Needle Peak is the local nickname for the Sierra Aguja in Brewster County, Texas, a small range near the Mexican border and just west of Big Bend National Park. Not to be confused with Needle Peak in Presidio County, Texas, about 17 miles away.
The Needle Peak slopes in Brewster County are noted as a source of quartz crystals, including green moss agate, botryoidal geodes,[1] Needle Peak sagenite, and pompom agates.[2]

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.
