Looks very much like my Epidendrum Cinnabarium which I have in both red and yellow. I have heard it referred to as the "up-side-down" orchid, as the lip is up rather than hanging down like other orchids. I knew it also came in orange and yours is beautiful.
These are considered the "weeds" of orchids but I guess I love weeds. My deck is full of all colors and there are loads of flowers at this time of year. I ordered six hybrids a couple of years ago from Santa Barbara Orchids that are fantastic. They do not get the aerial roots that Epi Radicans gets and the stems are huge thick looking canes resembling dendrobiums. One of the plants that is red has two inch flowers in large clusters that continues to elongate and bloom for months. The plants are very carefree because they have no pests or disease problems and I can leave them out year around in Central Florida because they are hardy to 28C. Now tell me what more could you ask of an orchid and they call them "weeds".
