1923] Fernald,— The Native Tansy of Newfoundland 13 
14 inch in diameter throughout the entire length and had penetrated 
the soil in a vertical direction. 
We did not find any seedlings and the plant seems not to be spread- 
ing by seeds but the colony is increasing in diameter by the under- 
ground roots. Many rosettes of young plants were found over the 
area and particularly around the outer edge. 
Observations of the colony leads us to believe that the plant will 
become a very noxious weed if allowed to spread. Failure to spread 
by seeds may be due to the fact that the plant has been cut before the 
seeds were mature enough to grow or it may be that viable seeds do 
not form in its new habitat. These facts have not as yet been deter- 
mined. There is no doubt, however, that it is able to spread and 
persist by its deep perennial roots. 
The plant is a native of southern and middle Europe and parts of 
Asia and has been found in Argentina and Costa Rica but so far as 
we can find out it has never before been found growing in the United 
States. 
Casually the plant would probably be mistaken for wild carrot. 
The leaves, however, are so different from the lace-like leaf of wild 
carrot that there is no difficulty in distinguishing it from that plant. 
The leaves are ternately pinnate, glaucescent, the leaflets are 
linear-lanceolate, decurrent, finely and irregularly serrate, the teeth 
terminated by a sharp cartilaginous point, the middle leaflet is gen- 
erally divided into three equal decurrent parts or leaflets, the lateral 
leaflets are irregularly divided into one to three parts or leaflets. 
The root leaves are long-petioled, while those on the stem have 
short inflated petioles. The umbels are many-rayed with both 
involucres and involucels of small, narrow bracts. The flowers are 
small with a five-toothed calyx and white incurved petals. The 
fruit (not mature) is oblong with widely diverging styles and filiform 
ribs and one oil-tube in each furrow between the ribs.
