Common furnlp. 

 Distribution: 



Introduced from Burope. "$ends to escape from or 

 persist after cultivation, and often Is a noxious weed" 

 (6. H.). It does not seem to be at all dangerous as a 

 weed here* perhaps because the severe winters make sur- 

 vival uncertain; and so with B. oampestrls * 



Pi* Hon. Co.: "Occasionally spontaneous". PI. 

 Buf. ylo.! often from "bird-seed". C* F.: not listed. 

 Loc • Herb . : no specimens • 

 Collected as follows:- 



1. New baseball field. . 



2, 2. Near Chicago (B. of McLean) In two places. 

 There seems to be no room for doubt with No. 1, which Is 

 marktlj hirsute -pubescent at the base. No more than 

 slight traoes of pubescence -^ have been found on No. 2, 

 but these traces » the leaf -form (the basal leaves are 

 gone)> the flowers, the flattened form of the root, and 

 especially the apparently definitely white color of the 

 root when fresh, seem to determine the specimen surely as 

 B« rapa » No. 3, with slender root and all lower leaves 

 gone. Is perhaps less certain, but the petiole of one 

 leaf bears at the base 2 hirsute "prickles" like those 

 found on No. 1.
