  1. I am adding Disterigma utleyorum to a 2020 edition of THE BOOK. (Currently it is raining again here) As an ant garden resident it warrants inclusion. I welcome any news regarding other epiphytic species. My impression is that the others mentioned above are terrestrial????
  2. A Van der Pijl 773 (BO) Nengo, Bone Regency, South Sulawesi collection is recorded by H&J p281 as “Pollen and flower characters are also uniform” (referring to all their Sulawesi M. tuberosa variants) “except in Van der Pijl's collection, which also differs in the massive (stiff) black spines, red under sides to the leaves and caducous (quickly lost) stipules. The final treatment of these specimens must await further material.” Perhaps some connection?
  3. KLU I have since discovered is University Malaysia Herbarium, Kuala Lumpur. It seems it is not digitised.
  4. I place this here for obvious reasons. Will the real Myrmecodia bracteata please reveal itself. M. bracteata nom. nud. See M. tuberosa Jack “bracteata”. I have no source for the name of this “variant”. It possibly originates from one of the following collections (H&J p279) but they have proven difficult to locate on line. C. R. Huxley & Jebb, https://www.repository.naturalis.nl/document/565633 Except. Anderson, Jar: S 9873, (1958) On a stunted padang (open area) tree, in the centre of peat swamp. Borneo Island, Malaysia. Sarawak Province, Lobok Pasir, Baram River. Yet both of these Leiden sheets are endorsed M. tuberosa ‘muelleri’ sic. http://data.biodiversitydata.nl/naturalis/specimen/L.2936351 And, Purseglove P4893, Lae, Sarawak, Telok Asam, Bako Nat.

Beccari P.B. 361 (FI.)
  5. So they have removed the evidence of their error rather than fixing it. Typical bureaucrats. Myrmecodia beccarii was recorded on Rio Tinto's land by their own surveyors; so without doubt very rare populations are being destroyed. That is if any are now left.
  6. Have you checked it against this species. H. davisii Jebb & C. R. Huxley, sp. nov. The tuberous epiphytes of the Rubiaceae 7: a revision of the genus Hydnophytum, Blumea 64 p52. (2019).

Tubers large (to 30x20 cm.), chambered and reminiscent of the amazing terrestrial species H. caminiferum in having chimneyed entrances, yet this species is epiphytic. Branches to 1m. long, flowers sessile in leaf nodes, with an iridescent quality, corolla rich in raphides, perianth in fours, fleshy and fragile. Corolla throats white-hairy, 5 mm across, with yellowish anthers. Habitat/Range. Mid-montane primary forest on ridge of granites and volcanic sediments. On stunted, 10 m. (33 ft.) leaning Nothofagus (Southern Beech) trees, rooting on the underside of branches in moss. Trail from Andjai to Gunung (Mt.) Nettoti near Base Camp 2, at 1740 m. (5709 ft.) Kebar Valley, Manokwari District, West Papua Province, West New Guinea Island. Infauna. Unknown but no ants recorded.

Schlechter 20119 Note error. https://plants.jstor.org/stable/10.5555/al.ap.specimen.s05-11012 I find it difficult to accept that this collection belongs in H. moseleyanum.
  14. H. rium Jebb & C. R. Huxley in press. http://pharmacy.utah.edu/ICBG/pdf/WebResources/ForestBiodiversity/Johns-2009-Milne-Bay-flora.pdf This was probably an intended manuscript name but it was not published by Jebb & C. R. Huxley in their (2019) Hydnophytum revision. https://www.repository.naturalis.nl/document/669947 Notes In lower montane forest at 300 m (984 ft.) on Sudest and Rossel Islands, Louisiade Archipelago, Milne Bay Province, PNG. This specific name is probably derived from Mt Riu on Sudest Island. (Johns et al. 2009.) No herbarium specimens found thus it seems very probable this is now H. orichalcum.
  15. Jason. I suggest you browse a few photos of M. schlechteri growing in their natural habitats where they often experience months of drought especially during El Nino weather phases. During such the western tropical Pacific Ocean nations experience very dry conditions while the Americas experience floods. Your plant is not recognizable in its current condition. You need to study a lot more about the best ways to cultivate these plants. Furthermore, changes to cultivation regimes should never be very sudden. Your plants need time to adjust to less water, much better airflow and probably better nutrition. Ants are great providers.
  16. H. papuanum Becc. (Odoardo Beccari) Malesia 2, p124 (1884) f p147, t36, (1885.) http://www.biodiversitylibrary.org/page/44197923#page/261/mode/1up Tavola 36 http://www.biodiversitylibrary.org/page/44197923#page/159/mode/1up Species Conspectus http://www.biodiversitylibrary.org/page/44197923#page/238/mode/1up Update.

