Most aerial roots directly absorb the moisture from fog or humid air. Some surprising results in studies on aerial roots of orchids show that the velamen (the white spongy envelope of the aerial roots), are actually totally waterproof, preventing water loss but not allowing any water in. Once reaching and touching a surface, the velamen is not ...
For so-called "aerial" species (the majority of the common species in culture except Tillandsia cyanea), that is to say those whose roots are transformed into crampons without any power of absorption, watering is done by the leaves in the form of frequent sprays, or brief soaking of the plant in a container full of water.

Dioscorea bulbifera (commonly known as the air potato, air yam, bitter yam, cheeky yam, potato yam, [2] aerial yam, [3] and parsnip yam [4]) is a species of true yam in the yam family, Dioscoreaceae. It is native to Africa, Asia and northern Australia. [ 1 ]
Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. [1] It allows geologists to analyze the distinguishing geological features and structures , plant cover , past history of the site, soil properties, and topography of the study area.
Ficus religiosa taken in early winter Typical example of aerial roots. Ficus religiosa is grown by specialty tree plant nurseries for use as an ornamental tree, in gardens and parks in tropical and subtropical climates. Peepul trees are native to Indian subcontinent and thrive in hot, humid weather.
The plant then grows as an epiphyte. Once it has reached a sufficient size and age, it will begin producing aerial roots that grow toward the forest floor. Once they reach the forest floor, nutrients can be obtained directly from the soil. In this manner, the plant's strategy is to obtain light early in its life at the expense of nutrients.
A plant cuticle is a protecting film covering the outermost skin layer of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no periderm. The film consists of lipid and hydrocarbon polymers infused with wax, and is synthesized exclusively by the epidermal cells.
Grapevine tendrils and leaves. Thorns. Cladodes. Aerial stem modifications are modifications to the aerial stems, [1] vegetative buds and floral buds of plants growing in different conditions and which perform functions such as climbing, protection, support, synthesis of food, or vegetative propagation.
