The tract (Latin: tractus) is part of the proper of the Christian liturgical celebration of the Eucharist, used instead of the Alleluia in Lent or Septuagesima, in a Requiem Mass, and other penitential occasions, when the joyousness of an Alleluia is deemed inappropriate. Tracts are not, however, necessarily sorrowful.
The name apparently derives from either the drawn-out style of singing or the continuous structure without a refrain. There is evidence, however, that the earliest performances were sung responsorially, and it is probable that these were dropped at an early stage.
In their final form, tracts are a series of psalm verses; rarely a complete psalm, but all the verses are from the same psalm. They are restricted to only two modes, the second and the eighth. The melodies follow centonization patterns more strongly than anywhere else in the repertoire; a typical tract is almost exclusively a succession of such formulas. The cadences are nearly always elaborate melismas. Tracts with multiple verses are some of the longest chants in the Liber Usualis.

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.
