The soil preference of this plant is not clear. It grows in both dry and wet soil. 

 While the dry-soil stations of the Cayuga Lake Basin are probably neutral or acid, 

 the bog stations are all on marl or in highly calcareous localities. 



2. A. SERPYLLIFOLIA L. ThYME-LEAVED SANDWORT. 



A weed in sandy or gravelly cultivated fields and waste places, if not too calcareous ; 

 common. May-Dec. 



Nearly throughout N. A., except in the extreme North. Naturalized from Eurasia. 



Variable; the more slender forms have been called var. tcmtior Mert. & Koch 

 (A. leptoclados of Gray's Man., ed. 7). 



5. Stellaria L. 



a. Plant glabrous. 



b. Bracts foliaceous. 1. S. borealis 



b. Bracts scale-like, scarious-margined. 

 c. Leaves linear ; stem often rough-angled ; seeds smooth ; inflorescence soon 

 becoming lateral. 2. S. longifolia 



c. Leaves lanceolate ; stem smooth ; seeds rough ; inflorescence more ample and 

 more commonly appearing terminal. 3. S. graminea 



a. Plant hairy in lines. 



b. Leaves linear; petals much exceeding the calyx, not deeply lobed. [S. Holostca] 

 b. Leaves ovate ; petals not exceeding the calyx, deeply lobed. 4. S. media 



1. S. borealis Bigel. 



Springy mossy places, with little reference to lime content of the soil though 

 many of the local stations are calcareous ; infrequent. June. 



Hillside n. of station, North Spencer; e. bank of Michigan Creek; Michigan 

 Hollow Swamp; s. e. of Brookton; South Hill (D.) ; Mud Creek, Freeville; Free- 

 ville Bog; McLean Bogs; Beaver Brook (D.) ; swamp, West Dryden; arbor vitae 

 swamp e. of Clyde. 



Newf. and Lab. to Alaska, southw. to n. N. J., Pa., Mich., Minn., Colo., and 

 Calif.; infrequent or rare on the Atlantic Coastal Plain. Found also in Furasia. 



Several varieties are recognized by Fernald (Rhodora 16:150. 1914), of which 

 three are found in the Cayuga Lake Basin — the typical form, the var. isophylla 

 Fernald, and the var. floribunda Fernald. The differences, however, are very slight, 

 and such as might readily be due to environment. These tendencies seem scarcely 

 sufficient to make the forms worthy of varietal rank. 



2. S. longifolia Muhl. 



Damp or wet grassy places, in sandy or gravelly but somewhat mucky, mostly 

 neutral, soils ; frequent. May 20- July 10. 



Michigan Hollow Swamp; Brookton Springs (D.) ; above Enfield Falls and in the 

 ravine ; mouth of Lick Brook ; Larch Meadow ; n. of Coy Glen ; s. of Mecklenburg ; 

 Parkway, Cayuga Heights; formerly on C. U. campus (D.) ; Indian Spring marsh 

 (D.) ; Freeville (D.\) ; Mud Creek, Freeville; McLean Bogs; Beaver Brook (£>.) ; 

 Spring Lake. 



Newf. to Alaska, southw. to Md., Ky., and La., the Rocky Mts., and B. C. ; occurs 

 sparingly on the Atlantic Coastal Plain. 



3. S. GRAMINEA L. 



Damp grassy places, in gravelly or sandy soils ; scarce. June-July. 



On the Chi Psi (Fiske) grounds, 1885 (£>.) ; South and East Aves., C. U. 

 campus; above Forest Home; Ringwood; Cayuga Heights; Myers Point; Kidders; 

 n. of Mud Pond, Conquest. 



Newf. to Ont., southw. to Md. Naturalized from Eurasia.
