#48 Orchids in the Barringtons

When I'd spotted the raceme with tiny bumps, which were presumably buds, dangling from an untidy tangle of orchid leaves and twisted roots, I made a mental note to revisit in a few weeks time. So, early yesterday morning, I found myself wandering the walking trail in Barrington Tops National Park, filled with anticipation.

I had been preoccupied, and forgotten to pack a saucepan to boil water for my coffee; I'd forgotten my wallet, and my groundsheet; and I'd forgotten to charge batteries in my camera and phone - but thankfully I remembered my spectacles, because the flowers were so small I couldn't tell whether they were healthy blooms or shrivelled remains of blooms. But, up close, the orchid flowers are little beauties:

Tangle Orchid - Plectorrhiza tridentata

This blog will not have the detail that I was accustomed to providing on my Hunter Valley Backyard Nature blog, as I simply don't have the time for the research at the moment.

Tangle Orchid, Plectorrhiza tridentata, is "an epiphytic orchid forming untidy straggly clumps with long coarse aerial roots and short, flattened stems bearing alternate, well-spaced, narrow, flattened leaves, to 10 cm X 1.5 cm. Pendulous racemes, to 12 cm long, carry 5 to 15 fragrant flowers, each about 0.8 cm across. These flowers are green or brown with a prominent white lip. The large dangling clumps are often supported by very few roots attached to the host, the rest forming tangled groups in the air".

"Flowering period is September to January. Distribution is Qld, NSW and eastern Vic, in gullies, slopes and swamps in humid forests." Ref: A Field Guide to the Native Orchids of Southern Australia, by David and Barbara Jones.

'Tangle' Orchid is an appropriate name

Successful mission! And being short of time, I headed back, admiring the rainforest as I wandered. A flash of purple caught my attention by the track - a Hyacinth Orchid! This was an exciting find for me as I had never seen a Hyacinth Orchid here before.

On closer inspection, something was amiss; the one-metre tall flower spike was detached from the ground. Investigation found a large hole excavated around the base of the leafless plant. Now, I've seen turkey and lyre-bird scratching, and these two native scrub birds were not the diggers of this hole (30 cm deep by 40 cm wide). My educated guess is that the thief was disturbed in the act of pilfering, and fled without the goods.

My battery power held out while I snapped a couple of pictures of the beautiful deep-pink blotched flowers, and then I crawled amongst the foliage and creepy-crawlies and replanted the orchid that still had a short root attached to a horizontal bulb-like structure.

I flicked off a couple of skinny leeches arching up my sleeve, scraped some dirt from my fingernails, and decided I must give this plant a drink. So I walked back to the car for a bottle of water, and went back to finish my gardening; I don't hold much hope for its recovery, though.

Blotched Hyacinth Orchid - Dipodium punctatum



I'm not positive on this ID as there are a few pink Hyacinth Orchids that are similar. The flowering time is right (December to February), but "open forest, woodland and heathy forest" isn't a perfect match for habitat. Nevertheless, there is no denying its beauty.

Disgusting human habits: some people wonder why us humans get locked out of these special places; well when there is an element of humans who ignores safety signs and behaviour signs (no camping, no fires, no collecting of firewood), and shits beside the walking track (leaving a disgusting mess and paper exposed) instead of using the toilet provided 50 metres away, and pilfers protected plants, why the bloody hell wouldn't we all be locked out.

***** ***** *****

The shy paddemelons and the not-so-shy Eastern Yellow Robins were delightful company amongst the ancient rainforest, and temporarily lifted my waning spirit, but it was soon overpowered by the bitter disappointment of the behaviour of unseen fellow humans.

After snacking, I prepared to leave the solitude of this leafy green clearing at the foot of the mountain. There was an odd feeling up my shirt sleeve, and I pulled a bloated leech from the fatty tissue of my upper arm. I hate leeches! I ripped off my t-shirt and gave it a vigorous shake, just in case.

Take heart, Gaye. The orchids will survive long after we - noble or nasty - are all gone.

And don't be too hard on the leeches. Plenty of scientists still sucking up to them for their secret(e)s.

hi Tony,

re the leeches, I guess it's just a girl thing, but at least I am mostly brave enough not to kill them, just flick them off. Even the one that had been feasting on my arm got to live.

Cheers

Hi Gaye
Nice to see you got your Orchids, up at Barrington.
.
I am guessing that you were in the rainforest part, near the old Guest House? Lovely patch of forest.
.
Tangle Orchid was a nice find.
.
I can confirm your ID of the Hyacinth Orchid as D. punctatum. D. roseum is much paler, and D. variegatum has pale ovary and stem behind the flower, with spots on that stem. Your flower has a dark pink ovary and stem, which is clearly visible on the left of your image.
.
See both those species on my post of 8 Jan, for a clear contrast with your lovely flower.
As for the person who dug it up... Less said the better. The books say they are impossible to grow, anyway. You will know they have a relationship with a fungus, which itself grows on the roots of a Eucalypt, so if transplanted, they just die. That's not to mention its illegal to steal from a National Park, etc, etc. Some people drive me mad.
.
You got some nice images, despite having a rough time of it.
.
I hate leeches, too, so its not a girlie thing at all. I hope you don't itch too much. Antihistamines help.
.
Cheers

hi Denis,

thank you so very much for your detailed comment. Looking at your linked post on Hyacinth Orchids, I can see plenty of differences to that of my orchid - these are not so obvious in the small photographs in my reference book.

I knew about the orchid being dependent upon a fungus, but not related to a Eucalypt, so that is fascinating. Thank you for expanding on that. Your photos are superb, and the close-ups of the labellum show beaut detail. It is great to link like-posts in order to offer more information to interested readers (and to this writer). Please do this when you feel inclined.

[Trying to resist the temptation to scratch leech bite as I sit here writing :)]

Kind regards
Gaye

Hi Gaye

I have returned the compliment, and linked my post today about a Tangle-root Orchid to your post here.

Thanks Denis, it is great to have your quality blog with information and excellent close-up photos linked here for the enjoyment of all who pass by.
