Kenyte is a type of igneous rock. More specifically, it is a variety of porphyritic phonolite or trachyte with rhomb-shaped phenocrysts of anorthoclase with variable amounts of olivine and augite in a glassy matrix; the glass may be devitrified.[1]
It was originally described and named by J. W. Gregory in 1900 for the occurrence on Mount Kenya.[2][3] Kenyte has also been reported from Mount Kilimanjaro (Tanzania) and Mount Erebus (Antarctica).[4]

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.
