I just looked up C. maxima var. Highlands on OrchidWiz to try to find an official picture. Instead, what I discovered is that while there are several varieties listed, Highlands is no where to be found. In other words, your particular orchid is not registered under that name to the best of my knowledge. C. maxima orchids are found in the warm areas of Ecuador, Peru and Colombia and also up a ways in the mountains. So, it looks like the "Highlands" name comes from the high growing plants but it is not a registered variety. I also found an article saying the highland growing maximas are hard to cultivate outside of greenhouses because we cannot match their natural growing conditions. I'm not saying that applies to your orchid as I really don't know what variety it is.
