  1. Hi Dema, Pm me and I will get that organised for you. Robert.
  2. Its mid-winter here in SE Queensland and my ant plants have really slowed down, but several species are still producing fruit. Here is a photo of another of my young H.ferrugineum that has just ripened its first fruit. It has a caudex dia.of 65mm (2.5") and was re-potted from a 50mm (2") tube to a 100mm (4") pot 18 months ago.
  3. I would like to take this opportunity to thank all the forum members who shared their experiences of growing this species both good and bad, as it was this information that ultimately led to my success in growing and fruiting this lovely species. This is the best thing about this forum, the sharing of knowledge of which there is a wealth of amongst its members. Below is a picture of the entire plant which is in desperate need of re-potting, this will be done after a few fruit have been harvested and have started to germinate, I do not want to take the risk of the plant possibly dropping immature fruit as it is the only plant I have, and only one of five in the country.
  4. Fruit at last, 27 months after planting my first ever H.puffii seed the plant has matured its first fruit. It has just over a dozen fruit on it and the first one has ripened in the first month of our winter here in the southern hemisphere, so Frank the plant seems to be following the same fruiting cycle as plants in the Northern hemisphere.
  5. Hi Jeff, this nursery doesn't have a web site, but I can attach an old catalogue.Microsoft Word - Email Cat2013.pdf
  6. The three smaller and smooth light green leaves near the top right of the photo are from a neighbouring plant that grew across and attached to this mount, they are from a D.platyphylla.
  7. Hi Frank, these poles are old recycled ones probably from the pre-treatment days and have been weathering in the elements for decades. IML stands for Iris Marie Liddle, the wife of the late David Liddle who was an Australian authority on Hoyas and Dischidias, he used his wife's initials followed by numbers for his vast collection. You can find specimens in nearly any Botanical garden or Herbarium worldwide using his numbering system, his collection of these plants was and probably still is one of the largest in the world. David used to travel through Asia, New Guinea and the south west Pacific Islands looking for new species and forms, his wife still runs the nursery in Mareebe, North Queensland.
  8. My method of growing the imbricate forms of Dischidia is to have them both potted and mounted. The young plant is started in a pot and when the stems start growing over the rim, the pot is mounted onto a hardwood fitch ( the one shown is from an old telegraph pole) and the stems trained onto the timber. The advantage with this system is that watering is not as critical as in a plant that is just mounted, with this system the plant can always draw some moisture from the pot. This method is not that different to how plants grow in the wild, if a stem in a wild plant runs into a litter collecting fern for example it will infiltrate the moist litter and concentrate a whole lot of roots in this area to exploit the extra moisture and nutrients.
  9. I have four forms of M. tuberosa - Cape York, Dahlii, Armata and one labelled 'Bogor Gardens'. Can anyone tell me anything about the Bogor Gardens form, it looks very similar to the Armata form, only the slightest difference in leaf width as far as I can see.

    Myrmecodia tuberosa 'Bogor Gardens'

    There is another "armata" Malaysia form behind it to the left of screen, just in front of a large H.ferrugineum. the plant to its right is a M.beccarii "Southern spineless ferm" from Cardwell.

    Myrmecodia tuberosa 'Bogor Gardens'

    As my two forms of M.tuberosa "armata" - Bogor Gardens and Malaysia are getting older and larger I am starting to see some difference in the shapes of the caudex. Here is a photo of one of my plants from Malaysia.

    Myrmecodia tuberosa "dahlii" New Britain Island.

    A fairly mature cultivated M.tuberosa "dahlii" looking very happy mid-way through the Wet season in South East Queensland, freshly re-potted and sitting in a brand new shadehouse.

    Variation in M. platytyrea sub.antoinii "Southern form"

    Hi Jay, These plants are found over a range of altitudes from steamy lowland gorges to up around mountain tops, this would explain their ability to grow warm or fairly cool. I have noticed this with M.tuberosa "dahlii" which is also found over a wide range of altitudes from sea level to 1,000M. These southern plants also look a bit different from the Cape York forms as well, and many think it would not be surprising if they were split from them if any botanical work was ever done on these plants. I have never had seedling mortality in the winter, but put that down to the fact that I grow my plants in a bark, charcoal and perlite mix that dries out quicker than sphagnum and so the roots and bottom of the caudex are not always cool and wet, also careful watering in the winter. I totally agree about the light, I grow my plants hung up high under about 60% shadecloth, the brighter the light within reason the faster they grow.
  14. This is the form of this Australian species that is the most commonly encountered in cultivation, and normally called the "Mossman form" as this is the easiest place to see them growing in the wild at Mossman Gorge. In reality they occur in a much greater area in this northern part of the Wet Tropics, with isolated population in other small National Parks in the area and growing high up in trees even on Mountain tops such as Mt.Lewis. Many growers have found that they grow happily at fairly cool temperatures in highland conditions as well as lowland conditions, one Aussie forum member grows them very well in a near coastal area in Central NSW at latitude 33oS whithout artificial heat. At this stage I have plants sourced from two different Nurserys and one from a private collector here in Australia, two of these forms are very different from each other and the third are still juveniles so will have to wait a bit longer to see.

