Hi Neville,
These are the picts of Dendrobium, that I think Dendrobium aries, is it match/correct to your literature?
Regards
Frankie

Hello again
If you were looking for the recent posts on Cleisostema or vanda, I have moved these into new threads. To find these threads, just click on "Orchid Species" in the blue menu at the top of this screen
Orchid Spring Discussion Board > Orchid Species > Dendrobium section Spatulata
then select either "Vanda" or "Cleisostema spp" from the list of threads.
You can also create new threads from here if your topic is not about Den. section Spatulata. Just navigatew to the correct area nadclick on the "Start New Thread" link found either at the top or bottom of list of sub topics.
I hope this doesn't cause any confusion.

Seck poh,
my first thought was that the Dendrobium could be D. moniliforme (L.) Sw., a species that occurs in Japan, Korea, China & Taiwan. This is the Type species for section Dendrobium. Small-flowered forms of this species (flowers 2 cm wide)with an acuminate midlobe exist in China; see page 181 of "Native Orchids of China in Colour", Chen, Tsi & Luo, Science Press (1999). My second thought was that it could be Dendrobium faulhaberianum Schltr. (syn. D. oxyanthum Gagnep.), which occurs in Vietnam & China and is in section Breviflores. D. faulhaberianum has flowers 2 cm wide, but has a relatively larger mentum than your photo shows, and the front half of the midlobe (upper surface) is covered in short hairs all the way to the apex; this cannot be seen on your photo.
I cannot pass any judgement on your Cleisostoma-like thing without dissecting a flower. I cannot even say what genus it belong to. The apparent lack of a callus blocking the spur aperture (which may just be due to the angle at which the photo was taken) and the teeth at the column apex (hard to tell if they arise from the column or the rostellum) suggest it is probably not a Cleisostoma.
The messages following this post concerning the Cleisostema species have been moved to a new thread "Cleisostema spp" - Steve

Hello Peter,
Thanks for your opinion on the ?Dend pseudoconanthum.
I've 2 other species I need someone to help out with their ID.
The first is a plant from Borneo. It looks very much like a cleisostoma but the lip is different.
The second is a dendrobium (I'm not too sure) from Vietnam.
Thanks and best regards
Seck

Seck Poh,
Your plant looks very much like Frankie's. The size could indicate a problem; the Typus had flowers that were significantly smaller than 6.5 cm. Where did you get your plant from ?

Hi Peter,
Came across this discussion while looking up information on Dend pseudoconanthum. I've a similar plant/flower as the one posted by Frankie which you thought could be Dend pseudoconanthum, the only difference is the flower of my plant is larger about 6.5 cm across cf 4cm that of Frankie's. I've attached a couple of images here. Tell me what you think.
Best regards

Frankie,
that is the species I've been calling Dendrobium pseudoconanthum J.J.Smith. It is quite common; I've seen many specimens, but hardly ever in flower. The flowers I saw were darker than yours and had a shorter more pointed midlobe. Cribb's description is rather bare and lacking in detail because he only saw the herbarium sheet of the Type and one recent photo.
Cheers,
Peter |

Dear Peter,
After a year in my garden, finally this Dendrobium bloom, plant reach 2 meter tall, I got the plant from Mr. Tampang, it collect from central sulawesi, it seem related to Dendrobium conanthum, but conanthum dont exist at sulawesi. I try to find in Cribb book "revision latourea and spathulata" but not match with Den. pseudoconanthum or busunguense. Could you help...
Regards,
Frankie

Hello frankie.
The plant on the right in your most recent pair of photos looks exactly like Dendrobium trilamellatum. Unfortunately, you still haven't put a ruler in the photo so I can't tell if it is the correct size. The flower (in your earlier photo) looks very much like D. trilamellatum, although since we cannot see the lip details or know the size, it is impossible to be certain. You most likely have a form of D. trilamellatum there.
I have never seen D. aries and I haven't taken a photo of it. There is a photo taken by J. van Bodegom in Schuiteman and de Vogel's CD-Rom "Orchids of New Guinea Vol 2.... Dendrobium". You would find these CDs very useful .. there are now 3 of them, and a further 3 are due out over the next 2 years.
cheers,
Peter |

Dear All,
This is the pict of the plant that I assume natural hybrid between Den. trilamellatum and Den. canaliculatum (Right pict), and the left is Den. leporinum from Halmahera/Maluku. I saw some color of leporinum at some nursery, from pure white, pink to brown petal.
Nev or Peter, could you show for me pict of Den. aries? I've never seen the pict beside in Cribb book, revision dendrobium section spatulata & latourea. Thanks
Frankie

Hi,
I am no expert, but at a first glance, the photo on the right looks like a cross between D. discolor and D. tangerinum.

