Since the preceding pages were in print, I have discovered 
that the plant which here appears as EH. Oregonense, var. 
(?) gracillimum, has been published by Professor Hauss- 
knecht in Mittheil. Geogr. Gesellsch. zu Jena, 1888, 
vii. 5, — fide Just, Jahresb. xvi (2), 156—, as #. Prin- 
gleanum, Hausskn, so that it should bear this name.
