In a nutshell they are for texture, moisture, and to provide organic material. Many Paphs grow in rocky (often limestone) outcroppings in pockets of decaying leaf litter. The sand will hold moisture at the hairy roots, the oak leaves open the texture a little and simulates the leaf litter they'd find in nature.
