7. D. canadense (L.) DC. 



Open moist gravelly banks, in neutral or somewhat calcareous soils ; common. 

 Aug.-Sept. 



Especially abundant throughout the basin on railroad embankments, gravelly lake 

 shores, and gravelly bars in streams ; elsewhere rare or absent. 



N. B. to Man., southw. to N. C, Okla., and Nebr. ; less frequent on the Coastal 

 Plain. 



[D. rigidum (Ell.) DC. 



Reported by Dudley with the following stations and comments : "Near ravine 

 north of Enfield ravine. Near White Church. A form (possibly a hybrid D. rigi- 

 dum DC. x D. Marilandicum, Boott,) with smoothish stem and leaves 3-4 cm. long, 

 nearly smooth, occurs at White Church." Two specimens sent by Dudley to Wat- 

 son, and now in the Gray Herbarium, are D. Dillenii, with small leaves but other- 

 wise typical of that species ; one bears the label "White Church, 1885, no. 27 b", the 

 other " Near Enfield Falls, 1881, no. 27 a ". D. rigidum is a plant of the Coastal 

 Plain and around the Great Lakes westward, and probably does not occur in central 

 New York.] 



8. D. marilandicum (L.) DC. 



Open dry thickets, in sandy or gravelly noncalcareous soils ; rare. Aug. 



Near White Church (D.) ; Coy Glen (D.\) ; V/ 2 miles s. of Pout Pond, abundant 

 (K. M. W., A. J. E., & L. F. Randolph). 



Mass. to Minn., southw. to Fla., La., and Mo., including the Coastal Plain. 



Dudley lists var. P, T. & G., with larger leaflets, from Fall Creek mill pond and 

 from near White Church. Hybrids of D. marilandicum with some hairy species 

 occur at Coy Glen.
