  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. This work has at times been almost overwhelming. During our wet winters, it is not hard to stay indoors and write, but summer is at last here, so I will be outside a lot more working on my land or cycling our many bike trails etc. I will try to keep updating this data base but in mere months I will be eighty with all that such implies. Therefore, perhaps others will take over updating this resource in future. Certainly, a comprehensive chapter by Jay Vanini on cultivation would add immensely to its usefulness. It follows that I welcome reports of the errors that I am certain must be many in a work of this size. A major advantage of an E/database is that it can be continually improved. As I write there have only been 18 views of this thread. Facebook surely has many flaws but its outreach is immensely superior. A lot of photos came from Facebook contacts. A thought for the future is that appropriately experienced individuals could concentrate on specific chapters.
  3. 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?
  4. KLU I have since discovered is University Malaysia Herbarium, Kuala Lumpur. It seems it is not digitised.
  5. 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.)
  6. 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.
  7. 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). With illustration and a member of their West New Guinea group. Holotype, Davis et al. 800, K, isotypes BO, L, MAN.

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.

Habitat: Casuarina/ Allocasuarina stand on sloping ground. Habit. Low epiphyte. Semi-circular arrays of entrance holes on tuber. Fruit red, pyrenes 7. http://www.pngplants.org/search.htm Description. Superficially very similar to M. platytyrea but tuber dissections reveal wide, warted chambers surrounded by an open network of smooth chambers similar to those of M. sterrophylla. Tuber pendent, irregularly cylindrical, often curved downwards, 15x8 cm, ridged, coloured dark brown with spines mostly on ridges. Entrance holes in semi-circular arcs; pores present. Stem solitary, unbranched, ascending, tapered over 3-4 cm at apex; clypeoli very prominent, longer than wide, densely rimmed by simple spines to 1 cm long. Leaves clustered at stem apex; fruit red, seed 7-8. Habitat/Range in low positions on She Oak Casuarina/Allocasuarina trees "or montane forest" at 1720-1880 m. (5643-6168 ft.) sympatric with M. sterrophylla.

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.
  15. 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.
