Yes Jay, exactly what I thought.

H, ferrugineum was known to Huxley et al. back in 1978 but was not described due to the specimen lacking fruits. As far as I am aware it was Paul Forster that collected fruiting examples but I no longer have my source for that information. Furthermore, I have not been able to access the herbarium sheets. I suspect very strongly that Paul made an error. http://www.jstor.org/stable/41738963?seq=1#page_scan_tab_contents I hope to visit its habitat next year.

Rita & Jay. The type description states the fruit is white. Something is not right here. Maybe we have another new species or Paul Forster made an error.

Excellent and there is even more because I think i can see an orchid pseudobulb to the left of the trash basket roots, it is possibly a myrmecophyte??? The other twiggy epiphyte also looks interesting.

He created the first reliable map of whole Java and countless of particular maps of Javanese regions, including the Dieng Plateau. He was also the first who mapped the southern Batak territories on Sumatra. A breakthrough in botany was his successful cultivation of Peruvian bark trees (quinine production) on Java. Junghuhn's writings are among the best of the world’s geographic literature and influenced many scientists. His main work "Java, seine Gestalt, Pflanzendecke und innere Bauart" (1857) contains an incredible variety of detailed information on Java's nature.” http://www.asienreisender.de/junghuhn.html

I don't have much faith in WCSP etc., lists, simply because their task is so truly astronomical in size and complexity. Just looking at possible names for the genus Hydnophytum is a daunting job but these data bases are working on entire plant families with enormously more genera. Also WCSP & IPNI don't show the decades of Huxley & Jebb's work, due to its current lack of publication. One day perhaps we will have programs controlled by very advanced (AI?) computers that can help we humans sort though such massive volumes of data. Because both spellings were published in Malesia 2. I had considered they would have the same publication date but it seems my (lazy) assumption is probably wrong. I must check exactly when the sections of Malesia two were published. That these names have not yet been relegated to synonyms of H. radicans is again because of the lack of a published revision. There are many other examples. A few days ago I contacted IPNI with a query; If they prove to be helpful I will continue to liaise with them but so far no reply.

H. keiense Becc. (Odoardo Beccari) in Malesia raccolta 2, p131, (1885), (Malesia 2.) http://www.biodiversitylibrary.org/page/44197640#page/245/mode/1upType collection was on the Kei Islands, in the Moluccas, Indonesia, (Isole Kei. Kei Bandan a Weri) Kiense or kejense Becc. The above spelling was used in Beccari’s type description on p131; however, on p123 and on tavola 31, he spelt it as H. kejense, which is undoubtedly THE typographical error because of the plants collection location, which is Kei (an island.) The Latin suffix ense means "of from or relating to"; therefore, keiense was surely the intended epithet. Furthermore, Beccari himself used the name H. keiense on the following Type sheet. http://plants.jstor.org/stable/10.5555/al.ap.specimen.fi008894 The forest resources of the territories of Papua and New Guinea, p138, (1925).

However, the name is now a synonym of H. radicans. http://plants.jstor.org/stable/10.5555/al.ap.specimen.k000761921 H. kejense Becc, (Odoardo Beccari) in Malesia raccolta 2, p123, tav. xxxi (31), (1885).

It is not "H.mamberamoense". Compare the petioles, they are drastically different. http://www.europeana.eu/portal/record/11619/BOTANY_NBCNL_NETHERLANDS_BRAHMS_NHN419229.html?query=hydnophytum+&qt=false

I suspect that in this example, the domatia are much too small to contain ants. http://www.eeb.cornell.edu/agrawal/pdfs/1997/Domatia-1997.pdf

