In the Cayuga Lake Basin this species apparently always occurs in calcareous 

 places, never on the moor of acid bogs. This is strange, as in New Jersey and else- 

 where along the coast it is common in the cedar swamps. The influencing factor may 

 be that of available nitrogen. 



2. D. longifolia L. (D. intermedia, var. americana, of Cayuga Fl.) Sundew. 



Acid peat bogs, in sandy regions ; rare. July 10-Aug. 



Junius peat bogs (Sartwell, D. !), abundant some years. 



Newf. along the coast to Fla. and La., locally in the Great Lakes region. A plant 

 primarily of the sandy Coastal Plain. Found also in Eu. and the W. I.

1. Penthorum (Gronov.) L. 

 1. P. sedoides L. Ditch Stonecrop. 



Low open grounds, usually in mucky soils ; common. July-Aug.

 less frequent there. 



2. Sedum (Tourn.) L. 



a. Leaves nearly terete, small, ovate; flowers yellow. 1. S. acre 



a. Leaves flat and broad. 



b. Plant low and forking ; flowers white, secund on the branches ; leaves obovate, 



entire, the lower ones whorled. 2. 6". ternatum 



b. Plant taller, not forking; flowers paniculate or corymbose, not secund; leaves 

 toothed, all scattered. 

 c. Flowers purple, perfect ; stems 4-7 dm. high ; leaves elliptic-ovate, con- 

 spicuously toothed ; carpels loosely spreading. 3. S. triphyllum 

 c. Flowers greenish yellow or purplish, dioecious ; stems 1-2.5 dm. high ; leaves 

 oblanceolate-cuneate, obscurely toothed near the subacute apex ; carpels

1. S. acre L. Mossy Stonecrop. 



Dry gravelly or sandy roadsides and waste places, and on rocky banks ; scarce. 

 June 20-July. 



Sparingly escaped from cultivation: near the "Nook" (D. in C. U. Herb.); 

 Ithaca Falls (£>.) ; roadside by Willow Glen Cemetery, Dryden; "Kidder's Ferry, 

 rather abund. by the road" (D.) ; gravel pit, Butler village (A. H. Wright & others). 



N. S. to Ont, southw. to Va. and N. Y. Adventive from Eurasia. 



2. S. TERNATUM Michx. 



Gravelly or rocky banks by streams, probably in slightly calcareous soils ; scarce, 

 but locally abundant. May 10-June 10. 



Six Mile Creek, in the Narrows with Camptosorus (/. T. Duncan, 1870, according 

 to Dr. Jordan, D.) ; " abundant in the ravine of the Ferris brook where it is probably

 by Barnes Hall ; cemetery, University Ave., n. e. of the tool house.

 Doubtfully indigenous in cent. N. Y. Even in Six Mile Creek it may have been
