How it is Done Reg Shooter

There was a very nice benching of orchids at the July meeting. It was interesting to see some very old registered hybrids & some quite recently registered. A lovely large specimen of Dendrobium Ellen was brought in from Murray Bridge. This is the oldest Australian Native Orchid registered in Australia. Way back in 1914 a Mr Wilhelm Schmidt of NSW crossed Den. kingianum with Den. tetragonum. The seed was sown in that year and flowered just over 4 years later in 1928 when he registered it with the RHS. This however was not the first Australian native registered only the first in Australia. Much earlier in 1892 a crossing of Den. speciosum with Den. kingianum was made in England & registered as Den. Specio-kingianum. Today we know it as Den. Delicatum.

Dendrobium Ellen is a very desirable orchid. It is a reliable flowerer and depending on which variety of the parents were used comes in a range of colours from almost pure white through shades of pink to a deep red. It is a cool grower and the South Australian climate seems to suit it. Its requirements are easily met; keep it slightly on the dry side during the cooler months with ample watering when in active growth, & the odd weak application of fertiliser two or three times during this growth period. Given this treatment Den. Ellen will quickly grow into a specimen plant as we saw at the meeting and reward you with a display of flowers that will last for a month or more.

Coming right up to modern times a small plant of Den. Mekong (Molly Dunne x Aussie Victory) registered in 2003 by Down Under Orchids on the bench created a lot of interest. Unlike Den. Ellen which is a primary hybrid, (just having two species in its makeup) Den. Mekong is the result of five generations of hybridising. It has five species in the background, Den. bigibbum, Den. fleckeri, Den. kingianum, Den. speciosum & Den. tetragonum. The plant benched was only small carrying one of creamy flowers with a bright maroon labellum. The shape and substance of this orchid shows lots of promise and it will be interesting to see it when it matures into a full size plant.

Diplodium special field trip to lower South-east July 2007 By R. Bates and Deidre

On the auspicious date of 07/07/07 twelve NOSSA members and pets met at Bangham CP near the Victorian border. Despite 25mm of rain overnight it was sunshine that greeted the campers on the lucky 7th. The photographers among us immediately began capturing flowers of the tall greenhood Bunochilus chlorogrammus while it was Barbie who turned up the first two Diplodium species of the day, in moss under the native pines.

56 Most of us had seen the slender, dark striped D. striatum before but a stumpy, pale green open mouthed species nearby had us baffled. We decided to call it Diplodium species ‘Frogmouth’. There was much discussion about the numerous rosettes of other undescribed greenhoods all about especially in the genera Linguella and Oligochaetochilus.

Our next stop, also in Bangham, revealed a carpet of thousands of Diplodium robustum leaves which yielded just 3 flowers. D. robustum is famous for its poor flowering rate. We were doing well with three different shell greenhoods (Diplodium) before the long drive into Naracoorte for lunch.

In the afternoon we visited a sandy fern gully at Joanna which had lots of tiny purple helmet orchids, Anzybas, surprisingly most in bud. As the flowering season of A. unguiculatus is May-June we thought it possible these were a different taxon. Our leader rushed about looking for shell greenhoods but of course it was the ladies who found them, a delicate little un-named species of the D. striatum complex under pink gum and wattles.

Our final stop for the day was on the track between Dead Mans Swamp NFR and Glenroy CP. The former was set aside to protect Snow Gums which are rare in SA; I’d like to think the latter was set aside for shell orchids.

Once again it was Barbie who found the shell orchids, more D. striatum with one patch having nearly a hundred flowers. Though it was only 4.30 it began to get dark and we headed off to Robe 60km away on the coast and some comfort in caravan parks and motel.

Next morning after refuelling the convoy of 4WD’s and trailers headed down the Nora Creina track toward Beachport and stopped by Lake George at the Big Bend. It was very wet in the soap mallees here (at the Type location for Arachnorchis richardsiorum) but very quickly we turned up three different Diplodium, including a new one for most of us, Diplodium species ‘Nora Creina’ and what a beauty it is with red and green stripes and the lateral coyly thrust forward to give a sneak view inside the hood.

