[OGD] Peter O'Byrne and Andy Easton

2004-07-18 Thread David P Banks
Peter O'Byrne, in his last email on this digest, pointed readers to his
discovery of a new Vanda species, documented on the following website:

http://www.orchidspng.com/cgi-bin/discus/show.cgi?6/5960

He went on to say "To put this discovery in context, there have only been 3
other new Vanda species discovered since 1930, and none in the last 20
years!"

Here is the excerpt from that website (minus the two photos)

"I've just returned from a trip to a remote part of Sulawesi, where I found
a Vanda species growing in huge numbers on trees in 2 mountain valleys. I am
fairly certain it is an undescribed species. When I have finished doing
drawings & a full description, I'll circulate it around various experts and
see it they concur. If no-one can suggest a prior name for the species, then
I'll publish it in this year's MOR, probably as Vanda jennae or Vanda
jennaiana. If anybody has any information about this species, please contact
me.

A few details: the largest plant I saw had a stem that was 175 cm long, and
had leaves on the upper 80cm. Leaves are up to 34 cm x 42 mm; leaf apex is
bilobed, truncated, but rather variable in shape. The largest inflorescence
was 21 cm long with 8 flowers. The flowers are ~45 mm wide, lightly fragrant
and have a highly mobile lip with a very short spur."

The photos are very impressive, and certainly evidence of a species I have
never seen before. Peter is to be congratulated on this discovery of such a
horticulturally attractive species (if it is proved to be undescribed and
new to science). My only disappointment was that Peter flagged its new
"name" before all the taxonomic formalities have been conducted and validly
published. This could open the door for "someone else" to name this species
before the publication date of the next issue of the "Malayan Orchid
Review". Personally, I feel such "manuscript names" be kept private until
publication...to avoid a needless expansion of an already huge list of
orchid synonyms.

Whilst it has been mentioned (more than once) that Peter is not a "trained
taxonomist", I personally value his taxonomic determinations and knowledge
of Southeast Asian orchids a lot more than many with those "important
letters" after their name. Peter also studies these plants in the wild, and
is enthusiastic and passionate about his topic. I have never met Peter in
person, and have only ever corresponded with him by email, and he has always
answered my questions quickly and with a lot of supporting evidence. I value
his orchid-related opinions.

He has written two major books - "Lowland Orchids of Papua New Guinea"
(which also includes many of Peter's colour photographs and line drawings
depicting the species represented. Most of the orchid taxonomists and
hobbyists I know use this book as a key reference work for the orchids of
New Guinea. Not bad for an amateur! His other work the "A to Z of South East
Asian Orchid Species" is a great introductory field guide to the vast
numbers of orchids in this region. There are many species illustrated in
this book that I have not seen published elsewhere. Certainly, a "must have"
book. Peter's popularity in Singapore is so popular that he has to even go
shopping in disguise, to avoid recognition! (See photo on the back cover of
the book!). He has also written numerous articles and has described a number
of new orchid species in the "Malayan Orchid Review".

Then Peter later on wrote... "So, Andy (Easton), please enlighten us all
. what has your most significant contribution to serious orchidology
been ? Other than playing politics at AOS (yawn) and using the web to
rubbish people you've never met?"

Well, really the personal orchid interest of Peter and Andy couldn't be
further apart. Peter is into species, especially miniatures (his email
address features Oberonia) and botanicals. I've never heard Peter mention
the word "hybrid". So that is why Andy is probably unaware of what Peter's
contribution to orchid literature is.

On the other hand, Peter (being the species nut that he is) probably only he
ard of Andy Easton in very recent times (like since email became so
fashionable).
Andy has been (and still is) a world leader in breeding first class orchids,
proven over many decades. His foresight and ingenuity kept him a generation
or two ahead of his contemporaries, and he revolutionised the way tetraploid
orchids were used in breeding. The showbenches and award tables have been
overflowing with Easton-bred cymbidiums, in miniatures, intermediates and
novelties as well as standards. How many times have we seen the name
'Geyserland' as a cultivar name used for choice orchids? Andy's prowess is
certainly no limited to his main interest in cymbidiums. He has bred
outstanding lines with the Odontoglossum alliance, and pioneered work on the
tetraploid lines of Maudiae-type paphiopedilums as well as the classic,
complex slipper orchids, especially in the greens and autumn tones.

