Bulbophyllum armeniacum

[Andyhuang]

Got this plant few years ago from ebay, and wasn't sure if this is the plant. Never the less is very interesting plant. Flower is small, and appear white when it open aim at all direction,some petals have light orange color. It is growing indoor and just recently open the flower first time from bud. I wish I can get more information on line, but have not seen much articles. I am please to get advice from someone who has experience. By the way I am new in this forum.

Hi Andyhuang and welcome

I'm not convinced that is a bulbophyllum but I could be completely wrong. I would expect psudo-bulbs on a bulbophylum and I can't see any on that plant.

As you say, interesting one though.

Welcome to the Orchid Board. We have several knowledgeable members who are bulbophyllum collectors. They can probably help. Did you ask the dealer you purchased it from?

I have found a real interest in bulbos they are so different. Glad to see it's mounted, the best way to grow them.

If all else fails, you could call Tom at Carolina Orchids and he could tell you about it.

Hi Rosie, I just found out there is library book in UCI call Orchid of Sumatra by J B Comber regarding Bulb armeniacum, the article describe the pseudo bulb being small and disc shape, shiny green 2.5 mm by 3.5 mm diameter just above the rhizome. Mine photo did not catch the pseduo bulb close enough that you will be able to see. However the flower almost look exact the same except they are more orange color.Carol, I did not ask seller where he get his plant, at that time I was beginner and fascinated by this plant. Well thank you all for bring me source of information and I wish you have a happy holiday.

Really interesting, thanks for the update Andy. I had wondered if the p-bulb was very small, so that answers the question. Great to know

It's a Bulbo alright.

Just don't know if the species name is the correct name attached to it.

I'm not familiar with Bulb. armeniacum.

It doesn't mean it isn't a real recognized name. It could be.

And it doesn't necessarily mean that yours isn't what it is labeled as. It could be.

Have you thought about getting it identified by a lab that deals with orchid taxonomy or contacting an orchid taxonomist? I'm sure if you asked around, you'd eventually find the email to some orchid taxonomists, who'd be willing to help you out.

Okay...

Just thought of something else that could help you.

Have you looked at an individual flower under a jeweler's loupe or a dissecting microscope?

The minute details of the flower structures could help determine whether it is or is not Bulb. armeniacum.

Flower color within a species can be variable depending on where the plant comes from within the species' range.

The labellum can have what is called a callus which is located further up the lip and closest to the column. The callus may have ridges, appendages, or dentition. These are what separates one species from another most of the times.

Check out how many lobes does the labellum have on it, if there are any.

Is the lip fixed or hinged?

Take into consideration the physical characteristics of the petals and sepals too.

Then there's the column.

Do the flowers have an odor or not?

There's a whole host of terminology about describing orchid anatomy, that I'm not too familiar with. Try looking those up too.

Hope this was somewhat helpful.
