Puccinellia nutkaensis

Puccinellia nutkaensis is a species of grass known by the common names Nootka alkaligrass[1] and Alaska alkali grass. It is native to North America from Alaska across northern Canada to Greenland and Nova Scotia, and down to Washington to Oregon to the Central Coast of California.

Description

Puccinellia nutkaensis is a perennial bunchgrass which is quite variable in appearance, taking a petite, clumpy form or growing erect to 90 centimeters in height with robust inflorescences.[2] It sometimes roots at stem nodes that become buried in moist substrate, and forms dense stands.

A species of leafhopper, Macrosteles fascifrons, is associated with this grass in Alaska, remaining on the grass even when it is submerged amid icebergs.[3][4]

Habitat

It is a plant of the coastline in wet areas with rocky, sandy saline soils. A halophyte, the grass is used for revegetation of salt marshes and other habitat in the intertidal zone in Alaska, where it is valuable for its tolerance of heavy inundation in cold saltwater during high tides and storm surges.[3]

gollark: At my school I discovered that they had keyloggers in place and detected some words you typed. By typing some stereotypical terroristy keywords into an empty document (not saving it, obviously). I explained that I had done it randomly and not really expected anything to happen and they just complained about how I had apparently wasted 45 minutes of people's time as they dealt with this grave issue.
gollark: windows good, linux bad
gollark: It can come shipped with a recipe book, and a browser extension to replace "meat" with "EVIL" or something.
gollark: What if we make a Linux distribution *for* vegans?
