Manuel Bryennios or Bryennius (Greek: Μανουήλ Βρυέννιος; c. 1275 – c. 1340)[1] was a Byzantine scholar who flourished in Constantinople about 1300 teaching astronomy, mathematics and musical theory.[2] His only surviving work is the Harmonika (Greek: Ἁρμονικά), which is a three-volume codification of Byzantine musical scholarship based on the classical Greek works of Ptolemy, Nicomachus, and the Neopythagorean authors on the numerological theory of music.[2] One of Bryennios's students was Theodore Metochites, the grand logothete during the reign of Emperor Andronikos II Palaiologos (r. 1272–1328).[2] Metochites studied astronomy under Bryennios.[1][2]

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.
