A gear case, also known as a chain case or chainguard, is an enclosure for the bicycle chain and sprocket assemblages commonly employed by utility bicycles. It serves to protect the cyclist from being soiled or trapped in the chain rings and tends to fully enclose the drive train. It may also contain an oil bath to keep the chain lubricated. Modern examples are usually moulded in plastic. Similar devices may be found in connection with chains used on larger vehicles and machinery.

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.
