Not sure if ‘aerial rootlets’ is the best term here. There are various forms of adventitious roots that could be called ‘aerial’ and whose main function is not for attachment. Like the aerial roots of orchids (often with the velamen radicum) or aroids. Climbing aroids usually have two types of adventitious roots, i.e. anchor roots that are like the ‘aerial rootlets’ in the picture above and feeder roots that are growing down to the ground to access water and nutrients in the soil.