I have known Andy for many years, and

[OGD] Taxonomy of "Epidendrum pugioniforme"

2004-07-18 Thread David P Banks
WARNING!!! ORCHID RELATED QUESTION

Taxonomic status of Epidendrum pugioniforme Regel (1890)

I note in the new Withner/Harding volume on "The Cattleyas and their
Relatives: The Debatable Epidendrums", that there is no reference whatsoever
to the Mexican species Epidendrum pugioniforme.

Is this perhaps just an oversight? As (to me anyway) it belongs in the same
section (or genus) as Epidendrum falcatum (Coilostylis falcata) and
Epidendrum parkinsonianum (Coilostylis parksoniana). I was initially
surprised to see Epidendrum ciliare (Coilostylis ciliaris), but can see how
it falls into this natural group.

Are any readers aware if either (or both) of Carl Withner or Patricia
Harding are contactable via email? If so, please contact me privately with
their details.

David Banks

It appears to me that the use of activated charcoal has been found to enhance
the growth of seeds and seedlings in flask, and since that time, people have
been trying to work out why this should be so. They have therefore advanced
various useful theories, none easy to prove. So, basically, we are putting in
charcoal because it works. I like Aaron's "magic" explanation - it is almost
as good as the rest.

Hi there,

FS of Cymbidium golden elf is about 1/2 metre leaf length with bulbs
about 2.5-4 cm in diameter.

These are one of the very few cymbids with erect spikes that can flower

[OGD] Charcoal

2004-07-18 Thread Martin Epstein
Many years ago I became disenchanted with bark as
a potting medium.  I wanted something that would
hold up better, so I tried things like Turface,
Aliflor and Perlite.  They worked, sort of, but
none gave me the overall results I was looking
for.  On a trip to Florida I stopped by a nursery
that had all their plants in charcoal.  They were
overgrown had lots of weeds, and had obviously
not been re-potted in several years but when I
looked between the weeds I found that the orchids
were growing well in spite of the obvious neglect.
I tried charcoal alone and found that in the
Northeast it didn't retain enough water unless I
watered at least once a day, so I tried mixtures
of charcoal and sponge rock (extra coarse
Perlite) and found that a mix of two parts sponge
rock to one part charcoal gave me good water
retention with good drainage.  I eventually added
a little chopped sphagnum moss to the mix and
settled on five parts sponge rock, four parts
charcoal and one part sphagnum moss.  For me it
was the holy grail.
In response to government regulations the town I
lived in started adding KOH to raise the pH to ca
8.0-8.3.  They never seemed to get it right,
however, usually ending up around 9.3.  I was
concerned about this and decided to see what
effect charcoal has on the pH.  It raised it
considerably, but my mix had a smaller effect
because the sphagnum moss was quite acidic.  I
added a little vinegar to my water and this have
me the desired pH.  My plants grew well, and but
I really have no proof that this was because of
the pH control.  It made me fell better at least.
A year ago I moved; new water supply (lower pH
but 40 ppm of sodium!); lights instead of a
greenhouse; RO water instead of municipal water.
I saw the thread on charcoal and decided to do a
few tests.  I found that the conductivity
increased by ca 150 5s in one hour when I added
20 grams of charcoal to 200 ml RO water, or to RO
water plus 30 ppm Calcium (as the nitrate) or to
a fertilizer (Peters 15-16-17) solution
containing ca 150 ppm nitrogen.  The pH of the RO
water jumped to 8.4, that of the calcium nitrate
solution to 8.0 (from 5.6), and the fertilizer
solution to 7.0 (from 5.3).  I suspect that the
charcoal has a significant amount of residual
potash which is extracted and raises the pH.
Rembember in the old days charcoal was used a a
source of lye in soap making.
In any case, my plants continue to thrive.  I
suspect that the lye is extracted in the first
few waterings and cause no long term problem.
This probably is not true in flasking media.  My
only problem is that with the large amount of air
movement in my plant room, combined with the long
days (16 hours) I am using cause the plants dry
out too quickly.  I am experimenting with coconut
chip (with some sponge rock and some charcoal).
So far no problems but too soon to be sure.
Anyway, far from adsorbing things, the
horticultural charcoal I use seems to be a net
contributor to the potting medium...at least
initially.