Frankie,
I see what you mean but your left hand side photo does not suggest to me that you have a D. discolor x antennatum. There are a number of species in the antennatum group that share some similarities. These last two photos show alot more and again yes there are some interesting differences between that and D. discolor. I will have a closer look at the se when you have sent the photos of the plants. I am not readily influenced by plant size and thickness of leaves although they may suggest the plant is of hybrid origin. For size you might consider the difference between a normal form of D. bigibbum and that which we use to call var. compactum and which is now called D. lithicola in Australia. I am not a support of the name change but that is a matter of personal opinion.
Don't worry about your English. Its ok and you are understood clearly. These last two photos of yours are good and illustrate some of the points you are making.
Best wishes
Nev.
PS I have seen a photo of D. leporinum and it does look like the left hand one. In situations like these i prefer to dissect the flowers and compare them. |

Peter and Nev.
in my opinion the top left is similar with the plant in Lowland orchids of PNG (discolor x antennatum), plant is more look like big Den. antennatum than Den. discolor.
But top right, plant have very different characteristic to Den. discolor, its more similar to (Den. stratiotes, strebloceros or bigger antennatum), thats why many nursery in java usually labelled as Dend. strebloceros "brown"
Bottom right, I believe this plant is natural hybrid or related to Den. trilamellatum and Den. canaliculatum. the leaf is very thick and plant do not like canaliculatum or caronii. its look like fat and mini canaliculatum  ) I will take the pict of the plant tomorrow.
the problem is my english very bad, so difficult to explain in detail  (

Frankie,
Further to my earlier suggestions D. discolor is quite a variable species here in New Guinea over its range. We have something similar but smaller then some found in the Western province and even around Port Moresby and in fact this one of yours wich is similar in its labellum features to one which was described qas a variety( I cannot remember what it is) There has been some moves to actually separate this variety and make it a new species. Last year i was shown a form supposedly collected from the Vanimo region That to my eyes looked identical to the North Queensland form of D. discolor. It far surpassed any thing I have seen in the Central and Western provinces. The infloresences were very long which carried larger flowers and more flowers per spike. So the species is quite variable and it is understandable that some people would want to describe them as separate species some times and in some instances I have felt that there appears to be some justification for this.
The bottom left species if it is D. canaliclulatum should have thick fleshy leaves, narrow, up to 6 but quite often less. The pseudo bulbs are short and thick and often - as the common name Onion orchid implies - looks abit like an onion. The Papuan ones are often larger p[lants than the ones we find in the western Province and the flowers usually larger. There is some interesting variation across the borders of the countries from Mackay, Queensland to Cape York, and the southern provinces of PNG to Papua.
Regards
Nev. |

Frankie,
I agree with Peter's comments. However if you want some clues the top left is related to d leporinum, top right D. discolor, Bottom left could be any thing but look at the plant habit and size of flower as it may be D. canaliculatum and the bottom right has feature of D. trilamellatum. If those leaves in the back ground be long to the plant then i certainly would be checking against that one. Further the features of the mid and side lobe look like that . i have hybridized D. trilamellatum before and it looked similar (but not the same) as this one. The features of D. trilamellatum are there and this species is variable in colour ranging from dark honey brown to gold.
As peter pointed out the plant habit with these is very useful.
regards

Frankie,
your question should be "species or hybrid ?" (not "species or natural hybrid ?") because unless you collected the plants yourself, you cannot guarantee they originated in the wild.
The answer is .... it is virtually impossible to tell from a photo. It is even harder when there is no scale to indicate the size, and completely impossible when the photo doesn't show the lip details clearly. The one at the top right looks like it may be a form of D. discolor or a hybrid of D. discolor, but you simply can't tell from a photo. The one at the top left is similar (but not identical) to a putative natural hybrid I found between D. discolor with D. antennatum... see pages 261-263 of my Lowland orchids of PNG book. The bottom right could be a form of D. trilamellatum, or a hybrid of D. trilamellatum, or something totally different !.... a big clue with this species is how the whole plant looks.
The most interesting one is the bottom left with 18.09.2004 printed on it. Do you have any better photos of this plant ?

Dear Peter
I attached photograps some of Dendrobium from section Spatulata with intermediate characteristic between some species. All the plant come from Papua. Is it sp. or natural hybrid?
Regards,
Frankie
