Gerrit de Veer (c. 1570–after 1598) was a Dutch officer on Willem Barentsz' second and third voyages of 1595 and 1596 respectively, in search of the Northeast passage.
De Veer kept a diary of the voyages and in 1597, was the first person to observe and record the Novaya Zemlya effect, and the first Westerner to observe hypervitaminosis A caused by consumption of the liver of a polar bear.[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.
