove tree at Baratang (Andaman & Nicobar).

Great. I imagine, I have seen such bigger galls in mangrove only in Bhitarkanika. And I think, there are two different species of orchids too.
Is this not a Hydnophytum or Mymecodia? Antplants that grow epiphytically and can become quite large. It seems like the shoots growing out of the “ball” has the right shape on the leaves.
This is Hydnophytum formicarum of Rubiaceae. Popularly known as ‘Ant Plant’. (Myrmecodia tubers are spiky). Recently I came across this plant in Vietnam where it is listed under the threatened category. It is distributed from Andaman islands to S. Thailand, Myanmar, Vietnam, Malaysia, Indonesia, Philippines and Australia.
This plant is of interest to botanist and ecologists owing to the symbiotic association of ants and the plant.
.. is 100% correct. This is Hydnophytum formicarum (Rubiaceae) the famous ant plant. This plant mostly occurs in Mangrove trees but i have noticed them also in high altitude areas like Mount Harriet, Mount ford and
