A monophthong (/ˈmɒnəfθɒŋ, ˈmɒnəp-/ MON-əf-thong, MON-əp-; from Ancient Greek μονόφθογγος (monóphthongos) 'one sound',[1] from μόνος (mónos) 'single', and φθόγγος (phthóngos) 'sound') is a pure vowel sound, one whose articulation at only beginning and end is relatively fixed, and which does not glide up or down towards a new position of articulation. The monophthongs can be contrasted with diphthongs, where the vowel quality changes within the same syllable, and hiatus, where two vowels are next to each other in different syllables. A vowel sound whose quality does not change over the duration of the vowel is called a pure vowel.
Sound changes[edit]
The conversions of monophthongs to diphthongs (diphthongization), and of diphthongs to monophthongs (monophthongization), are major elements of language change and are likely the cause of further changes.
In some languages, due to monophthongization, graphemes that originally represented diphthongs now represent monophthongs.

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.
