1919] Long,— American Occurrence of Crepis biennis 213 
technical characters of C. Nicacensis. They certainly do not represent 
C. biennis. The Michigan basis rests upon a sheet of two specimens, 
labelled: “Herbarium, Agricultural College, Mich. Crepis biennis L. 
In meadow on the College farm seeded with orchard grass seed im- 
ported from France. Coll. C. F. Wheeler, 15- VI-97." These again 
apparently represent C. NicaeensisA 
The material from the Missouri Botanical Garden, loaned me 
through the kindness of Dr. Greenman, showed no specimens of the 
desired species; but that from the National Herbarium, generously 
sent me by Mr. Standley for examination, produced a specimen from a 
new locality, This is labelled as collected at Asheville, North Caro- 
lina in 1888 by Gerald McCarthy. The specimen is a nearly complete 
plant in full flower showing the characteristic large heads of the 
species. As an indication of the size and general appearance of the 
expanded heads it is interesting to note that the original label reads: 
"Cynthia virginica” — which, however, has been crossed out and 
“Crepis biennis” written above in pencil. 
In the general search for records of a definite occurrence of Crepis 
biennis it was noted that in Piper and Beattie’s Flora of the Northwest ` 
Coast this species is reported from Vancouver Island on authority of 
Macoun.? A specimen collected by John Macoun and so named has 
been seen from Vancouver Island in the United States National 
Herbarium. Similar material, collected at a later date and then 
named Crepis virens by Macoun, is contained in the Herbarium of the 
Missouri Botanical Garden. Superficially, in habit, leaf-shape and 
generally hispid character, these plants suggest in some measure a 
reduced Crepis biennis, but the technical characters of glabrous inner 
faces of the involucral bracts and generally 10-ribbed achenes, coupled 
with the smaller size of the heads and of the achenes, show that 
they represent further American material of what appears to be C. 
Nicaeensis. 
It is quite possible of course that continued search in the herbariums 
of the country might reveal a few more specimens of authentic C. 
biennis, but when the large collections already examined were able to 
1 [t is pertinent to note that Rouy in the Flore de France indicates that the species is intro- 
duced with lucernes throughout Central Europe, Great Britain, Denmark and southern Sweden. 
One cannot but speculate whether C. Nicaeensis has not arrived in this country in a similar 
way and is to be classed with the various other European species that, as waifs, are picked up 
usually in clover-, alfalfa-, or grain-fields, or grass-lands.
