Kedrosis africana has a stem that is swollen at the base to store water; which type of stem is this 
This tactic is seen in Aloe dichotoma in very dry conditions, where there water supply to a branch is cut off and it drops off 
Stomata in the above close during this time 
The colour of the waxy foliage in Aloe striata to reflect sunlight 
Hoodia gordoni has brown flowers that attract these pollinators 
Aloe distans has high concentrations of these two pigments in the leaves to reflect more sunlight 
Aloe distans has high concentrations of these two pigments in the leaves to reflect more sunlight

Present in leaves of living stones to reflect light to the base as leaves extend into the ground 
Aciacia karoo has large (x) to defend and shade the plant 
Welwitschia mirabilis has fleshy leaves with (x) stomata

Old collapsed trees act as (x) logs as they provide nutrients for growing saplings 
Toxins and poisons are deposited in leaves for expulsion when leaves are lost to reduce water loss in winter in this type of tree
