In phonetics and phonology, an intervocalic consonant is a consonant that occurs between two vowels.[1]: 158 Intervocalic consonants are often associated with lenition, a phonetic process that causes consonants to weaken and eventually disappear entirely.[citation needed] An example of such a change in English is intervocalic alveolar flapping, a process (especially in North American and Australian English) that, impressionistically speaking, replaces /t/ with /d/. For example, "metal" is pronounced [mɛɾl]; "batter" sounds like ['bæ.ɾɚ]. (More precisely, both /t/ and /d/ are pronounced as the alveolar tap [ɾ].) In North American English, the weakening is variable across word boundaries, such that the /t/ of "see you tomorrow" might be pronounced as either [ɾ] or [tʰ].[1]: 96 Some languages have intervocalic-weakening processes fully active word-internally and in connected discourse. For example, in Spanish, /d/ is regularly pronounced like [ð] in the words "todo" [ˈtoðo] (meaning "all") and "la duna [laˈðuna]", meaning "the dune" (but [ˈduna] if the word is pronounced alone).[citation needed]

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.
