WA terrestrial orchids in situ – a four-day field trip to the Mid-west

One of the major attractions for some of the interstate and overseas registrants for the WA Orchid Spectacular was the opportunity to see West Australian terrestrial orchids in their natural setting. Two four-day field trips to the Mid-west were offered to registrants, and were sold out with the maximum number of 20 persons for each signing up. The tours were led by Andrew and Garry respectively, and left Perth at 8.30 on the Monday and Tuesday mornings after WAOS.


Tour 2 group - Photo Chris
The tours included all transport, accommodation and all meals. The first night was spent in Dongara, the second in Kalbarri and the last night back in Dongara. Each day, the groups made 4 or 5 stops to see WA terrestrial orchids in flower, in bud and some that were leaf only.
Andrew and Garry had visited most of the proposed sites the week prior, and had abandoned some planned stops as there were few or no plants in flower, and even fewer in bud that were advanced enough to be open a week later. However, they man-aged to find other locations that provided exactly what the tour participants wanted - lots of orchids in flower!
I was fortunate to be on the second tour which benefited from the regular daily communication between Andrew and Garry about what was in flower and where it was. Our group included three New Zealanders and two Queenslanders, two Victorians all of whom thoroughly enjoyed the experience. The rest of us came from WA.
Over the 4 days, we saw thirty seven different species and four hybrids in flower, many of these in more than one location. Garry was able to identify the species for us, and after we left each location, would tell us what we saw so that those members who wanted to be able to label their photos could do so. Garry has also provided us with maps showing where we stopped each day, and a list of the orchids that were sighted at each location.
For many of us, this field trip was our first opportunity to see the Queen of Sheba in the flesh rather than in pictures. On the last day, at our last stop, this ambition was realised as we sighted two flowering plants of Thelymitra pulcherrima, the Northern Queen of Sheba. We had help from Andrew who marked to location the day before, and a colleague of theirs who sighted the first plant and gave them a GPS location. A member of our group then found another nearby. While it was a quite a walk into the location through soft sand, everyone was
delighted once we got there and found the orchid in flower on a somewhat overcast day.
Andrew's group the previous day had not been so fortunate with the weather, and it needed a little 'hot' Andrew breath for the Northern Queen of Sheba to open up for them. The low scrubby habitat looked most uninviting compared with some areas that we visited, but delivered exactly what we all hoped to see (although there were relatively few plants readily sighted).

So, let's start from the beginning. We left Scarborough a little after 9.00 as the bus had a flat battery (which had to be changed and did not bother us again) and headed up through Wanneroo to Mogumber where we made our first stop where we sighted 7 species in flower, Diuris brumalis, Diuris refractor, Diuris brumalis x Diuris refractor, Pheladenia deformis, Pterostylis orbiculatus, Pterostylis platypetala and Pterostylis brevisepala ms [Pterostylis spp short sepals].
After 45 minutes or so, we travelled further north to Bulbarnett Reserve where we also saw 7 species in flower, Caladenia dundasiae, Caladenia longicauda subsp. (sp Bullbarnett), Diuris refractor, Pheladenia deformis, Pterostylis orbiculatus, Pterostylis platypetala, and Pterostylis scabra. After collecting lunch in Moora, we visited Candy's Reserve where we saw 4 species in flower, Caladenia exilis subsp. vanleeuwenii, Diuris recurva, Pterostylis scitula and Pterostylis scabra.


Then back on the bus before stopping briefly at North West Road where we saw only one species in flower, Diuris tinkerii. Our last stop for the day was Coomaloo just outside Dongara where we saw 3 species in flower, Pheladenia deformis, Pterostylis dilatata and Pterostylis orbiculatus. Our overnight accommodation at Dongara Motel was excellent, with a great meal and comfortable rooms. A few of the orchids we saw on day 1 were:

NOTES FROM YOUR COMMITTEE


1. Thanks to all the helpers at the Spring Show at Cannington on 26-27 August, and to those members that brought plants for our display and the general display.


2. While the number of display plants were down due to season conditions, we managed to put on a creditable display that was attractive to show visitors. The sales table sold $2,975 worth of plants generating commission of $297.50 for the Society


3. Bill Thoms' informal, but informative and challenging presentation was enjoyed by all. As both Bill and Marni Turkel are now members of the Species Society, we want to say big thank to both of them for making the effort to come to WA , to share their knowledge and experience with us, and to bring orchids that we would not otherwise be able to obtain. Hopefully, in the future we will see some of the deflasked species as our monthly plants.


4. If you haven't ordered your new badge yet, please see Mich. The cost for badges with a magnetic clip is $13.50, and with pin is $11.50.

MONTHLY PLANT

Tolumnia varigata

Photo source:

Cost: $5.00

Country of origin: Hispanola and Cuba


Description: Equitant Oncidium species that in its habitat is a twig epiphyte


Difficulty: A relatively easy plant to grow and flower.


The monthly plant for October has been supplied by Tony. They have been grown on from divisions of a plant that he acquired several years ago that is often seen on our display bench.
Tolumnia variegata (Sw.) Braem 1986 is found on the islands of Hispanola and Cuba. It is one of the parents of the many equitant Oncidium hybrids now being sold. W.W. Goodale Moir started breeding these hybrids some 60 years ago and they are now sold worldwide as colourful, compact and free flowering orchids.
Their natural habitat is dry scrub, woodlands and often fence posts at sea level to 700m. The distinct, serrulate (triquetrous) leaves are very distinctive. This species flowers on erect, simple or branched multi-flowered inflorescences up to 80cm tall. It will also flower again on the same inflorescence, so do not cut it once flowering has finished. This species
blooms from Spring to Autumn, with long-lasting, pleasantly fragrant flowers.


For best results, this species should be mounted. Well weathered timber, natural cork, plastic mesh, pond filter mesh or terra cotta pots/slabs are all suitable mounts, with the choice determined by your cultural conditions. This species requires medium light (what you would provide for Cattleya species) and plenty of air movement . In situ, moisture is provided by high humidity, daily rain showers or heavy dews, but due to constant air movement, plants never remain wet for long periods.
This species is particularly susceptible to cotton scale and hard scale. Inadequate air movement accentuates this problem.

Dendrobium farmeri


Dendrochilum latifolium.
Gary Yong Gee says.... Ken and Chris’ Dendrochilum latifolium is Ddc. cobbianum. Ddc. latifolium has a differently shaped lip and much larger floral bracts which cover the ovary and the back of the flower. Ddc. latifolium is just beginning to produce new growths for me and usually blooms in summer and the flowers have a scent like chocolate.
