A. What's New in flask.
Encyclia mareae. This Mexican species produces large waxy green flowers with a large trumpet like pure white labellum. It is best grown under intermediate conditions, in a small pot or basket. A well drained media is used, but the plants should not be allowed to dry out while in active growth.
Graphorchis scripta. The Madagascan equivalent of the South American Catasetums is grown as a deciduous plant, a complete dry rest in winter and a repot for spring into a rich media. When the new leads appear, apply lots of water and fertiliser. A small pot or basket and warm to intermediate conditions. (In winter, the dry pseudobulbs can be stored out of the cold until spring.)
Paraphalaenopsis serpentilingua. This terete leafed warm growing Phalaenopsis type has white and red marked flowers.
See December Newsletter for Paraphalaenopsis culture and descriptions.
Sarcanthus pachyphyllus. A Philippines species that was at one time exported from there as Aerides pachyphyllus. A remarkable, attractive plant with thick curved leaves and a panicle of a multitude of small whiite flowers, lip pink purple.
Best grown in a small basket in a well drained media, warm to intermediate conditions and plenty of sunlight.
B. What's ready to replate NOW.
Sobennikoffia humbertiana, a Madagascan angraecoid with large white and green spurred flowers. Best grown in a small basket, intermediate, a somewhat shade dweller that likes very good air movement around the plant. The media needs to be coarse and well drained. Photo: Right
Oncidium stramineum, A Mexicam "mule ear leaf" that grows well on a slab or in a small pot or basket. The flowers are waxy straw coloured, fragrant. Intermediate grower, grow somewhat shady and in the cooler months reduce watering.
Paphinia cristata, A very showy small grower that will exist happily in a small pot or basket in a media that will stay damp but not wet.. Intermediate grower, needs shade and when not in active growth, keep on the dry side, but do not allow to dry completely. Flowers to 7 cm, red with silver stripes.
Plectrelminthus caudatus. An African species with large green and tan spurred flowers. A small basket is best, must have excellent air movement and a shady spot.The media needs to be coarse and well drained.
C. What's new in Plants.
Saccolabium quisumbingii. Seedlings of the Philippines species, dwarf monopodial. Grows under intermediate conditions, well shaded, on a piece of treefern or in a small well drained basket.
Aerides krabiense. Another small growing species, these have developed into flowering size plants in slotted 4" pots. Best grown warm to intermediate, in a well drained media in a basket or slotted pot. Sunlight much as for Dendrobiums etc.
Dendrobium clavator. A species from S E Asia with fleshy, needle like leaves and attractive cream yellow flowers borne enmasse. The flowers have red purple marking on the labellum. Grows best on a mount or in a small well drained pot or basket. Flowering size plants well established on cork.
Dendrobium bigibbum var superbum Alba. This is the Australian Phalaenanthe Dendrobium, well shaped flowers on an arching spike, pure white. Flowering size plants growing well in a small well drained basket.
A few metres off the dirt road, growing under the casuarina trees, were the first Green Hoods I had seen. Small rosettes of
silver green leaves, sitting on the carpet of casuarina needles, their spikes of single flowers erect.
The flowers were neat, red with broad silver stripes, Pterostylis ophioglossa var Collina as I knew it then. A charming
species. No doubt someone has changed its name for some reason by now.
I was a kid then, me and my dad following the old dirt track to Wallaman Falls.
We had stopped at the miners' huts, on top of the Mt Fox range, there to meet an old retired tin miner, Bluey Truscott, nicknamed no doubt after the great Australian fighter pilot. "Plenty of orchids around here, son", old Bluey was glad to advise, and talk, glad of the company.
He was right, there along the road in the rough barked trees were lots of Eria queenslandica, and further along, in the large casuarinas, Cymbidium madidum and Dendrobium fusiforme ( then renamed Dend ruppianum, but it got changed again, it's named now after Mr Jones!!!). Photos below of Dend. ruppianum, epiphytic and lithophytic.
The orchids were abundant in the trees, but unfotunately over the years have proved too tempting to collectors, and now the only remaining plants are high in the tree tops.
This depletion of the natural populations highlights the need to conserve the species by producing seed and encouraging the cultivation of artificially propagated plants of all orchid species.
But the Pterostylis was my interesting find, and my first sight of the genus, several of which I came across over the years until my interest was once again awakened.
Having received requests from overseas for seed of Australian terrestrials, I asked a friend in Herberton, North Queensland to collect a couple of plants and pods of Pterostylis Baptistii from around his barbecue area, where it grew naturally. He did, and in the process sent down plants with pods and tubers, a few plants minus their tubers, and tubers minus their plants.
The seed went to international growers, the plants with tubers and tubers minus plants went into 10 cm pots, with fine bark as the medium. The tuberless plants also went into the same media. All the plants grew, in 10 cm pots full of fine bark, and lots of water.
The next season arrived after a dry dormant rest. With some surprise, I found that the tuberless plants had redeveloped new tubers.
Also, with some surprise I found the Pterostylis grew well and flowered, hooded green flowers tipped orange red.
The secret?? a hint from the collector who told me the plants grew naturally in about 10 cm of leafmould, and the obligatory dry dormant rest, by removing the pots from the bushhouse after the leaves died back. In the dry hot months, the tubers are dormant, and with the start of the annual wet season, new plants begin to appear.
The timing is such that at mid summer, the dormant tubers are repotted and watered, to produce the new plants in autumn.

IMPORTANT NOTE for USA importers.
USDA has, from January 2002, begun to enforce the requirement for a Phytosanitary Certificate for all plant and plant material imports. This is not a new regulation, but the implementation of a rule that has previously not been enforced.
ALL FLASKS imported into USA will now require a Phytosanitary Certificate.
Burleigh Park does provide this Phytosanitary Certificate at cost.
Flasks are still CITES exempt.

A woman walked into the kitchen to find her husband stalking around with a fly swatter.
"What are you doing?" she asked.
"Hunting Flies" He responded.
"Oh!, Killing any?" she asked.
"Yep, three males, two females", he replied.
Intrigued, she asked. "How can you tell?"
He responded, "Three were on a beer can; two were on the phone."
Men are like fine grapes.
They need to be stomped on by women, kept in the dark and matured until such time as they are fit to have dinner with.
As Ogden Nash observed, a successful marriage is one of incompatability.
He has income, she is pattable.
He sat down next to the man at the bar and in a rich Irish brogue, ordered a Guiness.
His neighbour said, “Begorra, you’re from Ireland, so am I, from county Cork”
“What a coincidence, so am I from county Cork, the village of Dumfry.” replied this new found friend.
The other exclaimed, “ Dumfry, begorra, and I went to the Prep school in Dumfry.”
The other said, “ What a an amazing thing, so did I go to that same school.”
At that, the bar tender leaned over and said to his co-worker, “Looks like we are in for a night of it, the Murphy twins are drunk again.”

H. A special note on flasking orchids.
Due to the need for a filtered air vent on flasks to allow exchange of gasses, a reliable air filter medium is needed.
Non absorbant cotton wool allows gas exchange but does not absorb moisture. Thus the air filter will stay dry and prevent
the growth of fungus thru the filter, a common problem with ordinary cotton wool which gets wet, goes mouldy and allows the
mould to grow thru the filter to contaminate the flask.
Non Absorbant Cottonwool NOW AVAILABLE in 375 gram rolls, contact us NOW.
