Vergilov Ridge (Bulgarian: Вергилов хребет, 'Vergilov Hrebet' \ver-'gi-lov 'hre-bet\) is a submarine ridge in South Bay, Livingston Island in the South Shetland Islands, Antarctica. It extends 3.5 km in a southeast-northwest direction between the Vergilov Rocks and the opposite Pimpirev Beach at a depth of over 50 m, with depths exceeding 100 m on both sides of the ridge. It was formed as a frontal moraine of Perunika Glacier between the 13th and 17th centuries.
The feature takes its name from the Vergilov Rocks.

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.
