I will start this long post addressing the increasingly overt accusations that Orchid Inn has deliberately sold mislabeled seedlings of Paphiopedilum rothschildianum on a grand scale. I have known Sam for over 20 years, during which time I have grown out hundreds of his flasks. Now that Sam is retiring, I am in the process of taking several deliveries comprising a significant portion of his remaining stock- including Paph. rothschildianum, and so I have both a personal and financial interest in addressing this accusation, along with a strong desire to defend the reputation of a dear friend and great ambassador for Paphiopedilums. I regret to see I stand nearly alone in speaking up for him here.
I have accepted the challenge laid down in this thread and the other where rothschildianum is currently being discussed. I have gone to Facebook and registered with two of the largest Paph communities and conducted extensive searches of their content with search terms like “Orchid Inn”, “Sam” and ‘rothschildianum”.
There were a couple of posts on problems with authentic rothschildianum from Select Orchids (a commercial entity owned by the accuser) but they were not specific to OI as are some posts here. Beyond that I found nothing- not a single assertion of Orchid Inn selling misidentified or substandard plants. And so, I find no merit in the suggestions that FB is a place to find a large number of disgruntled OI customers. In fact, quite the opposite is true.
On the question of breeding and the notion several seem to support here that the majority- or more- of a population of seedlings should meet or exceed the quality of the parents, that is just not how it works in my broad experience- and rothschildianum in particular deserves a detailed discussion on this point.
When Jack and Val Tonkin made their landmark sib cross of ‘Borneo’ x ‘Charles Edward’ (aka ‘Charles E’) in the late 1970s, rothschildianum became widely available to the general public for the first time ever.
Per an AOS Bulletin Article published in January 1990, about 2,500 plants were produced, and, it was estimated at least 50% of the plants that had flowered were an improvement over the parents with regards to “flower quality, growth habit, and floriferousness.” The article further noted that Tonkin had 238 of the plants in bloom at the time and had received 28 quality awards so far on rothschildianum. Additionally, the article noted that there had been very few successful intraspecific crosses of rothschildianum to date, in part due to inbreeding and cited one particular cross where a first bloom seedling presented at an AOS show had flowered after 15 years on a two growth plant with one deformed blossom. [AOS Bulletin, January 1990, “Stop Buying Wild Collected Plants”, Griesbach, R.J.
Per OrchidPro, the Tonkins have a total of 31 AOS Awards for rothschildianum, including the original AM for “Borneo” and its CCM and later FCC upgrade. I found two awards that were granted subsequent to that 1990 article- so by the time of the article cited above, the Tonkins had received almost all of the awards they were going to get for that cross. There are in older records a number of unidentified exhibitors, so it is possible they had other awards my search did not capture. In terms of plant count- when I bought one in 1995, Val Tonkin told me she still had a “greenhouse full” and general rumor at the time was that there were still several hundred plants which had never flowered.
Point being, as of 1990 in the 30 years since rothschildianum was rediscovered, you had only one highly successful sibling cross known to the general public (I am not aware of others- but much goes on behind closed doors and always has) out of a great many failed attempts, and as of the 11th anniversary of that cross you had about 1% receiving quality awards, and I would estimate one half of the plants still having never flowered, with rapidly diminishing returns over time. Assuming my estimate is accurate- the over 50% success rate in improvements over the parents translates into over 25% of the total population, again assuming- and I think reasonably- rapidly diminishing returns on the back half of the population, much or most of which never flowered.
When you breed two plants, you are- hopefully- selecting plants that performed in the top 5% of the total population or have one or two specific features that are so amazing that you want to perpetuate them. By nature most of the resulting progeny will be lesser than their parents. This is how it works. If it is a good cross with parents that have proven compatible for the kind of results you want, then over time you expect the plants to be better on average if you do sib crosses of top examples- but a cross that generates a significant number of plants- such as Phal. Orchid World- which are a marked improvement over the parents is very rare.
And so yes, I expect that most rothschildianum seedlings are not going to be as good as their parents. And only a fraction will strongly take the best traits of their parents and become similarly awardable.
I have attached two scientific articles on rothschildianum to this message that are highly informative about the species itself and its fascinating history and habitat. The first – Ecology of Paphiopedilum rothschildianum – is a fascinating read I think all of you will enjoy immensely. It tells the remarkable tale of field research into rothschildianum’s habitat- a habitat that actually evolves as the plants age and ultimately provides for their demise. The article is relevant to this discussion for two reasons. First, it offers a plausible reason for there being 3 distinct and separate habitats for rothschildianum with very distinct gene pools and characteristics. Second, you will see a photo of a plant flowering in the wild with somewhat downswept petals- a phenomenon often blamed on some stonei in the parentage when present in cultivation (the Sunlight Sky Roth hybrid), when in fact it is a characteristic of some roths. I absolutely believe Sunlight Sky Roth has been sold as rothschildianum. But you can’t just see downswept petals and assume the plant is not rothschildianum.
The second article is highly technical, well beyond my means in many respects, but a good article on the study of rothschildianum genetics. I present it here to evidence the very real fact the three separate populations of rothschildianum documented in Kinabalu National Park (Sabah, Malaysia, Borneo) have very distinct gene pools that have developed largely in isolation. This explains the complication in identifying pure rothschildianum in cultivation because the populations even differ in the appearance of the leaves. And given the relatively short time rothschildianum has been in cultivation AND heavily intra-specifically bred, I imagine there are precious few people on the planet who have the hands-on and eyes-on knowledge to really begin to understand these things and make good identifications.
I think the 3 populations also could help explain why the performance of rothschildianum siblings has yielded more deformed and sub-par flowers with some crosses over time. Simply put- lacking a really detailed knowledge of the origins of all parents, it is hard to know the degree to which the 3 gene pools are being cross-bred versus 1 pool being overly dominant and creating more in-breeding difficulties. Outside of awarded progeny of Borneo x Charles E and a handful of collected plants, are there even any great breeding plants still in existence? Inbreeding is a real problem here.
Further complicating matters is the incredible dominance rothschildianum has over almost every other species it is crossed with. That makes it much easier to inject something else somewhere in a long breeding line and get the benefit of some much needed fresh genetics while leaving little trace of the deception. Sunlight Sky Roth is a great example.
@Roth – based on my knowledge of you and your experience, I believe you are one of those very few people who really does understand rothschildianum. Despite my rebuttals of some of your arguments above, which I thought on deeply- going through my own research files and records before responding- I do believe in your expertise.
My concern is that your very valid concern about fake rothschildianum and plants with mislabeled parentage might be getting extrapolated to a wider population of plants than is really the case for the reasons I note above- or at least to certain parties. I share your view that there are a significant number of fake roths out there.
A few years ago, someone asked me why I was only buying flasks of Paphs like rothschildianum to grow and sell instead of making my own crosses from my own stud plants.
My response was that I thought you might get one really cutting edge rothschildianum- the kind where a division would sell for $5,000 or more- once every 4-5 flasks. And even then, some sib crosses just don’t work out and there is not yet the history and systematic knowledge to make better selections for parental pairings. And so, in order to stay on the cutting edge and sell flasks for $200+ each and NBS seedlings for $150+ each, you really needed to bloom out 40-50 flasks worth of plants every year or spending $50-75K on a handful of the best current divisions from other breeders willing to sell them.
That is the reality I think – that while the progeny overall are better today, the number of really top flight plants and home-run sib crosses remains very small. And while there are a number of fake or over-stated plants in the market, the criteria by which many of them can be identified are also criteria that I think can apply to genuinely identified plants with accurately documented ancestors.