[OGD] Conserving Peter's Vanda

2004-07-18 Thread Martin Epstein
Nice looking Vanda, Peter.  How are you going to conserve it?
Sooner or later someone less scrupulous than you will find it. 
Indeed, now that the orchid world has heard about it there may 
actually be people looking for it, and I am sure they will, in time, 
succeed.  Perhaps they can back track your route.  Did you have 
guides?  Will they talk?  Perhaps if you had not published your 
finding it would have a better chance of surviving.

Of course you could propagate the species and distribute seedlings. 
This would take a lot of pressure off the plants in their native 
environment.  If you had done this and waited for the seedlings to 
mature before announcing your find to the world it's possible that no 
one would even look for it in the wild.

So what are you doing to save this new Vanda species???

Murray,

In my experience, a leaf length about 40%-50% larger seems a more-likely
"blooming size," but I have seen smaller plants bloom.

As far as "tips" are concerned, they are often billed as "warmth tolerant,"
but warm-growing appears to be more likely.

A.J. Hicks, astutely avoiding politics querried:

"I can't get Physan 20 (except by mail order only). I CAN get
Consan 20 for some bizarre reason. I know they're almost the same (there's
a bit of difference in the quats that make them up), but can anyone comment
from experience as to any untoward effects of Consan *specifically* on
their orchids before I use it and kill all my infinitely valuable tiny

I have always found Physan, Consan and all the other "quats" to be equally
effective in trashing my miniatures.  I must admit that before I use any of
these
compounds on my minis, which I grow indoors in an Orchidarium clone that cost
a small fraction of what a real Orchidarium would cost, they must be at
death's
door.  I actually do not think that they do any harm when applied as directed
and if the temperature is not too high.

[OGD] Vanda Locality Data

2004-07-18 Thread Peter O'Byrne
Nick Plummer asked: "Beautiful plant.  It must have been exciting to find
them.  If you publish a description, will you be permitted to keep the
precise locality secret?"

Nick, I can be as vague as I want. My options range from the precision of
" village, yyy subdistrict, zzz Province, Sulawesi, Indonesia" to the
vague "Sulawesi" to the totally useless statement "Indonesia". Obviously,
the more detail I give, the more useful it is to future workers, and the
more likely it is that someone will land a helicopter there and rip all the
plants out. There is a compromise to make  I'll decide later how much I
want to disclose. Since this taxon has such evident horticultural value and
such a small proven range, I'll err on the side of caution.

Finding these plants was hard, frustrating work. I first saw this species
some 5-6 years ago; one plant was flowering under a shade-net in an
orchid-collection in the garden of a house in a town in the Poso Valley. I
took some photos of the plant & chatted to the owner for a while. She was
from a different part of the island and had brought the orchids with her to
remind her of home, which is a quite common thing for Indonesians to do. I
came back to Singapore and, on the basis of the photos, decided that it was
probably an undescribed species, so I'd have to go back and follow it up.
The civil-war, which was just starting in '99, got much worse and for the
next few years it was too dangerous to return to the Poso area. By early
2003 the war had died down, so last August I went back to the Poso Valley.
The house was still there, but it had been heavily machine-gunned and was
standing empty  there was no sign of the owner and her family. The
shade-house was still there, but no orchids ... someone else was using it to
cultivate cocoa seedlings. The neighbours said the family had gone back to
their village, and asking around produced the names of the village and it's
subdistrict. The village is very remote, and getting there (and back) posed
some major problems, so I waited until this year and organised a special
trip. Yes, it was worthwhile ... the first one I saw flowering in the wild
was a real thrill. Then I saw the next one, and then the next one..
