Mathews Tuya is a tuya in northcentral British Columbia.[1] It is one of the six tuyas close to Tuya Lake. It has been partly glaciated and Ar-Ar geochronology shows that is it about 730,000 years old. It mainly comprises palagonitized tephra (tuff, lapilli tuff, tuff-breccia) but also has a few dykes and jointed lava flows on its flanks. The top still has flat-lying lava flows erupted after the tephra pile grew above the surface of the enclosing lake. The other volcanoes in the area include Tuya Butte, South Tuya and Ash Mountain. The volcanoes in the region form part of the Northern Cordilleran Volcanic Province.

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.