    Variation in M. platytyrea sub.antoinii "Southern form"

    Seedlings from both these plants are fairly uniform and retain the features of their parent plant. Seedlings of the larger plant with the tapered caudex were originally purchased as M.beccarii, but this was proven incorrect when they ripened their first pale orange fruit. This form is very fast growing and vigorous compared to the form to its right, not to say that the squat form is slow growing, the tapered form is just very fast. The following photo shows the uniformity of the seedlings.

    Jeff, I would suspect insufficient lighting could be the problem, especially if heating and ventilation have remained the same as always. Light bulbs loose output as they get old and have to be replaced, if you use natural light, panels can become more opaque or stained over time and drop the amount of light getting to your plants. If your seedlings are leaning towards any external source of light this could very well be your problem.
  17. Earlier today I went to visit a good friend of mine who grows many different types of plants including ant plants. I showed him a list of Dischidias I am growing and he asked if I could identify a plant that a friend had recently collected on Cape York Peninsular. As soon as I saw the plant I knew it was either a new species or a distribution extension of an already known species not previously recorded from Australia. This plant looks very much like Dischidia albida from pictures I have seen , as soon as Ashley Field gets back from his field trip I will send him a picture of this plant. My good friend gave me the cutting I used for the following picture, he will now try to get a more specific collection site. Cutting of the unknown Cape York Dischidia.

    Murmecodia tuberosa "papuana" two cultivated forns.

    The reason I have pictured six plants of the Lockhart River form is to show the fairly uniform rate of growth among the plants, but more importantly the variation within a form. The plant second from the left has developed an elongate tuber and the plant on the far right has naturally developed two main stems, all these plants have been grown under the same conditions from germination.
  19. Six young sibling plants of M.tuberosa "papuana" Lockhart River form, which are virtually the same as the Iron Range form as the Lockhart River area is on the eastern border of Iron Range NP. All these young plants are starting to flower and growth for a Myrmecodia has been fairly rapid. Fellow member Rita Kupke germinated these plants and potted them into 50mm (2") pots from a community tray in March 2015, I received the plants in March 2016 and three months later (June) potted them into 100mm (4") pots. On average Rita's seedlings spend 20 weeks in community trays before being big enough to be individually potted, this would make these plants just under two and a half years old. The fairly mature individual plant is a McIlwraith form of "papuana" and has a very interestingly shaped caudex, it produces fruit right through the winter here and with good feeding produces 7 or 8 seed per fruit. Of all the different sub-species and forms of M.tuberosa that I grow, this plant and its seedling are the slowest growing by a large margin, weather other plants of this form are as slow I cannot say at this stage.

    Myrmecodia tuberosa 'Bogor Gardens'

    Hi Jay I have two of these plants and two "armatas" from Malaysia, I have inspected these plants side by side and the only difference I could find was that one form had marginally narrower leaves. At this stage it could just be seedling variation, once I grow up about a dozen seedlings of each and compare them I would not take much notice of this.

    Myrmecodia tuberosa 'Bogor Gardens'

    This is the plant labelled M.tuberosa "Bogor Gardens", the original material came from a grower in Singapore.
  22. Hi Frank, I am growing this species in the southern hemisphere at 28o south in S.E.Queensland. The first small flowering on a 19 month old seedling occurred between the 20th to the 29th of October, which is our mid spring. No leaves were shed though until a misshap with a neem oil spray a week or so later followed by a fairly hot day caused about 60-70% of the leaves and its first three fruit to fall off. I was NOT happy! But the plant soon started to push out new growth and yesterday the first flower from a new bigger batch of flower buds opened, we are in the last month of summer here with about 22oC av.min. to 32oC av. max. for the last month. So at this stage not following main flowering times as in the northern hemisphere , or it may just be sporadic flowering and the plant might settle down to a main flowering period as it matures. This plant is grown in natural sunlight under shadecloth.

    Fantastic news Frank, I agree with everything Jay has said in the previous post. I look forward to contributing many new articles in the very near future as my new shadehouse is nearing completion and I will have the time and space to photograph plants and share information with members. Cheers, Robert
