[OGD] Limestone or Granite
Phil, You said: >Interestingly, Manolo in a conversation said that P. besseae also grew over limestone. Do any OGDers have comments about that? Yes, I'd say Sandra is correct.. Phragmipedium besseae is known to grow on steep granite rock cliffs at about 1300 m.a.s.l. There may be exceptions that experts know about, I have no knowledge of it, for I acknowledge that I am not an expert. All the habitat pictures I have seen of Phragmipedium besseae have a black granite background that brings out the red color beautifully. I am certain you have seen this too. Phragmipedium kovachii does grows on limestone rock at about 1900 m.a.s.l. >It was noted that he obtained flasks from some other vendors (there was a lot of international flask interchanges tookplace, presumably swaps), all of South American species. Sort of like sending ice to Alaska (for US readers) or coals to Newcastle (for poms). Yes, I agree, Manolo purchasing Peruvian Orchid Species Flasks in Australia sounds about as strange as Australia selling ice to Alaska. Perhaps it is connected with the following information I received from Peru a few weeks ago: On July 13 2006, a Peruvian Government document referred to as Decreto Supremo No. 043-2006-AG announced that Peruvian Orchid Nurseries may no longer export collected orchids. From now on all orchids exported must have been propagated in-vitro. It has orchid nursery owners in an uproar, for most of them do not have any stock propagated in-vitro and many do not even have a laboratory.Some have operated this way for decades.. Nursery owners tell me that there is no lead in time given, which you and I know should be 7 years minimum, if your intend is not to destroy the orchid industry of your country. They all blame a given orchid nursery for suggesting the new laws to the government and conveniently forgetting to tell them to give a lead in time. That nursery started a lab a few years ago, is claiming to have propagated large quantities of flasks of different species, but the victims of this new law claim they purchased them from other orchid laboratories. I do see court cases in the near future. Will the government delay the date this law goes into effect??? I have no idea. peter ___ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com

[OGD] Phrag besseae in situ
Phil, I've seen P besseae growing in Ecuador at ~6000 ft on a northeast-facing granite cliff with water running continuously down the cliff face. They were also growing at the base of the cliff in amongst the weeds, grasses & rocks. Sandy Hardy Savannah, GA Would you like to share my orchid photos?

What is with the '(?)' in the name 'Orchid fleck (?) rhabdovirus'? And I see that this is the only virus listed for Paphs in the site given above. I had 2 Paphs turn up positive on the single well ELISA test for CMV. My assumption is that the web site given above is not very complete, in fact, very incomplete would be a better description. I think that this fact should be pointed out to those who might peruse this page. http://image.fs.uidaho.edu/vide/famly094.htm Do you think maybe I should I have had these plants retested with the double well test? Is there a lab doing ELISA testing for Orchid fleck (?) rhabdovirus?

[OGD] industry [Philippines]
"the world's flower market worth US$97.2 billion. ... Kelvin Neil B. Manubay, president of the Philippine Orchid Society (POS)... of the amount the country gets... a share of about 0.02 per cent annually. ... Manubay noted that 487 foreigners from South Korea, Taiwan and Thailand have visited the Philippines to look at the country's conservation of orchids and its various species. However, the foreign experts, Manubay said, still saw the orchid industry in the Philippines as not being supported enough by the government. The POS president believes that the country will be able to penetrate the world's multibillion-dollar flower industry if the government will support the industry, given that the Philippines has shown its orchids abroad, particularly in Singapore and Japan. Manubay is also asking the government to reconsider the restrictions [???] in the orchid industry and the flower industry as a whole to facilitate its growth."

Re: [OGD] kovachii
I don't quite understand what all the fuss is about. It is apparent to me that Peter, in Canada and vendor for one Peruvian source (CJM), has said he will not sell Pk seedlings until they are "compot size." Barbara's source is apparently Jerry Fischer and Chuck Acker, who purchased their Pk flasks from the other Peruvian source (PeruFlora), who, I understand, made them sign an agreement to not sell their seedlings prior to a certain time, whereas CJM made no such requirement. So speaking as an outsider to the discourse below, here are my observations: --I don't see any inuendoes in Peter's postings -- he is up-front in what he says. Peter is not yet selling Pk, but he is taking pre- orders as are the US vendors of PeruFlora plants. --Barbara seems to be saying that no one should be selling Pk flasks yet. Since she is in the US, and I know of only one place that is currently selling them, she must be talking about Piping Rock Orchids. Note that Piping Rock is selling flasks, not Pk seedlings out of flask as yet. --I suspect were it not for the agreement signed, Orchids Limited and Chuck Ackers would also be selling their Pk now. I could, of course, be wrong. --Unlike Barbara, I have no problem with Piping Rock selling their Pk flasks and hybrid seedlings now. I purchased my Pk flask from Piping Rock Orchids, whose Peruvian source is also CJM. The seedlings in my flask were beginning to touch the top of the flask when I put them into compot, where they were doing fine until I made a mistake and sprayed them with Physan. I lost a few, but the others seem to be recovering. (I'm keeping my fingers crossed.) I'm also finding they prefer temperatures cooler than 72-73ºF, which has been difficult for me to achieve this summer. Speaking for myself only, I am happy that I purchased a Pk flask. While it is true that there is little information about the specifics of growing them, I'm glad to be part of the experiment. Time will tell whether any "rumors" are true about whether any Pk flasks/seedlings are actually not Pk. The US players here, the Fischers, Chuck Ackers, Glen Decker... are all excellent growers. I think they all know that honesty is the best policy. There is too much at stake to be otherwise. Cover-ups usually don't work in the long term.

