Roots of
Voyria aphylla are generally hairless. However, in close contact to roots of
neighbouring plants it develops root hairs, so enhancing the contact surface.
Interestingly, the mycorrhizal fungus almost exclusively enters the V. aphylla
root via this root to root attachments, building a direct hyphal bridge. The root hairs
often are the receiving structure. More information on Voyria aphylla here.
