Ascending Ram's Head Cactus thrive in the desert environment on Ram's Head Desert plants tend to lose their leaves or turn them into spines, reduce surface area, create very waxy leaves to prevent water loss, grow pubescence (very small hairs) which help retain water, and their stomates are in pits to further reduce water loss.
