Hawaii 2017; Kauai. visit to Waimea Canyon
Closely related to the famous silversword plants found on Maui's Haleakala volcano Wilkesia gymnoxiphium (Hawaiian iliau) is endemic to the island of Kauaʻi. The iliau, abundant along this short and picturesque nature trail, is one of three genera, with Argyroxiphium (silverswords and greenswords) and Dubautia that are believed to be descendant from a single species related to our 'California' tarweed. Greater than 2,500 miles away over a vast expanse of ocean. Imagine that.
