Den. aphanochilum---anybody know about it?

I acquired this little guy last night at my OS raffle, but I'm not finding much information about it. Baker and Baker does not have this species, and the other culture information I've found is pretty sketchy. Is anyone growing it or have any knowledge about culture, particularly about winter treatment?

Apparently it blooms on bare canes after leaves drop; does this mean a cold, dry rest? Thanks in advance, and sorry for the rotated photo. I can't seem to change that.

From what I can tell it has a very narrow temperature range in nature. Minimums are around 16C to 17C all year round......not much variation at all. Maximums are interesting being between 20C in winter and 24C in warmer months. A very consistent climate.

Winter is actually the wettest season. Water can be reduced in winter however if you have short days in a temperate climate. But never allow it to completely dry out. Reduce fertiliser if you reduce watering. Depends on how you grow it but for example in my climate I would water far less and not fertilise at all in the shorter winter months when growth would slow down.

I am guessing your climate is cooler than mine being inland from San Fran? Not sure really but I am guessing you have shorter cooler days in winter anyway.

It sounds like they do better on cork or bark mounts but humidity needs to be very high all the time if you grow that way. Their growth habit would be better suited to mounting but watch the watering and humidity.

Baker suggests there can be extremes of 12C as a minimum up to 28C as a maximum occasionally. The Den is found at fairly high altitudes in Indonesia being 4000 feet up the hill!!!

Light requirements = 2000 to 3000 FC but Baker states there are very few clear days. It's interesting as some months might only have 2 or 3 days of clear light.
Fertiliser at 1/4 to 1/2 strength.

It's an intriguing Den and one I have never seen or heard of before. I wish you great luck with it and I know you will grow it well. The flowers are crystalline looking and tubular in shape growing in bunches when grown well. I think it's a stunner!!!

Wow, thanks for all the information, Bolero. Where are you finding it, in the Baker Dendrobium book or Orchid Wiz? I subscribe to the Baker culture sheets online, but the species is not listed there. Is there a synonym I'm not aware of? Anyway, that's very helpful.

It sounds like this one will reside inside my house in my "indoor greenhouse" where the humidity ranges from 60%-80% and temperatures from around 16C to 27C depending on the time and the season. Where I am we have many days in the 30C and above during the summer, and frequent frost in the winter, so the swings would be too large outdoors. We'll see how it does at human temperatures, more or less. I'll feel lucky if I ever get to see those blooms in person! I agree, the pictures are intriguing--virtually no lip.

Mostly Orchid Wiz and some of that information came from Bakers so I am not sure why you can't find more. Not all the information came from them but a lot did.

Your indoor greenhouse sounds perfect to me.

I should mention this Dendrobium used to be called......... Pedilonum aphanochilum and also known as Chromatotriccum aphanochilum.

Also this species is exposed to as much as 2 feet of rain each month during winter.

Orchidwiz! I hate that they don't support the Apple system. And I'm green with envy!

I had to do a Google search so I could see the flower and found this. Orchids wikia is one of my favorite go to's for culture.

Yes, I saw that too, thanks! It cracks me up that the common name is "The Insignificant Lipped Dendrobium ".

I am not sure why they don't support that OS. I believe there is a tablet or phone version coming at some point though.

Love it, one click and I get lots of information in one place. It's helpful when I am judging as well.

I would buy an ipad if that meant I could get Orchidwiz. Are you listening, Apple? I have a Macbook and an iphone, and I'm really hesitant to get a tablet and have to learn a new system.

Have a look at the Surface Pro 4 if you decide to get a tablet, it's not an apple product but a lot of reviews rate it highly and probably higher than an iPad.
