8. Lysimachia longifolia Pursh. (See Pflanzenfam. IV, 237: 279. 

 1905.) (Steironema quadriflorum (Sims) Hitchc.) Map 1601. Rather 

 frequent in the lake area in marshes and springy areas about lakes and 

 along streams. Farther south it is infrequent to local in springy places. It 

 is sometimes found in wet prairies.

6333. TRIENTALIS [Rupp.] L. 



1. Trientalis borealis Raf. (Rhodora 11: 236. 1909.) (TrientaMs 

 americana (Pers.) Pursh.) Star Flower. Map 1602. In deep humus, 

 usually in tamarack and birch bogs, under white pine in swamps, or in low 

 woods which border the preceding habitats. Local but frequent to common 

 where found.

6338. ANAGALLIS [Tourn.] L. 



1. Anagallis arvensis L. Scarlet Pimpernel. Map 1603. Our speci- 

 mens are from clover, wheat, and abandoned fields, waste places about 

 habitations, and rarely in open places in nearby woods.

6339. CENTUNCULUS [Dill.] L. 



1. Centunculus minimus L. Chaffweed. Map 1604. This plant is 

 usually one and a half to four inches high and so minute as to be easily 

 overlooked. It has been reported from Floyd and Jefferson Counties. 

 Where I have found it, it is always a common to abundant plant. I believe 

 it to be local, however, because of its habitat, for it apparently prefers a 

 minimacid soil. It is found in bare places in open woods, usually associated 

 with black oak, in bare places in pastured woods, along paths in woods, 

 and in abandoned fields.
