Ken & Chris's Orchids
Gary Yong Gee says.... Ken and Chris' Stenocoryne vitellina is Stenocoryne aureo-fulva (syn. Bifrenaria aureo-fulva). Stenocoryne vitellina refers to another species with differently shaped flowers. We have had plenty of seedlings also labelled incorrectly here in south-east Queensland.

********************************************************************************************* Laelia gouldiana $7.00
These plants were purchased from Tinonee Orchids and
have been grown on by Sharon. Laelia gouldiana (syn Laelia autumnalis)
is found in Mexico where it grows as an epiphyte or lithophyte, although
may now be extinct in its natural habitat. Laelia autumnalis was initially
introduced to cultivation in 1836, and was described by Lindley in 1831.
This is some conjecture about Laelia gouldiana with some claiming that
it is merely a more colourful form of Laelia autumnalis, while others
suggest that it may be a hybrid of Laelia autumnalis and Laelia anceps.
**************************************************************************** Gillian's Orchids
Gary Yong Gee says....Gillian's Laelia anceps does not have the correct lip shape for the species and looks to me be a L. anceps hybrid. This would also account for the extremely short inflorescences.
******************************************************************************* Mavis and I had a recent visit to Lyn & Lloyd Mullen in Queensland and were delighted to see a huge range of species orchids in Lloyd's bushhouse. Take a look HERE While we were in Queensland, we attended a meeting of the Morton Species Orchid Group and saw many unusual species orchids for the first time. Take a look HERE After the meeting, we were taken to see Phil Diamonds orchids. Phil had much too many species to take to the meeting. Take a a look HERE And my thanks to Jay Pfahl and Dalton Holland Baptista for correcting some of the names. I really do appreciate your input. (At least it tells me that someone is reading the pages ;-) Tony
**************************************************************************** Peter & Shirley's Orchids Stenoglottis longifolia
*************************************************************************** I have e-mailed Hans Hermans seeking a shipping date, indicating that in the absence of a confirmed date, I will need to delay his shipment until September as we have 230 Phalaenopsis species and hybrids from Joseph Wu Orchids in quarantine, and the order of over 500 plants from Sakdisri and Daughters Nursery due in late July. For those of you participating in the order from Sakdisri, I have sent out pro-forma invoices for checking. Please ensure that you pay me at the next meeting for the cost of the plants as I need to give the cash to Tony and Mavis before they leave at the beginning of July. We had an inspection on Monday 16 June and approximately 60-65% of
the plants in quarantine have been released. However, some spotting on
mature leaves of Dendrobium species D. griffithianum, D. palpebrae and
D. dixanthum has resulted in the plants being taken across to AQIS for
identification. Hopefully, this is just inactive bacterial spotting and
should not create any problem - I will let you know the outcome at the
meeting.

******************************************************************************* Tom & Pat's Orchid Brassavola sp
******************************************************************************* Why did they name it that! Last month, we made some progress with the 'botanical' rules following the start made in April where I commented on some of the pronunciation rules. To finalise the pronunciation rules which is where we started out back in April, another common example is ii which is often pronounced e-i. Sometimes, a dieresis ( ) is placed over the second vowel to show that it should be pronounced separately (eg Aerangis), however is this symbol is often omitted because it is difficult to typeset. Further, a terminal ending 'ensis' to the specific epithet means 'from the place' (eg Oncidium riograndensis). So, when faced by a strange name, firstly break it up into syllables containing just one vowel or diphthong (as shown in April). The consonants will largely look after themselves. For example Acanthephippium sylhetense becomes A-can-the-phipp-i-um syl-he-ten-se, or phonetically Ah-kan-the-fip-ee-um sil-he-ten-see. As you see, the phonetic conversion uses the English pronunciation. To finish off, here are some other facts that might be useful to know The botanists and breeders have a significant impact on plant names. Sticking with species for the moment, Dendrobium kingianum is a very variable species with many different colours ranging red to white and all shades in between. For example, Dendrobium kingianum 'Corrigan's Red' is a particular cultivar. This was probably a plant of Dendrobium kingianum selected for a special characteristic, its deep red colour. This epithet is written in roman letters enclosed by inverted commas and is always the last name. Plants which bear this name should have been reproduced by meristem (tissue) culture, or a division of the original named plant. However, often unscrupulous dealers will use a recognised cultivar name to increase the price of a particular plant which may at best be similar to that which originally named. Compare this to the earlier example where the epithet album was used to indicate a more general feature. But the story doesn't end yet. So far we've only scratched the surface. I hope that you'll find this intriguing if not interesting!. Sometimes we see an X after the generic name before the specific name, yet everything else looks the same as a species, eg Dendrobium X delicatum (recently described Jones D asThelychiton X delicatus). In this case the X indicates that this is a naturally occurring (man didn't have anything to do with it) hybrid between Dendrobium speciosum var. tarberi and Dendrobium kingianum. While there is continued debate about whether this is in fact a