I was thinking desert parsley, but isn't that something else?

There are dozens of desert parsleys, so yes, it's "something else," but it's also this.

Looks like Lomatium klickitatense, which was recently split from L. grayi. (The former L. grayi in the PNW that that are not klickitatense are now L. papilioniferum.)

I see. There are oceans of this stuff in the east gorge flower zones, but a lot of the columbiana too. I suppose the name klickitatense implies that it is endemic to the area.

Yeah, it mostly grows in Klickitat County, with a few adventurous plants across the river in Hood River and Wasco Counties.

I was in Klickitat Canyon yesterday, and it was EVERYWHERE on the slopes above and below the main road.

Aargh! Another split! Are the distributions of klickitatense and papilioniferum mutually exclusive?

Nope! You can find both of them at places like Catherine Creek and Rowena Plateau. But once you get a few miles south of the Columbia, it's all papilioniferum. You can get all the gory details here: https://www.academia.edu/38222634/


In full-grown plants, it's actually pretty easy to tell them apart by the lengths of the leaflets.
