Poa trivialis; Rough Meadow-grass is a typical Poa species which is quite similar to the Smooth Meadow-grass. It can best be differentiated by the large ligule (very small in the Smooth Meadow-grass). The name "rough" is given because of the tiny bristles that can be felt if one slides fingers (downward) along the stem. The spikelets have only 2-4 flowers. It is also a rather tall grass.
The Rough Meadow-grass grows in well drained moist soils, often manured. It thrives near homesteads and ditches. Very rare in the highlands
The Rough Meadow-grass is a member of the grass family (Poaceae, also known as Gramineae). The Icelandic name of the Rough Meadow-grass is Hásvefgras.
