Wilbrand's knee: Inferonasal fibres of the optic nerve which go into the contralateral optic nerve 4 mm before crossing over to the opposite optic tract. A lesion here produces a junctional scotoma in the superior temporal field of the optic nerve opposite the site of injury.[1][2][3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
