  1. Ecological Research. Angelina Rowell, James Cook University, Cairns. Studied the relationships between Myrmecodia beccarii and Philidris ants in North Queensland mangroves. She reported (pers. comm.) that resident ants actually castrate their home plants by cutting up its flowers and transporting resultant pieces to their nests within tubers. Angelina found more buds and flowers were produced on ant-colonised, thus well-fed plants, so more fruit should develop on them. Yet, there were more fruits on uncolonised specimens, even though their bud and flower numbers were nutritionally constrained through a lack of ant feeding. Therefore, ants must be removing flowers before pollination, resulting inevitably in lower fruit/seed numbers. Furthermore, Angelina found that ants only removed flowers from their host plant, not from nearby uncolonised plants. Angelina’s Anova statistical analysis, showed that there was no significant difference between the fruit number on colonised versus uncolonised plants (i. e. fruit production is equal). Therefore, ants are not increasing home plant reproductive output. To belabor a point, trophic benefits that the plants are getting from their ants is not transferred to greater seed production because of flower castration. There are greater numbers of leaves on colonised plants, which in theory translates to a greater growth rate in the plant tuber and bigger domatia. But this project did not have enough time allocated to measure increase in plant growth. In summary, more buds, flowers and leaves on colonised plants does not result in more fruit and seed production. Angelina also noted on another thread. "We are looking at the spined form that occurs in the Cairns area. It seems that the majority of the flowers that are left on the plants by the ants develop into fruit. Not 100% sure if it is self pollinating - yet .....The ant interactions with this species is very interesting." I have tried to find more information on line but have not been successful. Attn Dr Guillaume Chomicki. This surely is important to the field of mutualisms.? It is very probable that resident ants are deliberately improving the growth rates of home tubers.

  2. It is sad that too many members of ant-plant circles seem focused primarily on the acquisition of plants with little regard for an acquisition of knowledge. Certainly, unless I duplicate information here, that I have already disseminated on my Facebook group. It DOES NOT get shared. For example, I have posted an update to my section (it took weeks of long day's work) on "Other Ant-plant Families" which now lists probably all known Neotropical ant-plant Melastomataceae (including terrestrials) plus additions to other Neotropical ant-friendly families. I have vastly extended this section due to an influx of South American members (mostly academics) into my Facebook group because my tome is being translated into Spanish. There is an automatic Dropbox link on my group to this rather large section. https://www.facebook.com/groups/498723016920977/ I regularly promote this group but I am not aware of any reciprocation. And let us be honest, it is mostly moribund. Another fascinating fact is the VERY NOVEL presence of extrafloral nectaries in Myrmecodia horrida. See. https://doi.org/10.1007/978-3-319-90306-4_10-1
  3. Aurelien. May I use a few of these photos in my tome.
  4. Thanks for this. I have removed it from my tome.
  5. Neotropical Myrmecophilous Melastomataceae. Most of these names are historic because all members of the tribe Miconieae are now placed in a sole genus Miconia. In my 2020 edition I hope to list all changes under Miconia along with as many synonyms as possible. Most species are shrubs or even small trees but some are hemi-epiphytic and occasionally truly epiphytic, even occurring in ant gardens. However, because they have so much interest to students of myrmecophytes I am listing all ant friendly species in my tome which is mostly reserved for epiphytic species. Allomaieta grandiflora, Blakea austin-smithii, Blakea chlorantha, Blakea formicaria, Blakea involvens, Blakea jativae, Blakea perforata, Blakea podagrica.

  6. Aurelien. Having you back in the group has focused more of my attention here. One result is that I have found more information about this family (only Neotropical spp.) after searching for more information regarding Blakea spp., and ants. There is an enormous volume of information in this study, but it will require many long hours sorting out the epiphytic (and hemiepiphytc) myrmecophytes that I specialize in, because of course many are terrestrial species.

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
  8. I have vastly amended my notes on Poikilospermum cordifolium above, and added more to my 2020 edition of my e/book - data base. Indeed, my chapter on "Other Ant-plant Families especially is already much enlarged as I drill down into leads provided by Aurelien, Jay and Satoshi.

Its low-growing slender flower stems are pale red, and bear many small pink flowers that become blue-black berries. Its possession of pseudobulbs infers it may be myrmecodomic (ant-housing). Habitat/Range. Near rivers at elevations around 213m, (700ft.) in the upper Amazon region. Etymology. Araeococcus is from the Greek araeo, meaning few, and kokkos seed, the genus having the smallest fruit and the fewest seeds in the family. Flagellifolius refers to its whip-like leaves. https://journal.bsi.org/V21/5/ Cultivation, it thrives out doors in southern California.

  13. I am sure that there is much more to learn about ants and bromeliads but this is all I have found regarding this one. Although it may not even be myrmecophytic it certainly grows among such tillandsias. Tillandsia pseudosetacea Ehlers & Rauh. (Renate Ehlers & Werner Rauh) In Tropische und subtropische Pflanzenwelt 58: pp35–37, f.21. (1986). (Trop. Subtrop. Pflanzenwelt). Not yet digitised. Ecology. It occurs with T. occulta, H. Luther, (1997) Type found on a logging road NE of Panuco, Sinaloa, Mexico at 1100m. (3609ft.) along a small stream, epiphytic on Bombaceae in pine/oak forest with Tillandsia caput-medusae (a myrmecodomic species), and T. makoyana (a member of the T. utriculata group thus possibly (probably?) myrmecodomic. http://www.bromeliad.org.au/pictures/Tillandsia/occulta.htm “At the place where we collected, I would guess there were thousands of T. chapalillaensis, hundreds of T. pseudosetacea, tens of T. makoyana and T. achyrostachys and few T. ionantha.” http://www.bromeliad.org.au/pictures/Tillandsia/chapalillaensis.htm Thus, it may only be an ant-plant guild resident.

  14. Thank you Aurélien. Lots of names here to keep me busy while I cope with Covid 19 Lockdown here in NZ. Often when checking new possible epiphytic myrmecophyte names for my Ebook/database, I find even more examples. Quite a few new names that will appear in my 2020 edition (if the virus does not get me - I will soon to be 80) have also been added to my Facebook group because there is currently much interest from South American university students/graduates.

  15. Of course, what I should have done was to search for Antrophyum lanceolatum in the fern section of by E/book, which I would have found listed as a synonym under Polytaenium feei. Thus, saving me a few hours of work. Yes, I certainly cannot remember every name let alone the many details I have added to this large database.
