Description

Danthonia decumbens is a perennial plant with a decumbent habit; it lies on the ground with the tips turned upward.

It has narrow, bright green leaves taper to a sharp point and are rather hairy. A long upper leaf sheath clasps the delicate stem. The stem is 15–30 centimetres (5.9–11.8 in) high and slightly bent at the base, smooth with 1 to 3 nodes.

The ligule consists of a ring of hairs, as in the purple moor grass, Molinia caerulea, except that in this plant each end has a tuft of longer hairs.[2]

The panicle consists of 4 or 5 large erect glaucous silvery green or purplish awnless spikelets. These are arranged alternately on the upper part of the stem. The bunchgrass flowers in the summer months.

Ecology

The plant is found on acid pastures and heathland, on sandy or peat soils, which are also often damp.

The grass, having no domestic forage value, is not grown agriculturally.[2]

gollark: And yet we have a mostly functioning system which produces mostly enough food, and is able to make the mind-breakingly complex supply chains for that food work.
gollark: Pretty much everything we actually produce is in the "not entirely necessary but nice to have" box.
gollark: There is lots of stuff which nobody really *needs* - you can live without it, society could work without it (if we had set stuff up that way) - but it's not very nice to not have it. Like computers, or modern medicine, or non-bare-minimum food and housing.
gollark: Food is, broadly speaking, necessary to live. But while I could probably *survive* on cheaper, less resource-intensive-to-produce food than I do, or less food by caloric content and stuff, I like to have more/better food than is strictly necessary. Same with water - I won't die of dehydration on some small amount per day, but on the whole I'll be worse off if I don't have as much to drink as I want, or enough water for showering and washing stuff.
gollark: I'm typing.