[OGD] Triphora trianthophora var. texensis / Texas [US]
" "Pike's three-birds orchid,"... newly discovered East Texas blossom named for a Lufkin wildlife biologist with Texas Parks and Wildlife who discovered it last summer. It was... the crested coral root [Hexalectris spicata], that drew Dick Pike to the depths of the Davy Crockett National Forest... Aug. 26, 2005, when... a bed of snow-white blossoms with delicate cerise and lime edges caught his eye. "... it has very small above-ground stems appearing only a few days a year," said Pike... "... it was the first Triphora found in Texas," Pike said. ... Paul Brown with the University of Florida Herbarium declared Pike's discovery a new variety. ... Pike's first observation included 33 plants along a 100-foot-long slope beneath a heavily shaded canopy of 150-200 year-old mixed hardwoods and pines. Pike's field notes and pictures and Brown's botanical/historical research culminated in their article, published Aug. 15 in the North American Native Orchid Journal. ... "Wild Orchids of Texas: a Field Guide," ... which will include Pike's newly classified variety, is expected next year. ... Adhering to scientific classification protocol, Pike's new variety refers to its location, Triphora Trianthophora Var. Texensis... Brown gave Pike's Texas orchid two common names which will be left to wildflower enthusiasts and writers to favor and promote one over the other Pike's three birds orchid or Texas three birds orchid."

[OGD] LEDs and more virus stuff
P E Dean <[EMAIL PROTECTED]> queried thusly: Anyone else growing orchids under LEDs? I sure would like to hear from anyone who is. Or to find books or websites with specific info, sources for LED arrays with particular wavelengths, etc. I've been experimenting with some LED Grow-Master lights: http://www.led-grow-master.com/ (Disclaimer: the company sold them to me at distributor's prices to determine their utility in growing orchids.) I have been growing orchids in sterile culture under these light sources, as well as potted orchids. They seem to do the job for growing orchids in flask; however, at this stage, they are largely chemotrophic (living on the salts and sugars in the substrate), and even at very low levels of illumination they do surprisingly well. I should think that LED illumination may one day be competitive with fluorescent lights. Until such time that they can come down to the price of a $20 reflector and 2 x $4 bulbs, they are not a replacement. I wonder about operating costs making up for it. At perhaps 5 watts total (for bulbs and a DC transformer) versus, say, 32 watts of power from one T8 tube (a very rough equivalent), you're spending an extra 27 watts of power. Used for 12 hours a day, that's 324 watt-hours, or about 3.24 cents per day at 10 cents per KWh. Over the course of a year, that works out to $11.83. A commercial LED unit at, say, $100 versus a fluorescent unit at $12 (half of a 2-tube array) would take 7.43 years to pay for itself. That doesn't include the cost of changing bulbs every couple of years, and it's too late at night for me to do the math on that. It may compare more favorably with metal halide, but I've only used MH once or twice, and that was somebody else's money, not mine, so I can't remember the math. LEDs do have the benefit of not having to remove quite so much heat when illuminated. It may sound insignificant, but when I ran a growth chamber with 14 kilowatts of fluorescent illumination, things got pretty far out of parameters when the vent system went down. "marianne haeck" <[EMAIL PROTECTED]> spaketh thusly: Hello, someone told me that it is impossible for Bulbophyllum to have virus, is this true? Someone is gravely misinformed. Incidentally- someone asked about paphs and virus. From: http://image.fs.uidaho.edu/vide/descr541.htm Orchid fleck (?) rhabdovirus Host species include: Coelogyne spp., Dendrobium spp. (and hybrids), Miltonia spp., Odontoglossum spp., Oncidium spp. and Paphiopedilum spp. - chlorotic areas often with necrotic centres or rings. See the URL for a full list of susceptible species. The webpage comes with a list of ten scientific references, at least nine of which are from refereed publications. Or, as the doctoral student once screamed at me: "My plants are not virused!" "Oh! You've had them indexed, then." "What's indexing?" That was the first sign of trouble, right there. The second was when she insisted her plants would "have spots" if they were infected.
