fields and waste places. Along with it, however, I soon began to 
notice a coarser, more bristly plant of the same genus, which I at 
first took for the native C. barbigera Leiberg. But this species, a 
lower and stouter plant, seems to be confined to the sage-brush 
plains of Eastern Oregon, while our plant had every appearance of 
being an immigrant. During the first season I saw but a few speci- 
mens; but each year has added to the number, until it is now almost 
as frequent as C. capillaris, with which it is associated in great abun- 
dance in waste places, fields, roadsides and river-banks throughout 
the entire region adjacent to Salem. Professor C. V. Piper, to whom 
I pointed it out in 1918, informed me that it was C. setosa Haller f., a 
native of that apparent paradise of weeds, the Mediterranean region, 
and that I would not be able to find a description of it in any Ameri- 
can work. The fact that it has not found mention in any Western 
manual shows that it must be of comparatively recent introduction 
and restricted range; but a stranger in Western Oregon would infal- 
libly conclude that it deserved to be enrolled among our most thor- 
oughly established weeds. It would be interesting to know to what 
extent it has been observed by Eastern collectors. As far as C. 
biennis is concerned, my experience here has been identical with Mr. 
Long's. I have never seen the plant, or anything like it. Macoun's 
material from Vancouver Island is probably the basis for Henry's 
inclusion of the species in his recent Flora of Southern British Col- 
umbia, 329 (1915); but Mr. Long has shown Macoun's plant to be 
C. nicaeensis, and the existence of true C. biennis in the Northwest 
seems still to lack confirmation. Apparently no native species of 
the genus have found their way into the Willamette Valley, although 
C. occidentalis Nutt. and C. monticola Cov. both occur in the south- 
western portion of the State.—J. C. Nerson, Salem, Oregon. 
A FURTHER Nore on CnEPIS BIENNIS.—In a recent article on the 
American occurrence of Crepis biennis! it was shown that most of 
the records for the species were based upon misidentifications, and 
that only three authentic specimens were found in the large collec- 
tions of the Gray Herbarium, the New York Botanical Garden, the 
National Herbarium, the Missouri Botanical Garden, and the Phila- 
delphia Academy. The only data on the occurrence and persistence 
! Long, Ruopora, xxi. 209 (1919).
