Lychnis Caryophyllaceae 449 



may safely be ignored. It did occur, no doubt, in the northwestern part 

 of the state but possibly not near Lake Michigan.

no. 225, p. 1046.) L. Coronaria. 



Plants not white-woolly all over; calyx teeth not twisted. 



Flowers scarlet, many, in terminal clusters, opening in the morning; stem rough- 

 pubescent, erect, simple, or little branched; capsule on a stipe about as long as

2502. DIANTHUS L. Pink 



Plants more or less pubescent throughout; leaves linear; bracts 2; annuals 



1. D. Armeria. 



Plants glabrous, or the margins of the leaves and bracts ciliate; bracts 4; perennials. 



Leaves linear, 1-nerved; plants tufted, 2- or 3-flowered (the hardy, named garden 



pinks are derived from this species.) (See excluded species no. 227, p. 1046.) 



D. plumarius . 



Leaves lanceolate to ovate-lanceolate; stems erect, simple, or branched only above; 



flowers in dense, cymose clusters. (See excluded species no. 226, p. 1046.) 



D. barbatus. 



1. Dianthus Armeria L. Deptford Pink. Map 925. Our only report 

 is by Nieuwland from St. Joseph County. I have found it well established 

 in several of the southern counties along roadsides and in pastures and 

 logging roads in woodland.

2503. SAPONARIA L. 



Leaves tapering at the base, sessile or short-petioled; calyx terete; flowers in rather 

 dense, terminal and axillary clusters 1. S. officinalis. 



Leaves rounded at the base, clasping; calyx strongly 5-winged; flowers in a loose corym- 

 bose cyme 2 - S. Vaccaria. 



1. Saponaria officinalis L. Bouncing-bet. Map 926. This species 

 prefers a very sandy soil in which it migrates rapidly. Found throughout 

 the state along roadsides, railroads, and spillbanks of dredged ditches and 

 in waste places and fallow fields. This perennial should be regarded as an 

 obnoxious weed in the parts of the state where there is a sandy soil. 



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



2. Saponaria Vaccaria L. Cow Soapwort. Map 927. This species has 

 been reported from 9 counties. My specimens are from a roadside and the
