There is nothing ‘common’ about the beautiful ground orchid Calanthe triplicata currently flowering along some of the rainforest walking tracks around Paluma. Flowering specimens have recently been observed near the track to McClelland’s Lookout (off the Loop Road) and along the H-Track.
This evergreen terrestrial orchid generally grows in clumps from fleshy pseudobulbs. The plant has dark-green lance-shaped leaves with prominent parallel leaf veins. It can grown to 1 metre tall, but all of the specimens observed at Paluma are smaller, between 30 to 40 cm in height. The white flowers are borne on erect racemes at the top of the flowering stem. Flowering occurs from October to February.
The Christmas Orchid occurs in Cape York Peninsula and North East Queensland, usually in mountain rainforest at high altitude from about 700 metres to 1250 metres.
I am sure all of us have had a good feed of tropical fruit over the Christmas-New Year period but I doubt that this included any of the fruit which is currently scattered along our local walking tracks. This food is vitally important to local birds and mammals as well as insects, and some of it is edible and would have been highly valued by traditional owners of the forests. During two walks over the holidays (one by my daughter Carla and her partner Michael out behind the dam just after Christmas, and the other by me along the H-track this Sunday past) it was possible to accumulate a pretty diverse and colourful assortment of fruit. I thought I would share the photos since the colours and shapes are are visually stunning.

Since retiring I have been sporadically collecting fruit during my walks and looking them up in the rainforest fruit “Bible”1. This has enabled me to make a guess at the names of around a dozen of what I reckon is 20 different species between the two platters displayed here. I know that some of these are edible, but others may not be so please do not experiment with any fruit you find in the forest unless you are absolutely sure of your identification and your knowledge of edibility.
Here is the list of trees whose fruit I have tentatively identified in the photos.
Paperbark Satinash (Syzygium paparaceum)
Silver Ash (Flindersia bourjotiana)
Grey Carrabeen (Sloanea mcbrydei)
Small leaved Fig (Ficus obliqua) a strangler fig
Silky Tamarind (Guioa lasionerua)
Hickory boxwood (Planchonella euphlebia)
Synima (Synima cordierorum)
Bleeding Heart (Homalanthus novo-guineensis)
Powderpuff Lilli Pilly (Syzygium wilsonii)
Quandong (Elaeocarpus sp – foveolatus?)
Black Pine (Prumnopitys amara)
Jitta (Halfordia kendack)
Cinnamon Laurel (Cryptocarpa densiflora)
If anyone has any other names to suggest please leave a comment!

Over many years Don Battersby has been vigilant in recording the annual rainfall statistics at his property on Hussey Road on the western outskirts of Paluma Village.
Don has kindly contributed the following rainfall statistics for Hussey Road for 2019. The total rainfall recorded by Don for 2019 was 4205.5 mm with rain falling on 99 days of the year.
The stand-out months for rainfall were January and February with a total of 3069 mm of rain falling in these two months (equivalent to 73% of the total rainfall for 2019). In the latter part of 2019, the stand-out month for the lack of rainfall was September with not a drop of rain recorded at Hussey Road!
Are there other rainfall recordings for Paluma and surrounds?. If you have been recording rainfall at your property we would love to have your statistics!

It is certainly the season for the Northern Leaf-Tailed Gecko (Saltuarius cornutus) at Paluma.
My previous posts during December 2019 have reported the movements of a rather superb specimen at the eastern end of the village between the residences of 13 and 17 Mount Spec Road.
Linda Venn has now contributed a photograph of her resident Gecko, also at the eastern end of the village. Linda reports that this specimen has been sighted regularly at her home over a period of some years. She describes this individual as about 7 to 8 inches in length (or about 20 cm).
Don Battersby says that he has numerous specimens living at this property on Hussey Road. They favour the shed walls and appear nightly to forage for food.
As mentioned by Michele a couple of days ago, there is currently a rather spectacular orchid flowering on the H-Track. It is the Giant Climbing Orchid (Pseudovanilla foliata) Apart from its beautiful flowers (in copious quantity), this orchid is also special in that it has no leaves. It is one of several species of saprophytic orchid that derives its food from rotting wood rather than from photosynthesis. This particular species is not often seen around Paluma since it spends most of its life as an inconspicuous tangle of stems climbing up dead trees – it flowers only briefly. Once the logs and dead trees that it feeds off have fully rotted away it dies off. Wilfred Karnoll informs me that after cyclone Yasi these orchids made a brief appearance in a few locations along the walking tracks near the village.
Flowers are produced in great numbers for a limited period. they have a faint but pleasant scent.
The roots penetrate rotting wood
While this orchid has green stems and may be able to make a small amount of food for itself, it is unlikely to able to grow and produce masses of flowers on this energy source alone. Most saprophytic orchid lack any green colour, and thus do not need (and cannot use) sunlight to obtain food. One group of these orchids has completely forsaken sunlight and spends its entire life, growing, flowering and fruiting underground – never seeing the light of day!
Technically saprophytic orchids do not directly feed off decaying wood and vegetation, but derive their food from a close symbiotic relationship with fungi that do all the hard work of breaking down the fairly indigestible wood and then provide it directly to the roots of the orchid. Whether this is a mutualistic relationship (with both obtaining benefit from the exchange) or a parasitic one (with the fungi being robbed of fuel it would prefer to use for its own growth) is not fully understood. So far, research on this matter appears to have failed to show any clear benefit to the fungi.
After reading a bit more about orchids on the web I discovered that the relationship between fungi and orchids is widespread and devilishly complex. Virtually all orchids rely on fungi for seed germination. Orchids produce seeds that are microscopic in size (they make up for this by producing prodigious numbers in each seed capsule). These seeds are so small that they do not have the energy reserves that all other seeds use to fuel the cell division needed for germination and subsequent growth of the first green leaves that will manufacture new fuel from photosynthesis. These tiny seeds rely entirely on fungi for that germination energy. Some orchids have been shown to have an ongoing obligate relationship with fungi, while others shrug off this reliance once fully developed. A further twist in the orchid-fungi story occurs in some species, where the fungi that the orchid derives its food from, is itself deriving its fuel from the roots of certain tree species. Thus we have sunlight being turned into food high up in the forest canopy and then being transferred down to the forest floor, into fungi and then into the saprophytic orchid!
This weird flower is blooming in my garden, in a semi-shaded spot near the letter box. The bat flower is a member of the yam family. Species of Tacca are found in tropical regions of South America, Africa, Australia and South East Asia. Difficult to see in my photo is the cluster of tiny, dark flowers at the centre. The ‘whiskers’ are between 40 cm and 60 cm long.
On Saturday afternoon (28 December 2019) we decided to take a stroll along Paluma’s H-Track. The main impetus for the walk was a tip-off from Jan Cooke that the giant climbing orchid, the ‘Pseudo Vanilla Orchid’ (Pseudovanilla foliata) was in flower along the track. Having never seen this orchid in bloom I was keen to observe and photograph it.
The Pseudo Vanilla Orchid in full bloom.
More information and photographs of this spectacular and unique orchid will appear in a future post by Jamie Oliver.
We started our walk at the eastern end of the H-Track off Lennox Crescent. After some showers of rain in recent days the rainforest appears refreshed and revitalised after the long dry spell. Fungi of several colours, shapes and sizes has sprung from decaying wood along the track.