The photographers found these slender delicate flowers hard to resist, trying to capture them with sun shining through the translucent sections. However there was an equally attractive species found by June and DC waiting on a sand dune just 50 metres away. Like many of the species we were finding it is undescribed, but because it tends to be a tall species and has many purple tints it had been given the tag name of Diplodium species ‘Tall purple’, a species we saw on the NOSSA trip to Potters Scrub a year earlier so obviously it is rather widespread along the coast. We searched in vain for another species known to occur here, Diplodium ‘Little Dumpy’, but numerous fallen trees made access difficult.

We moved a few km further south to the Type location for the recently named Bunochilus littoralis. There were thousands of plants most in bud, recognisable still by their large floppy leaves. Once again the photographers were kept busy when flowering plants were located. There were hundreds of leaves of Cyrtostylis robusta (and one flower), Corysanthes despectans, C. incurvus and C. diemenicus and Linguella species ‘Coastal’.

Our lunch stop was at the beautiful bay of islands at Nora Creina and the more adventurous of us headed down a beach littered with purple tentacles of a giant jellyfish and climbed the headland.

57 At this point various members needed to head off, and as our leader was confused about where to go next the remainder headed for the West Avenue Range on the old Kingston – Lucindale railway. As random as this stop may have been it yielded two different Diplodium, a D. aff dolichochilum and more D. ‘Tall purple’, a total of eight shell orchids for the weekend!

Key: B is Bangham, J is Joanna, G is Glenroy, N is Nora Creina area and L is Lucindale road B is buds, F flowers, L leaves, S seed-pods

The success of the trip can be measured by the fact that we saw eight different Diplodium in flower as well as many other species in flower or recently finished. There is no doubt that winter is a good time to look for orchids in South Australia, just a pity the days are so short!

58 FIELD TRIP TO HALE AND WARREN CONSERVATION PARKS: WILLIAMSTOWN JULY 07/07 Margaret Petridis

Despite a week of wet and cold weather and a similar forecast for the day, three adventurous souls – Susan, Andrew and I met at Williamstown for the field trip.

We started at Hale and were rewarded with an abundant array of orchids, mostly on the edge of the track or within a few metres into the bush. Within 10 metres of the start of the track, we saw leaves of Glossodia major, Caladenia/Arachnorchis and greenhood rosettes (most probably either Linguella or Pterostylis species). As we walked up the hill, we found large populations of Acianthus pusillus (with a few flowers), small and large greenhood rosettes (some in bud) and had frequent sitings of Glossodia and ‘Caladenia’ leaves – at least three different species. There were also at least four different species of Thelymitra (leaves only). We found Urochilus sanguineus flowering abundantly all along the path to the lookout and small populations of Diplodium robustum and Diplodium aff. alata also flowering.

Up on the ridge, we found a large population of Corysanthes (Corybas) with some plants just coming into bud. An isolated Corunastylis (Genoplesium) plant with seedpods was found at the side of the path and later a population of six plants was found to the right of the lookout rock. One of these plants had one flower hanging on but the rest were all in seed. Small groups of Microtis leaves were found occasionally along the side of the path.

The most exciting find up near the lookout track turn off were two greenhood plants that appeared to be similar to Bunochilus melagrammus but with a different shaped labellum. This was later identified from our photos by R. Bates as Bunochilus viriosus and was only described early this year by D. Jones.

We had a few light showers in the morning but it was mostly fine and occasionally sunny. After two and a half hours at Hale we went back to Susan’s house to have our lunch on her sunny side verandah.

The weather changed and after lunch it became cold with frequent showers. We bravely headed off to Warren CP but did not find the same abundance there.

The most frequently found orchid was Glossodia (leaves only), followed by3 - 4 varieties of Caladenia. We also

59 found Urochilus sanguineus flowering but they were much smaller specimens than the ones in Hale CP. There were rosettes of at least two other greenhoods, with some in bud. Three different Thelymitra species, and a large population of Corysanthes, with some buds just showing, completed the finds for this area.

After an hour and a half, with increasing rain and reducing temperature, we decided to head back to the cars. We concluded the field trip at 4pm and each headed home.

We all agreed it had been an interesting and enjoyable day and recommend another visit to Hale CP in 6 – 8 weeks to find the various orchids flowering.

The following chart summarises our finds for the day.

The orchid species are named to the best of our ability and with some guesswork for the species we found only in leaf. Actual species will be verified when flowering.
