Trisetum spicatum is a species of grass known by the common name spike trisetum.

 
It is native to North America, Eurasia, and South America. In North America it occurs throughout northern regions, including northern sections of the United States and most all of Canada, its range continuing to Greenland. It is widespread throughout the Canadian Arctic Islands.[1]
 
The grass occurs in a variety of Arctic and alpine habitat types, as well as many types of mountainous habitat in regions farther south.
 
It is a perennial grass forming clumps of erect stems ranging in height from just a few centimeters to over one meter. The narrow leaves are mostly located around the bases of the densely clumped stems. The inflorescence is a narrow spike a few centimeters long or up to 30 to 50 centimeters in maximum length. The spikes are green to purple or brownish and shiny.

This is Trisetum spicatum, one of the highest altitude grass found upto above 5000m in the Himalayas.


Mine from Apharwat Kashmir, alt. 3400 m collected in 1974


I remember it from your photo in your article ‘The alpine grass cover of Uttaranchal’ in ‘Alpine Meadows of Uttarakhand” by Dr G.S.Rawat. Though the TP was printed from wrong side as I can see now in your picture. Thank you for reminding those formidable heights of higher Himalaya. This year hoping to trek to Barjikang Pass in July/August


Pl. do announce when you think of making the trip. Some of us may like to join. Also I have in mind to visit Ladakh after a gap of nearly 40 years, and take photographs of plants which i have only in Herbarium form. Let us see how things evolve. You may suggest appropriate route.
