Type locality: "In Virginia." The species was founded upon a plant, described 

 by Gronovius. 



Distribution: Maryland and Virginia, southward to North Carolina, westward to 

 eastern Texas, Oklahoma, and southeastern Kansas.

3. Cynthia falcata sp. no v. 



A perennial plant 40 to 50 cm. high; basal leaves erect, oblong in outline, acutish, 

 glaucous, pinnatifid toward the base, the segments linear, ascending or divergent: 

 leaves on slender, narrowly winged, purplish petioles; stem stout, strongly striate, 

 purplish, bearing an oblong, acute, purplish leaf about the middle, this obtuse or 

 clasping at the base, aquiline-serrate (that is, with falcate teeth directed forward); 

 peduncles several, naked or bracted at the base, the bracts when present entire; 

 peduncles short, strongly hispid just below the heads; involucral bracts 15 to 18, 

 about 1 cm. long; fruit as in C. virginica, with tawny pappus several times as long 

 as the achene. 



Type in the U. S. National Herbarium, no. 415971, collected at Turin, Michigan, 

 June 21, 1901, by Bronson Barlow. A very different plant from C. virginica, readily 

 distinguished by the peculiar toothing of its leaves.

Type locality: "In Virginia, Canada." 



Krigia integrifolia Raf. I take to be this species, although one can not be certain 

 from the description. It came from "Mte. Alleghanies." Cynthia griffithsii Nutt. 

 Beems to belong here, but Nuttall thought it very different from his Hyoseris amplcxi- 

 caulis. 



Distribution: Pennsylvania and New Jersey Bouth to North Carolina, westward 

 to Minnesota, Missouri, eastern Kansas, and eastern Texas. 



Cynthia virginica seems to be a polymorphic species, and it is very possible that; 

 some of these supposed synonyms must at some time be restored or new names given 

 to various segregates. The plant of North Carolina, Georgia, and Tennessee is notable 

 because of its large size, vigorous habit, and large leaves and heads. Its peduncles 

 are always hispid just below the heads. The form found in Pennsylvania and New 

 Jersey is marked by its numerous leaves and glabrous peduncles. The most common 

 form is a plant with inconspicuous cauline leaves, of rather low stature, and with 

 glabrous peduncles. It is the form common through the central part of the range 

 from Virginia westward. Two specimens, one from northern Ohio and one from the 

 Mammoth Cave, Kentucky, attract one's attention because of their long, narrow, 

 entire basal leaves. The Minnesota form is characterized by its much-branched
