What kind of Coelogyne is this?

[nenella]

My Mother gave me a present whilst I was visiting her..
It's a Coelogyne...? not sure what? She told me it's a 'densiflora' - I think it's more like a "Coelogyne pulverola" or "pulverula" from pictures I've seen on the web....
Here are a couple of pictures of the plant she divided, which luckily for me was in flower whilst I was over there, unfortunately the close up is blurred..
I would also be grateful for any info on it's culture.I haven't really found any 'real' info on it..she grows it outside planted in a mixture of sand & charcoal.

Any info would be very appreciated. My mum tells me it's a 'tough' & very hardy plant.

I agree with you that it looks like Coelogyne pulverola, although I am not very familiar with this genus. densiflora (also known as massangeana) looks a bit different...
I can't find any growing info either on internet, but did find stuff on Orchidwiz, if indeed this is the correct name.

According to Orchidwiz (if it's pulverola), it needs bright light, temps around 25°C during the day (plus/minus 6°C) and 18°C at night, all year round. 80% humidity, heavy watering while in active growth, and needs a fast draining medium. They supposedly hate repotting, which some say delays blooming up to 3 years.

Hopefully someone who actually has this plant will be able to give you more info. I'm assuming your mom owned it a while sinc she tells you it's tough. In that case, her way of growing seems pretty successful!

Ohh dear! 3 years!!! I've just realised I didn't post the photo of 'my piece' of it ! which is from the one in the picture...which she divided about 6 months ago
here it is...

Good stuff Nenella. Looks like a Coel Masengeana to me, IMHO

I think its pulverola too.The petals on massangeana are flatter and the lip just a little different....Great plant!!

Bon jour Nanella,

The correct name for your plant is Coelogyne tomentosa according to Coelogyne expert Ed deVogel at Leiden (Orchid Monographs, vol. 6. 1992. Coelogyne massangeana and C. densiflora are considered synonyms.

Coelogyne pulverula is a synonym of C. dayana but that is a rather different species wih yellowish sepals and petals and a nearly solid brown lip.

Coelogyne tomentosa is known from elevations of 1500-2100 m. That said, it is routinely grown under intermediate (rather than cool) temperatures here in the U.S. and does just fine. I would avoid giving it too much heat, however.

Hope that helps, Eric

Nenella do a Google search for Coelogyne dayana and see how your plant's flowers compare. You need to look at how the plant is flowering. Coelogyne dayana flowers from a pseudobulb which developes after the flowers whereas Coelogyne tomentosa (syn Coelogyne massangeana) flowers from an aborted pseudoibulb that does not develope further. Coelogyne dayana is a very hardy plant.

Hi all & Thanks for all the info...
I have just asked my mum about the flowering & pseudobulbs..as I havn't got the foggiest..
I have had her a month and nothing has changed (no leaf loss or colour difference or new growths....)
I tend to think it's a "Coelogyne tomentosa (syn Coelogyne massangeana)" also because the poor thing ended up in a suitcase which got 'lost' for 5 days...& as it hasn't budged..I believe it's a "very very very Tough plant"....
The mix It's in does leave me a bit perplexed as it's a mixture of sand & charoal (according to mum who transplanted) but looking at it it's more like 'black sand' and nothing else...(no chunks)....
I will keep you posted as not much info on this...

Nenella, tonight I have learnt something. Your plant does not look like Coelogyne tomentosa (syn Coelogyne massangeana) to me . It looks like what I know as Coelogyne dayana so I pulled out my book by Clayton on Coelogynes and looked at the pictures to see if I was correct. Well I could not find a picture of Coelogyne dayana so when all else fails I look in the index. And guess what? Coelogyne dayana is a synonym for Coelogyne pulverula. I rechecked the pictures and there is a picture of Coelogyne pulverula which looks like your plant and what I have as Coelogyne dayana. So your plant IS Cologyne pulverula after all and definitely NOT Coelogyne tomentosa/massangeana. Do a Google search for Coelogyne dayana or Coelogyne pulverula and let us know whether you agree or not.

I agree with Mike. This is not a Coelogyne tometosa (syn. C. massangeana).
According to the flowers and bulbs it must be a Coelogyne pulverula (syn. C. dayana).
