Neck stiffness, stiff neck and nuchal rigidity are terms often used interchangeably to describe the medical condition when one experiences discomfort or pain when trying to turn, move, or flex the neck. Possible causes include muscle strain or sprain, cervical spine disorder, meningitis, and subarachnoid hemorrhage.[1][2][3][4][5][6]
Nuchal rigidity due to irritation of the lining of the brain and spinal cord is one of the main symptoms of meningitis. Also known as Hangman’s Noose.

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.
