nearly all parts of the state. It prefers a moist soil and is locally abundant 

 mostly in fallow fields, pastures, and open woodland along streams. 

 Nat. of Eu. ; throughout temperate N. A. 



2433. SAGINA L. 



1. Sagina decumbens (Ell.) T. & G. (Sagina apetala of Amer. 

 authors.) Pearlwort. Map 905. Local in the southern counties in bare, 

 sandy places in fallow fields and pastures and on the tops of river bluffs. 

 In several instances it was intimately associated with Plantago pusilla. In 

 the fields and pastures it appears as if introduced, and on the bluffs of 

 streams far from fields it appears as if native. The plants are mostly 2-5 

 inches high and erect or erect from a very short, decumbent base and none 

 are apetalous. 



Mass. to 111., and Mo., southw. to Fla. and La. 



2443. ARENARIA L. Sandwort 



Leaves ovate, oval or oblong; capsules longer than the sepals. 



Blades less than 1 cm long, acute at the apex ; seed not smooth 



1. A. serpyllifolia. 



Blades mostly 1-3.5 cm long, generally obtuse at the apex; seed smooth 



2. A. lateriflora. 



Leaves linear or filiform; capsules shorter than the sepals. 



Plants glabrous; leaves fascicled in the axils, rigid 3. A. stricta. 



Plants glandular-pubescent, sometimes sparsely so; leaves not fascicled in the axils, 

 soft 4 - A - patula. 



1. Arenaria serpyllifolia L. Thymeleaf Sandwort. Map 906. In 

 very sandy soil along roadsides and railroads, in fallow fields, and rarely 

 on bare spots on bluffs of streams. Naturalized in Indiana; I believe it 

 could be found in railroad ballast in every county of the state. 



Nat. of Eurasia; throughout N. A. except in the extreme north.
