A coronal stop is a stop consonant articulated with the front part of the tongue (whence "coronal"). Depending on the precise place of articulation, several types can be distinguished:
- Dental stops, articulated with the tongue touching the upper teeth
- Alveolar stops, articulated with the tongue touching the alveolar ridge behind the upper teeth
- Postalveolar stops, articulated with the tongue touching the back of the alveolar ridge
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.
