The Flora of the Cayuga Lake Basin 139 



1. J. effusus L., var. solutus Fcrnald & Wiegand. (See Rhodora 12:81. 1910.) 

 Meadows, ditches, and the borders of marshes, in various soils not conspicuously 



calcareous; common. July-Aug. 



Newf. to Wis., southw. to W. Va., including the northern Coastal Plain. 



la. J. effusus L., var. Pylaei (Leharpe) Fernald & Wiegand. 



In situations similar to the preceding, abundant in pastures and springy places, less 

 abundant on the larger marshes but not reported from marly soils; very common. 

 July-Aug. 



Newf. to Wis., southw. to W. Va., including the northern Coastal Plain. 



The flowers vary considerably in size. 



No true var. decipiens Fernald & Wiegand has yet been found in the Cayuga Lake 

 Basin. 



2. J. inflexus L. (See Schinz & Thel., Bui. Herb. Bois., ser. 2, 7:400. 1907. /. 



glaucus Ehrh.) 



Meadows and swales ; locally abundant. July. 



Plats along Spencer St., Ithaca, and near the mouth of Buttermilk Creek, 1922, now 

 rather abundant. 



Native of Eurasia and Africa, and probably adventive at Ithaca. Previously 

 reported from America by House, who collected it at Sangerfield, Oneida Co., N. Y., 

 in 1917 (Rept. N. Y. State Bot. 1921). 



3. J. bufonius L. 



Silty and muddy ditches, roadsides, and shores, often in clay or sand but not in 

 strongly calcareous soils ; common. June 15-July. 



Almost throughout N. A., extending to Lab.; cosmopolitan. 



4. J. Gerardi Loisel. Black Grass. 



Marshy soils, in saline situations ; rare. July 20- Aug. 



Rocky bed of Fall Creek above Forest Home (a very unusual habitat) ; Myers 

 Point (?) ; Union Springs; brackish marshes e. of Montezuma (D. in C. U. Herb.!), 

 probably native. 



Salt marshes along the coast, Newf. to Fla., and on the n. w. Pacific coast ; inland 

 in Me., Vt., N. Y., and about the Great Lakes. Found also in Eurasia and n. 

 Africa. 



Plants (probably introduced) near the salt works at Myers Point agree with this 

 species in the length of bract and anther and in color of perianth, but are more like 

 the species next following in length of perianth and shape of capsule. 



5. J. compressus Jacq. 



In situations similar to tire preceding ; rare. July. 



About the salt works, Ithaca flats (introduced) ; first detected in 1895, since which 

 time it has persisted. These salt works, and also those at Myers, are recent, and 

 did not exist in Dudley's time. /. compressus may have been introduced with sand 

 and other material brought to a glass factory formerly existing near the salt works. 

 It occurs also about the Freeville railroad station. 



Native of Eu. and Asia; heretofore reported in N. A. only from Murray Bay 

 (Eggleston) to Que. (Pease) and w. Newf. (M. L. Fernald & K. M. W.). 



6. J. tenuis Willd. Path Rush. 



Damp or rather dry grassland, most commonly in paths and on roadsides but 



also in waste places and on shores, in very diverse soils; common. June 20-Aug. 10. 



Almost throughout N. A. except in the extreme North ; adventive in Eu. and Af r. 



6a. J. tenuis Willd., var. anthelatus Wiegand. 



Damp pasture lands, in undrained. rather heavy, soil ; rare. July. 



Hill two miles s. e. of Brookton (K. M. W ., A. J. E., & L. F. Randolph) ; n. w. of 

 South Hill Marsh. 



Me. to Mo. and Tex.
