Dobrovolʹskiy is a small lunar impact crater on the Moon's far side. The northwest part of its rim is intruded upon by the somewhat larger crater Shirakatsi, and the outer rampart of that feature covers most of the interior floor of Dobrovolʹskiy. Very little of the original floor now survives, with a small section near the southern inner wall. The remainder of the crater rim is somewhat circular and only mildly worn.[2]
To the north the southern rim of the much larger crater Perepelkin is intruded upon by Shirakatsi, and the three form a brief, curving crater chain. To the southeast of Dobrovolʹskiy is the crater Volkov.
In 1973, the crater was named after cosmonaut Georgiy T. Dobrovolskiy, who died during the Soyuz 11 mission.[3]
Satellite craters
[edit]By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Dobrovolʹskiy.

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.
