leaf tendril (child of leaf): A leaf that is slender and coiling and lacks a lamina. Comment: Aids plant in climbing.
leaflet tendril (child of leaflet): A leaflet that is slender and coiling. Comment: Aids plant in climbing.
leaf apex tendril (child of leaf apex): A leaf apex that is slender and coiling. Comment: Aids plant in climbing.
Can add other types of tendrils if they come up or users need them.
