"wild angraecum"

[D&S Mabel]

I recently purchased a few orchids on Ebay from a seller I had used a few times before and when I received the plants, in amongst them was the one pictured below, labeled "wild angraecum".

I wrote the seller asking about the plant and, because of a language barrier - he is out of Puerto Rico, all the more I could get was it was a "gift" to me (free), that it is from Madagascar, it's a species orchid (not a hybrid) and it has white flowers. ALthough I asked about how to care for it, I got no help there.

For scale, the piece in the picture is about 7" long with the leaves being about 1" long. The roots almost look aerial to me, alot like the vanda terete I have.

I stuck it on the bark raft but I have no idea what is best for it and, with a quick internet search, there appears to be about zillion varieties of angraecum out there. I have an Angraecum Longiscott 'H&R' but this plant doesn't appear to me to be at all like that one.

Any thoughts on more accurately what it is and/or a point in the right direction as to how to care for it would be much appreciated!

Hello D&S Mabel, I was looking at Jay's Internet Orchid Species Photo Encyclopedia Anc-Az and found Angreacum sambiranense, its from madagascar and its warm to hot growing.

There are number of climbing type angraecum species out there. Examples are A. infundibularae, eichlerianum.
Probably warm or intermediate grower.

According to the reference manual Angraecoid Orchids by Stewart, Hermans and Campbell, there are approximately 15 genera and 360 species of Angraecum that come from Madagascar and Africa. There are lots of relatives as well from places such as Sri Lanka. There are approx 32 genera and 330 species of Aerangis and its close relatives (Aerangidinae) from the same locations. With all these, it would be pretty difficult to nail down the genera, let alone species until it blooms. At that point, you'd still be guessing although with proper taxonomy you might do it.

Not all climbing angraecums are warm growing, some 'reedstem angraecums' are cool-cold growing like Angraecum germinyanum.
