The Flora of the Cayuga Lake Basin 141 



Dudley distinguishes certain depauperate specimens on Trumansburg Point, Utt 

 Point, and the Marl Creek Meadows, as var. obtusatus Engelm. ; but abundant mate- 

 rial recently collected in those localities shows nothing sufficiently extreme to be con- 

 sidered that variety, which is of coastal distribution. 



14. J. alpinus Vill., var. fuscescens Fernald. (/. a., var. insignis, of Cayuga Fl.) 

 Gravelly and sandy calcareous shores ; locally abundant. July-Sept. 



Renwick; Taughannock Point (D.\) ; Utt Point (D. !) ; Big Gully Point; Farley 

 Point; between Kidders and Sheldrake; Indian Salt Spring (type station). 



Vt. to B. C. and Mo. 



These plants all belong to this variety, though typical /. alpinus occurs at Tully 

 Lake just outside the basin. Var. fuscescens differs from the typical form in that 

 the numerous heads and branches give a more bushy paniculate or subcorymbose 

 inflorescence, and the heads are usually without scattered, raised, pedicelled flowers. 

 In 1918 there were found on Big Gully Point and in that vicinity very small plants 

 without seed and with an appearance intermediate between that of /. alpinus and that 

 of /. articulatus. These plants may have been hybrids of these two species. 



15. J. canadensis J. Gay. (/. c, var. longicaudatus, of Cayuga Fl.) 

 Calcareous marshes ; frequent. Aug.-Sept. 



Summit Marsh (D. !) ; Lake Como (Locke Pond, D.) ; moor of Junius marl 

 ponds (D. !) ; Crusoe Prairie; Montezuma (D. in C. U. Herb.!) ; near Duck Lake; 

 Spring Lake ; Westbury Prairie. 



Newf. to Minn., southw. to Ga. and La. ; common on the Coastal Plain. 



Near the coast this plant grows in acid bogs or in brackish marshes. Its occur- 

 rence about Cayuga Lake in marl bogs is difficult to explain. This may be due to 

 the traces of salt in the springs of this region, a feature to which is apparently 

 due the presence of other saline plants here. In the Cayuga Lake Basin this species 

 is very variable in size of inflorescence and of heads. 



16. J. brachycephalus (Engelm.) Buch. (/. canadensis, var. brachycephalus, of 

 Cayuga Fl.) 



Marl bogs and springs ; frequent. Aug.-Sept. 



Spencer Lake; near West Danby (D. !) ; w. of Key Hill; s. side of Coy Glen; 

 Larch Meadow; e. of Slaterville (C. U. Herb.) ; Fir Tree Swamp between Slaterville 

 and Dryden; Dryden Lake (£>.!) ; s. of Groton (D.) ; by railroad, e. of McLean; 

 Junius marl ponds (£).!). 



N. Me. to Wis., southw. to Conn., Pa., and 111. ; absent on the Coastal Plain. 



17. J. brevicaudatus (Engelm.) Fernald. 

 Ditches and muddy places ; rare. Aug.-Sept. 



Springy hillside e. of Cayutaville. [Frequent on the highlands of Cortland Co.] 

 Newf. to Minn., southw. to Conn., Pa., and W. Va. ; infrequent on the Coastal 

 Plain. A northern plant, generally found in both acid and subcalcareous soils. 



2. Luzula DC. 



a. Flowers solitary at the tips of the branches of the inflorescence. 1. L. saltuensis 

 a. Flowers in glomerules. 2. L. campestris, 



var. multifiora 



1. L. saltuensis Fernald. (L. pilosa of Cayuga Fl.) Wood Rush. 



Rich wooded banks, mostly in gravelly, more or less calcareous, soils ; not un- 

 common. Apr. 15-May. 



West Danby; hillside beyond Larch Meadow; Six Mile Creek, common; Fall 

 Creek, near Triphammer Falls and e. of Forest Home; and elsewhere.
