The wroshyr tree known as the white wroshyr tree was originally native to the planet Kashyyyk. These trees had been extinct for several millennia by approximately 40 BBY. The fossilized amber from this tree formed Meryx, a gemstone considered to be among the most prized in the galaxy. In the time of the High Republic Era, Wookiee Jedi Padawan Burryaga Agaburry possessed a lightsaber with meryx plating.
