For the phals, are you referring the photosynthetic capabilities of the roots? As for the stomata and adaptations to conserve water, those things are general to all plants.
I do remember reading some articles that looked into how much phal's roots contributed to the total photosynthesis of the plant, and how much nutrient intake there was via the leaves. I have the PDFs somewhere....
