| Anatomical terminology | |
The preauricular deep parotid lymph nodes (anterior auricular glands or preauricular glands), from one to three in number, lie immediately in front of the tragus.
Their afferents drain multiple surfaces, most of which are lateral in origin. A specific example would be the lateral portions of the eye's bulbar and palpebral conjunctiva as well as the skin adjacent to the ear within the temporal region. The efferents of these nodes pass to the superior deep cervical glands.
The preauricular nodes glands will present with marked swelling in viral conjunctivitis.[1]

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.