  17. H. montivagum West New Guinea, Papua Province, Beaufort River, collector A. Pulle, #307 (1912.) This herbarium sheet was labelled H. streimannianum but was endorsed H. montivagum Huxley & Jebb in 1991 but this name is not used in their 2019 revision. http://data.biodiversitydata.nl/naturalis/specimen/L.2913589 Update. However, there is a mention of the collection Pulle 307 under H. ellipticum Merr & Perry which presumably is its current status. I quote “Pulle 307 reputedly comes from low altitude (80 m), and although this may be correct, it is also possible that the measure represents camp data rather than the actual collection site”. See Jebb & C. R. Huxley in The tuberous epiphytes of the Rubiaceae 7: a revision of the genus Hydnophytum, Blumea 64, p39. (2019.) Pulle 307 http://bioportal.naturalis.nl/specimen/L.2913588 And http://bioportal.naturalis.nl/specimen/U.1561889 Papua New Guinea; Southern Highlands Province, 3k. SW of Erave on ridge top, E of path from Erave to Sawmilli. The collection “Jebb 429” is also assigned to H. ellipticum on p38 of their revision. http://bioportal.naturalis.nl/specimen/L.2913587 Other collections still listed as H montivagum on herbarium sheets., Isotype.

  18. Leaf vein numbers are not a useful guide to identify members of the H. formicarum complex. For example, the sunken taxon H. mindorense Merr., has 5 lateral veins. Also, J& H note 3-12 lateral veins on their formicarum concept in the recent revision. Leaf shape also is a poor guide especially for some of the Philippine taxa which i suspect will become full species. More chromosome counts may be helpful..
  19. H. communis Val. A manuscript name for (1920) Lam collection 446, West New Guinea Island, Papua Province, Mamberamo River, Pionierbivak at 70 m. (230 ft.) One of a number of camps on this major expedition. Endorsed as H. radicans by C. R. Huxley on the following sheets. Lam 446 http://data.biodiversitydata.nl/naturalis/specimen/L.2913968 Lam 446 http://data.biodiversitydata.nl/naturalis/specimen/L.2913928 There is no mention in Jebb & Huxley 2019
  20. One cannot be sure because of insufficient detail but its probably not H. formicarum.
  21. The crux of this post is that the quoted types of online available specimens are NOT filed as H. terrestris. I can only find the one below which is endorsed H. montis-kani. I found it by using its collector's number, Kairo 459. H. terrestris Jebb & C. R. Huxley, sp. nov. The tuberous epiphytes of the Rubiaceae 7: a revision of the genus Hydnophytum. Blumea 64, pp67/68, (2019.) A member of their Papua New Guinea group. Type Kairo 459, (holotype LAE; isotype A, Bulolo, CBG (Chicago Botanical Garden), K, L, UPNG). Papua New Guinea, Lufa, track to Mt Michael, 5 k. SW Lufa. Errata. Lae Herbarium has this filed as, Hydnophytum montis-kani A. Kairo 459, 12 Apr 1982, Locality: Papua New Guinea, Eastern Highlands: Track to Mt. Michael, 5km SW of Lufa. (06 21 S,145 17 E)” Habitat: Disturbed, Nothofagus (Antarctic or Southern Beech) dominated ridge forest. Habit/Notes: Small, erect branched treelet, height 15m??? Presumably its perch height. Leaves dull dark green above, dull green below, flowers white, fruit brownish..
  22. Further to this thread. Here are two herbarium specimens attributed to H. angustifolium by Adolph D. E. Elmer in 1910. Collection not type. Elmer (1910) Philippines, Sibuyan Island, Capiz Province, Romblon, Magallanes (Mt. Giting-Giting) http://data.biodiversitydata.nl/naturalis/specimen/U.1561946 http://data.biodiversitydata.nl/naturalis/specimen/L.2913092 Update. Jebb & C. R. Huxley have referred these two specimens to H. formicarum in their recent revision. I am not convinced.
  23. Note these four names are listed as new synonyms on page 41. Hydnophytum kochii Val. (1911) syn. nov. H. ledermannii Val. (1927) syn. nov. H. nigrescens Merr. & L.M.Perry (1945) syn. nov. H. contortum Merr. & L.M.Perry (1945) syn. nov. Three of these are also listed as var. nov. H. ledermannii p44, H. nigrescens p45, and H. contortum p43. H. kochii is shown as a synonym of var. petiolatum on p42 but is not a new variety. I presume this is correct nomenclature, but it is confusing.
