Excuse the tree branch. I cut this green stem off the mother plant which is a magnificent tower of 10 feet (consisting of numerous trunks). It looks very similar to a pencil cactus but its sticks are all upward-pointing and it has a lot of aerial roots (with green tips) like those of an orchid. I've searching for its name for a long time but to no avail. Thank you for reading.
Oh wow! Thank you I did more searches on the net for pics and it appears to be so! So this is an orchid of the vanda family. Gee, I planted it in soil. Think I better have it placed in the usual orchid media.
