Poa pratensis, commonly known as Kentucky Bluegrass, Smooth Meadow-grass, or Common Meadow-grass, is a perennial species of grass native to Europe, Asia, North America, and northern Africa.
Poa pratensis is a herbaceous perennial plant 30–70 centimetres (12–28 in) tall. The leaves have boat-shaped tips, narrowly-linear, up to 20 centimetres (8 in) long and 3–5 millimetres (0.12–0.20 in) broad, smooth or slightly roughened, with a rounded to truncate ligule 1–2 millimetres (0.039–0.079 in) long. The conical panicle is 5–20 centimetres (2–8 in) long, with 3 to 5 branches in the basal whorls; the oval spikelets are 3–6 millimetres (0.12–0.24 in) long with 2 to 5 florets, and are purplish-green or grey. They are in flower from May to July, compared to Annual Meadowgrass (Poa annua) which is in flower for eight months of the year. Poa pratensis has a fairly prominent mid vein [center of the blade]
The ligule is extremely short and square ended, making a contrast with Annual Meadowgrass (Poa annua) and Rough Meadowgrass (Poa trivialis) in which it is silvery and pointed. The Kentucky bluegrass is a dark green compared to the apple green color of poa annua and poa trivialis.

Common grass in Kashmir on mountain slopes and forest areas. Photographed from Gulmarg in June, 2010.

This is Poa pratensis

Thanks for correction … What about these two from Delhi?

The first three photographs were from Gulmarg, which I think you are right should be Poa pratensis.
The photographs uploaded Delhi above, and three places in Srinagar at lower altitudes (I am attaching here) I hope belong to S. halepense. Pl. give your verdict.

Yes. The three are S. halepense
