Generally distributed in the basin where the foregoing conditions obtain ; absent on 

 the richer soils. 



P. E. I. to Ga., mostly in the mts. and along the coast ; rare inland to Ky., Ohio, 

 and Minn. 



3. S. caesia L. 



Dry open woods, in shallow soils of clay, gravel, or mixed clay and gravel ; com- 

 mon. Sept. 5-Oct. IS. 



Generally distributed throughout the basin, but much less frequent in the more 

 sandy acid soils. 



S. Me. to Minn., southw. to Fla., Ark., and Tex.; less common on the Coastal 

 Plain. 



4. S. latifolia L. (S. flexicaulis of many authors, doubtfully of L.) 



Moist or somewhat dry sheltered woods and thickets, in shale talus, shallow gravel, 

 or clay; frequent. Aug. 15-Sept. 10. 



Most abundant about the ravines of the basin, scarce in the more acid sandy soils 

 of the higher hills, and rare or absent on the richer clays and alluviums. 



N. S. and N. B. to S. Dak., southw. to Ga., Tenn., and Kans. ; rare on the Coastal 

 Plain. 



5. S. humilis Pursh. (See Rhodora 17 : 6. 1915. S. uliginosa of Gray's Man., ed. 7, 



and of Cayuga Fl.) 



Boggy calcareous meadows ; scarce. Sept. 



Larch Meadow (D.) ; Mud Creek, Freeville (D.) ; McLean Bogs (D.) ; tamarack 

 swamp n. of Crusoe Lake. 



Newf . to Man., southw. to N. C, Pa., Wis., and Minn. ; rare or absent on the 

 Coastal Plain. 



6. S. uniligulata (DC.) Porter. (S. neglecta, var. linoides, of Cayuga Fl.) 

 Boggy and springy places, usually in marly soil; scarce. Sept.-Oct. 15. 



Mud Pond, McLean Bogs; Newton and Lowery Ponds (D. !) ; Crusoe Prairie; 

 Spring Lake; Westbury Bog. 



Newf. to Ont. and 111., southw. to N. J. and Pa., including the Coastal Plain. 



6a. S. uniligulata (DC.) Porter, var. neglecta (T. & G.) Fernald. (See Rhodora 

 23:292. 1921. S. neglecta of Gray's Man., ed. 7, and of Cayuga Fl.) 



Habitat similar to the preceding; occasional. Aug. 10-Sept. 



Larch Meadow (D. !) ; Mud Creek, Freeville; boggy field, Malloryville; vicinity 

 of McLean Bogs (£>.). 



N. S. to Wis., southw. to Md. and 111., including the Coastal Plain. 



No good specific lines can be drawn between the species and its broader-leaved 

 variety; not even the difference in number of rays seems constant. Plants of this 

 species with narrow panicles are frequently confused with S. humilis. Stations in 

 the Cayuga Lake Basin are all more or less limy, though both this plant and the 

 typical form are at least frequent in the more acid soils of the Coastal Plain. 



7. S. juncea Ait. 



Dry fields and open thickets, in sandy or gravelly, limy or acid, sterile soils ; 

 common. July-Aug. 



Nearly or quite absent on the clays and richer soils of the basin. 



N. B. to Sask., southw. to Ga. and Mo., including the northern Coastal Plain. 



This species and S. serotina begin to flower earlier in this region than do other 

 species of goldenrod.
