    Hi William

    If the leaf sheath is not hairy and the spikelets are scabrid. It is possibly Bromus sitchensis.

    Cheers

    Quite possibly Pat - that species I have not yet seen north of Wellington but that is no reason why its not up where William lives. It's not one I know very well either.

    The leaves and culms as depicted by William are clearly not hairy - so that rules out B. lithiobius and B. valdivianus, and on looking more critically at the inflorescence it is not 'drooping' either (a feature of those species).

    Many thanks for the further thoughts - the plot thickens. From photos I've been able to glean off the NZPCN site and elsewhere, what we have (there are in fact three of them, the first of which appeared in the middle of some deschampsia cespitosa and has all but killed it off) is not an obvious match for the suggested bromus types. Maybe I should also post a photo of the foliage en masse, which really is quite impressive and dark green. (Would be very helpful if someone could advise on how to post several photos at once.)

    Hi William

    Try working it through the grass key at http://www.landcareresearch.co.nz/resources/identification/plants/grass-key

    and check the photographs there as well. Colour of the laef can vary depending on its situation.

    Cheers

    Try Schedonorus arundinaceus -

    Many thanks for further replies. I'm liking the look of Schedonorus arundinaceus - the habit looks right. Will check it all on site again at the weekend.

    Not a Bromus. Most likely Schedonorus as Peter suggests
