The number at the end of each entry refers to the position the plant occupies in "Wildflowers of the Columbia Gorge" by Russ Jolley. Plants presceded by an asterik (*) are currently still blooming.

* 31. Prairie Lupine: Lupinus lepidus var. aridus - #301 Occasional
* 32. Hybrid Lupine: Lupinus leucophyllus X sericeus - #378 Fairly Common. (Photos to be added later this week.) Plants on the Oregon side of the river seem to have a more open inflorescence, reminiscent of L. sericeus while those on the Washington side of the river tend to be a much tighter, elongated inflorescence reminiscent of L. leucophyllus. Flower color ranges from white near the Dallesport, hot pink near Avery, to more bluish neary Maryhill.
* 33. Hybrid Lupine: Lupinus leucophyllus X sericeus - One plant in bloom about 1.5 miles west of Biggs, OR. With a key, this would probably key out as Lupinus sericeus, but the banner is too far forward (pretty much the same flower as the hybrid listed above). Like the hybrid above, the upper edge of the keel is curved and comes to a fairly long, tapered point.