It wasn’t long before we encountered a sizeable red-bellied black snake, actively foraging for food amongst the leaf litter. Upon detecting our presence it appeared quite agitated and retreated into a hole at the base of the buttress roots of a large tree. It immediately reappeared, head first, raised and in defensive mode. We quickly moved on, leaving it to its foraging.
My very blurry and unfocused photo of the red-bellied black snake. I have to admit to being more ‘focused’ on the movements of this snake, than on focusing the camera!
The walking track and surrounding forest floor is littered with numerous fruits and flowers at the present time. We observed the fruit of quandongs (Elaeocarpus sp.) and the brilliant purple fruits of the Paperbark Satinash (Syzygium papyraceum). Many of these fruits showed the distinctive nibble marks of rainforest marsupials and birds.

There are some spectacular trees to see along the H-Track including many large specimens with distinctive buttress roots. There are also some splendid climbing vines weaving their way high into the rainforest canopy.
A stroll along the H-Track is always a pleasure with so much to see and absorb. Take the time for a wander along this short rainforest track and you are sure to be rewarded with many interesting sights, sounds and the wonders of the tropical rainforest. The bird calls alone are worth taking the walk! During our stroll we had the pleasure of listening in on numerous conversations high in the canopy, courtesy of the shrike thrushes, cat birds and whip birds.

This young Lily is almost 1 metre tall and boasting a 24 cm heavenly scented bloom. When she matures, she will produce 4-6 flowers on a single stem. Loved by the bees and butterflies, this beauty has won the prestigious ‘Award of Garden Merit ‘of the Royal Horticulture Society in 1993 for best White Oriental Lily ever. Reliable and easy to grow in any moist soil with good drainage. I’m hoping my thumbs stay green enough to bring her to full maturity and be rewarded with multiple blooms every Christmas.
The Northern Leaf-Tailed Gecko of my previous posts (2 December and 17 December) has been conspicuously absent from its usual home (my garage and laundry) over recent days. On Saturday, we discovered why…….
The Gecko has a second home and now resides at Colwyn’s place, two doors down from my home. We are certain it is the same specimen, given its large size of some 20cm or more. Colwyn checked its measurements just to make sure! Its statistics confirm it is very likely to be the same individual. It is now a different colour being a slightly darker shade of grey-brown, compared with the lighter-brown, coppery colour it had at my place. It appears the Gecko has moved on……!

Have you seen the beautiful Calliandra sp. currently flowering in Linda and Bill Venn’s garden along the eastern end of Mount Spec Road? It’s hard to miss as the shrub is fully laden with pink and white blossoms. The flowers seemed to appear overnight and they opened all at once, making a superb display. The shrub is literally a hive of activity with many bees, both native and exotic species, as well as butterflies busily feeding on the nectar from the blooms. Bill and Linda tell me that the shrub is a miniature variety of Calliandra.
Calliandra, also known by the common name of ‘Powder Puff’ is a genus of tropical plants native to South America. They grow and flower best if they are in full sun. Their oblong shaped leaves fold up ‘to sleep’ at night. They thrive in moist, well-drained soil.
The Venn’s Calliandra has flowered just in time for Christmas, with its brilliant candy-coloured flowers . Who needs an ordinary Christmas tree when you can have a Christmas Calliandra!
