    This is probably either straight P. wallichiana or one of the hybrids with P. strobus...but still worth asking about, because I don't remember seeing one this 'droopy'. Also I measured some of the needles as long as 23 cm/9", which seems long for either of these.

    Looks good for pure P. wallichiana, the only proviso being whether that would be hardy enough to survive the coldest winters there. Any idea what the coldest has been in the last 25-30 years there? Anything below about -25°C in that period?

    A bit odd there's no cones; it is certainly old enough to produce them, and is usually fairly prolific. Worth a look under to see if there's any old ones, they'll help with confirming the identity.

    Thanks Resin! Bean/Grimshaw et al https://www.treesandshrubsonline.org/articles/pinus/pinus-wallichiana/
    say needles up to 7 inches, and conifer.org says up to 20cm. Is it possible this is just one with needles at the longer end of the range?

    Anyhow, it's nice whatever it is.

    I can look for cones next time I'm up there.

    That area would have been around -20C in the polar vortex winter, but not much lower than that in the past 25 years I bet.

    23 cm is unusual, but not impossible, for P. wallichiana. It's certainly nice to have one with needles that long! Sorry, I've not seen any data on whether trees from India or Pakistan have the longest needles.
