Bulbophyllum dentiferum?
Hey Bernard,
This looks to me to be closer to Bulbophyllum dentiferum, rather than Bulb. taeniophyllum.
This one has the dorsal seta and petals with dark acuminate apex. Also, the margin of the dorsal and petals seem to me to be erose.
Refernce: Gunnar Seidenfaden, Notes on Cirrhopetalum Lindl., 1973
What do you think?
Cheers.
Gary
not sure
It seems to be pretty close to the same as the post by Bernard here http://www.orchidsonline.com.au/node/4865 Is his likely to be Bulbophyllum dentiferum as well?
I would like Bernard's opinion on your points first. Actually when this was posted I was only going off the original name under which the plant came to me as. That turned out to be a synonym of the present name.

Bulbophyllum
We have had one or two posts with the same queries as we have here. I too have Seidenfadens 'Notes on Cirrhopetalum'. I also have his later book 'The Orchids of Peninsular Malaysia and Singapore' By G.Seidenfaden & J.J.Wood 1992. Perhaps the following description by these authors will throw some light on the subject,
"Bulbophyllum taeniophyllum:
"Rhizome, psuedobulbs and leaves as in B.dentiferum. Scape to 12cm long, dull purple, with about 10 flowers. Dorsal sepal almost round with a very short tip, edges toothed towards the tip, 7 by 6.5mm, whitish with dull purple spots.
Lateral sepals with upper edges joined in their apical halves, their tips narrowly pointed, total length 1.6cm, greatest width 5.5mm, white with small purple spots which are larger towards the tips. Petals 4 by 3mm, ovate, tips rounded, edges very short-hairy, surfaces papillose, densely covered with small purple spots. Lip curved, 3.5mm long, greenish with fine purple spotting. Column with very long slender erect stelids".
'Personal comment'The lateral sepals on B.dentiferum are joined at their apical half and are more acute at the tips than B.tainiophyllum which are slightly more rounded at the tips.
Hope this helps.

thanks Bernard
So for the present time both these posts (yours and mine) remain as they are presently named?
Thanks also to Gary. It is always good (and right) to question the ID's we have arrived at if there is a question mark in anyones mind.
As long as we all handle this process with respect for each other we will all be much wiser for the excercise of confirming the information we have at hand.
These are the things that makes Orchids Online a great place to be a part of I believe.

Bulbophyllum dentiferum?
Hello again Bernard,
I’ve just been recently trying to confirm the ID of a plant that I photographed in December as Bulb. dentiferum.
Using Gunnar Seidenfaden’s keys (Notes on Cirrhopetalum, 1973 and Orchids of Peninsula Malaysia and Singapore, 1992), he initially separates out Bulb. taeniophyllum and Bulb. dentiferum using the margins of the dorsal sepal as to whether they are entire or erose/serrate/ciliate.
Bulbophyllum dentiferum - dorsal sepal erose to serrate with seta (hair-point) at the apex, petals erose to ciliate and usually dark at acuminate apex. Going by the measurements given for the lateral sepals (3-5 x 15-20 mm), Bulb. dentiferum would have longer flowers.
Peter O’Byrne (A-Z of South East Asian Orchid Species, 2001) says that Bulb. dentiferum produces more flowers than most in section Cirrhopetalum. The 12-30 flowers often form a full circle or a double whorl. I’d love to see one with 30 flowers! He adds that the amount of pink spotting on the sepals varies considerably.
Bulbophyllum taeniophyllum – dorsal sepal with entire edge and a short tip, only petals erose or serrate. Lateral sepals total length 16 mm and greatest width 5.5 mm, which I interpret as for each lateral sepal. Please correct me if you’ve interpreted this as being for the two sepals joined together. About 10 flowers.
I find it interesting to note that the petals of Bulb. taeniophyllum are described (1992) as having surfaces papillose, which I had missed in my previous research.
I wonder whether the lateral sepals of both of these species may sometimes not be joined along the centre in some cultivars. I have seen photographs of such examples, but not examined them closely to check out the ID.
There is no mention that I can find in my limited literature that the outer surface of the lateral sepals of what I think to be Bulb. dentiferum are papillose - as I’ve just noticed in the close-up photo that I took.
I’ll post my photos so you can see.
Cheers.
Gary
