I am from South Africa where these plants come from. They grow in wet mountain regions with bright light and low heat. I have attached a photo of my D Capensis growing in full sun, about 28deg C at the moment and you can notice the leaf tip burn. Soon I will move them into cooler area with less heat. If your plant is D Capensis, move the plant indoors with less light and heat and keep moist. The plant will grow fast with floppy leafs and green in color, but at least it will survive. Then you can easily take leaf cuttings to preserve the plant.
