The common and widespread Salix arctica is conspicuous because of its long upright catkins and gray-green leaves with attenuate tips. Calamagrostis muiriana is the grass with purplish open panicles.

Arctic willow will is a subalpine to alpine mat-forming subshrub. It is perhaps the most common of the mat-forming willows and has small leaves that are usually just over 10 mm wide and about 10 mm long. The leaf tip is acuminate and the undersurface is light-green compared to the green upper surface. The styles are 1-2 mm long.

Chilean chess, Bromus berteroanus, White Mountains, elevation 1345 m (4405 ft). Native to South America, and debated whether native or introduced in North America, mostly in summer-dry climate zones on both continents. Populations in North America often seem well-integrated into the native vegetation and not invasive.

Galls on leaves of Wyethia mollis. Searching for this on the internet, I found this is probably from the nematode Anguina balsamophila. It can also infect Balsamorrhiza sagittata. Photos here show both leaf surfaces, galls cut open with nematodes visible (under dissecting scope), and nematodes (approx. 1.5 mm long) on millimeter ruler.

I found this minute odd little fellow today on Clover Run in Tucker County. I would have never noticed it if it were not for tying my boot lace. You can see a hemlock needle for size reference. There was one more nearby that was more compact and funnel shaped like it wasn't ready to open up into the flower petal looking form.That photo didn't come out. (8/28/18)