"Taxonomy, phylogeny and biogeography of the ant genus Tetraponera (Hymenoptera: Formicidae) in the Oriental and Australian regions." https://archive.org/stream/ants_09575/9575_djvu.txt The ant species, "Tetraponera tucurua is known from only two localities in southeast Queensland (Fig. 196). At the type locality it occurred in a small patch of closedevergreen forest ('vine forest') in a gully, with Eucalyptus overstorey. Here the species was found living inside live terminal branches of a sapindaceous tree, Cupaniopsis anacardioides, whose pith had been removed. The cavities so occupied contained adult workers, alates, brood and scale insects (Myzolecanium sp.). The workers would sting when molested. On a Cupaniopsis sapling I observed several dealate queens (one with a hindwing still attached) walking over new shoots. There were also dealate queens inside some of the new branches of this same sapling, each in a separate excavated cavity with an exit hole. Thus, it appears that colony-founding queens of T. tucurua chew their way into new shoots of Cupaniopsis, and mature colonies later occupy multiple branches. The species was briefly discussed in Ward (1991), using the appellation 'Tetraponera sp. PSW-77'." EDIT. A common name for this popular tree in Australia is Tuckeroo. http://en.wikipedia.org/wiki/Cupaniopsis_anacardioides.Terrestrial myrmecophytes seem to be very rare in Australia. This is the only instance I have located so far. EDIT. Now see also Psydrax.

http://www.agriculture.gov.au/biosecurity/mail/cant-mail The ICON database (next) lists all plants allowed into Australia. If a species is not on the list then special application must be made which is expensive and can be slow. http://apps.daff.gov.au/icon32/asp/ex_querycontent.asp There are also restrictions between Western Australia and all other States due to its differing climate in the south. That is winter rains.

Here Vidal (Sebastián Vidal y Soler) merely mentions a Dischidia sp., in Revision de plantas vasculares Filipinas: memoria elevada al Escmo. Sr. Ministro de Ultramar. http://www.biodiversitylibrary.org/item/51599#page/198/mode/1up Here only a key to genera. http://www.biodiversitylibrary.org/item/56423#page/212/mode/1up Edit. And of course vidalii being an honorific was probably used by someone other than Vidal (and in the example where Odoardo Beccari used it on page 272 above).

No, the "dahlii" form on the Gazelle Peninsula in its many manifestations has distinct differences to the "salomonensis" form in its varied manifestations. Also the clypeoli in general were rather indistinct. These few photographs only provide a tiny insight into this taxons variability.

One hopes there may be more information in Spanish or Portugese publications but although the Facebook Ant-plant group has a number of multilingual members, I doubt very much if any of them did any searching of their 'local' sources. Certainly nothing was ever posted.

Some caution may be needed here. I would not be surprised if a number of Myrmecodia taxa are grown in these gardens. Herbarium Bogoriense is a world renowned resource. http://www.biologi.lipi.go.id/bio_english/mTemplate.php?h=1 http://en.wikipedia.org/wiki/Bogor_Botanical_Gardens http://lewatmana.com/lokasi/3781/herbarium-bogoriensis-museum/

Hello Aurelien. My Squamellaria photos were taken in August 2013. Since then at least two forum members have visited Taveuni Island to see and photograph these plants so there are some small benefits from our sharing. However, we now need more members to follow up on my visit to Bougainville Island in the Solomons and Papua New Guinea.

Correct name Dischidia pectenoides H. Pearson published in the Journal of the Linnean Society, Botany, vol.35, p377, (1902). With a Type Description in Latin as was then required. http://www.biodiversitylibrary.org/page/335444#page/392/mode/1up Synonym, Dischidia vidalii Becc. (Odoardo Beccari) a name used in Malesia Raccolta 2, pp272/3, (1886) with no type description, thus it is nom nud (a naked name.) http://www.biodiversitylibrary.org/item/151443#page/408/mode/1up See bottom of p272. More background, An enumeration of Philippine flowering plants, vol.3, p343, (1923.) (Enum. Philipp. Fl.) or sometimes (EPFP.) http://www.biodiversitylibrary.org/page/33502741#page/355/mode/1up Journal of Botany British and Foreign, vol.40, p270, (1902). http://www.biodiversitylibrary.org/page/35243293#page/343/mode/1up Journal Linnean Soc. Vol 35, p376, (1901/1904) http://www.biodiversitylibrary.org/page/335444#page/391/mode/1up. With hints of possibly more saccate species. Description. Domatia leaves are particularly inflated and again of the double cavity form seen in D. complex and it has attractive red flowers, probably a rarity in this little known genus where most flowers appear to be white. Habitat/Range. The Zambales Range and Bataan, Rizal, and Laguna Provinces on Luzon Island, Northern Philippines, where it frequently grows on the dead stems of climbing bamboo. Also frequently spelt pectinoides which is WRONG. Edit. Furthermore, I can find no illustration in Malesia 2 that could be accepted as a leptotype.

I have re posted an improved copy of my original post.
