  1. 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.
  2. 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.
  3. 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.
  4. Hi Jeff, this nursery doesn't have a web site, but I can attach an old catalogue.Microsoft Word - Email Cat2013.pdf
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. 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.
  13. 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.
