This is Dendrobium unicum, a delightful plant with thin, longish canes (up to about 8") and these fascinating flowers. The lip is tubular, cream with burgundy veins. The petals and sepals are reflexed and a vibrant orange. What makes this little guy even cooler is the scent. It smells sort of peachy-apricotty, which just seems to fit perfectly with the color combination.
I'll have to attempt to get better pictures, if it's still blooming, outside when it quits raining.
