A COLOR FORM OF CARUM CARVI. 
ALBERT HaNronp Moore. 
In July, 1903, Prof. Arthur Stanley Pease and the writer made a 
short botanical excursion to northern Maine and Quebec. "То those 
who have never been in this delightful region, it may be of interest to 
state that not merely the native flora, but also the introduced flora, 
differs very much from our own. Among the weeds common there 
which are not so abundant with us none are more conspicuous than 
Vicia Cracca L. and Carum Carvi L. The former lines the railroads 
with an almost solid strip of blue for long distances, while the other, 
which is only an occasional dooryard escape here, grows profusely 
in the fields and meadows and appears to take the place of our Queen 
Anne’s Lace. The analogy to this plant seems even closer when we 
note that both show an occasional tendency to bear rose-tinted flowers. 
Dr. Millspaugh, in his Flora of West Virginia, 369 (1892), described 
Daucus Carota L. f. rosea Millsp. No name could be found for the 
rose-colored form of the Caraway, although a number of European 
and American floras refer to it. Lange, Haandb. Dansk Flora, ed. I, 
174 (1851), describes Carum Carvi L. 8. atrorubens as having purple 
corolla and leaf-sheaths. A figure of it in the Flora Danica shows 
purple flowers. I was at first uncertain whether this phase might not 
vary so little and so imperceptibly from the rose-colored form that the 
latter would not be worthy of separation. I am greatly indebted to 
Dr. С. Н. Ostenfeld of Copenhagen for clearing my doubts on this 
matter. He states that the form with light rose flowers is much more 
common in Denmark than the other, enclosing, at the same time, 
some of the flowers of Carum Carvi L. var. atrorubens Lange, which 
prove its distinctness. Не also very kindly informs me that he does 
not know of any name for the rose-colored form, the floras merely 
saying, "flowers white or rose," or only “white.” It seems appropriate 
to supply this lack, so I subjoin the following name and diagnosis: 
Савом Carvi L. f. rhodochranthum А. H. Moore, f. nov. floribus 
roseis. Type specimen: QUEBEC, 'l'emiscouata County, St. Louis, 
July 9, 1903 (А. Н. Moore, no. 1218, in Herb. Moore).
