Needle and ricegrasses

I wasn't expecting to, but this field season I spent quite a lot of time with various ricegrasses and needlegrasses. It started with an interest in Henderson's ricegrass in scablands in the Ochoco Mountains, which led to looking for Wallowa ricegrass also in the Ochocos. Looking for rare ricegrasses is a great way to avoid close contact with other humans. In July, botanists attending my workshop asked for help with needlegrass species so we gave extra empasis to them. We saw Achnatherum nelsonii and lemmonii at our field sites and one of the botanists brought samples of the special rare one in Oregon: A. richardsonii. That led to one of the botanists going back to her forest to look for Achnatherum pinetorum. All that said, I should acknowledge that none of them are Achnatherum anymore. They've been renamed, and are now Eriocoma. Here is a link to the article. Of course, we still have Hesperostipa and Nassella.

Needle-and-thread (Hesperostipa comata)and Indian ricegrass (Eriocoma hymenoides) thrive on sandy soils.