species (there are limited examples found in the wild) there is no agreed position. The simplest test is whether the plant ' breeds true', ie whether the progeny from a self or sibling pollination are the same as the parent. However, to avoid this becoming a debate, we'll continue to refer to it as a natural hybrid The conventions and rules about naming species, the hierarchical system used to classify orchidaceae, and some other letters often seen after orchid species names when reading botanically correct publications follow. I'll look at why the names change, and what does the term 'synonym' mean. Some other rules given by Morrison & Webb (1991) are: While there is much more that could be written, I feel that these simple rules will help enormously. If you have a plant with an unusual name, try using these rules and see whether it helps you to make sense of it. The Species Society's library has a copy of Hawkes 'Encyclopaedia of Cultivated Orchids', which, in its index at the back, has the phonetic pronunciation of many orchid names. It was reading through this that first induced me to explore a little further to find out what the rules were. The book that I have used for much of this series of articles is Morrison, G.C. and Webb, M.A. (1991) 'The Essentials of Orchid Growing' Kenthurst; Kangaroo Press. It only costs about $30.00 or so, contains a lot of useful information (but no pictures!) and I thoroughly recommend its purchase for serious orchid growers. Over the past three months, we've taken a short journey through the mysterious and perplexing world of botanical names and descriptions. Now its time to take stock of what we've learnt (if anything!). I started by introducing the notion of orchid species. You may remember that there are estimated to be between 17,000 and 35,000 different species in 700-1200 genera. I hope you now understand the difference between these two words, as they are often mixed up. Then, using the botanically correct method, we found out how to write orchid names - the generic name starting with a capital letter, the specific epithet (name) in lower case letters, and the whole lot in italics. You will also know that when you here someone say "Cymbidiums", they are using the common name for a class of plants, since all generic names are singular, and that someone who uses the specific epithet name only, eg" niveums" is also quite wrong since it is singular and must be in preceded by the generic name, although there are specific epithets such as Laelia anceps which is quite correct. Along the way we also visited the naming conventions, the use of additional epithets, and cultivar names. The thorny issue of natural hybrids, indicated by the letter X before the specific epithet also reared its ugly head. The second instalment dealt with the heavy stuff, the classification system for all living things, and eventually, the groups to which Orchidaceae (orchids) belong. We encountered a few early botanists like Linneaus, Swartz and Lindley who were responsible for many of the present orchid generic and specific names. While it may annoy us that the names of our orchid plants keep changing, at least it tells us that someone is interested in the taxonomy of orchids which should be seen as a positive sign. I also explained synonyms - often an earlier or invalid name that has become popular through custom and use, and continues to be used even though incorrect. Growers need to be careful about rushing out and changing all their plant labels each time someone tells them their plant is incorrectly named as there have been many revisions which have subsequently been discounted. Before you make such changes, try to find out where the revised name came from, and the standing of its proponent in the botanical world - that is, was it reported in a recognised journal such as Orchid Monographs from the Kew Herbarium or similar. If not, it is wise to err on the side of caution and leave well enough alone. It is also true that many species, and probably some genera have not yet been described, and given the disappearance of the world's rainforests, may never be! It is said that in the disastrous Indonesian fires some years back that many of the unnamed species were lost forever. Generally they are the peculiar, small, insignificant orchids (described as 'botanicals') grown by enthusiasts. I have also tried to provide a simple set of rules of thumb to help you pronounce those terrible names. We found out about diphthongs, about hard and soft sounds, about syllables and the placement of vowels. As I said in the beginning, it was like going back to school English. I hope that it has helped, and that some, if not all of you feel more confident about trying names you previously gave up on. I thoroughly recommend Hawkes Encyclopaedia of Cultivated Orchids as it gives the phonetic pronunciation of many more names that any of us are likely to need. Perhaps this series of articles have prompted you to read a little further - if so Morrison and Webb's book is a worthwhile investment, and has a lot of useful information about orchid cultivation, although few pictures of orchid flowers. With respect to the particular rules for naming hybrids, many are
named after their originator, for example Moirara which is hybrid of Phalaenopsis
x Renanthera x Vanda named after its breeder W W G Moir, or MacLelllanara
which is a hybrid of Brassia x Odontoglossum x Oncidium named by its breeder,
Rod McLellan Co. Other hybrids use a combination of the genera, for example
Brassolaeliocattlaya which is a hybrid of Brassia x Laelia x Cattleya.
On our recent trip to Thailand, what was confusing to people was the correct
spelling of these compound names when I asked them to ensure that they
were written in full and spelt correctly. I had hoped to find a simple
set of botanical rules that I could pass on, but it was not to be. I will
undertake further reading and research to learn what I can so that I can
pass it on in a future newsletter.
