An excellent magnetite specimen from Cerro Huanaquino. Typically the Magnetite specimens from this locality are closely grown together, but these are rarely seen isolated octahedrons, only found in about 5% of specimens. These are also some of the finest quality crystals I've seen from this locality in a few years. The piece has fine, good size, razor sharp, lustrous, black, metallic, "Alpine-type" octahedra measuring up to 1.8 cm across, which is well above average from the locality. They are associated with several small octahedra and tiny cream colored Feldspar crystals on matrix. Virtually all of the crystals are undamaged.

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.
