My first thought is Dendrobium farmeri, "Eggs Sunny side up"
later on - thinking about the fairly slender canes in your picture….hmm…..
Glen, how big is the plant? Are those canes really small or are they long? ( if pretty Kitty is a good size comparison, they are not too long) If they are smallish - there is Dendrobium loddigesii? Loddigesii makes eventually creeping mats.
