18 MINNESOTA BOTANICAL STUDIES. 



Solanum triflorum Nutt. Gen. 1 : 128. 1818. 



Not previously reported from Minnesota. 

 Collected near Sabin, Clay county, Minn. {Miss Ida M. Piper, 

 June, 1891). 



Teronica serpyllifolia Linn. Spec. 15. 1753. 



Not previously reported from Minnesota. 

 Ditches and roadsides near Knife river and Two Harbors, 

 Minn. (E. P. S., June, 1893). 



Lonicera caerulea Linn. Spec. 174. 1753. 



Not previously reported from Minnesota, but collected at 

 Port Arthur, Canada, by Dr. John Macoun. In a bog near 

 Highland, St. Louis county, Minn. {E. P. S., June, 1893). 



Aster longulus n. sp. (Plate 11). 



Stem strict, branching above, 2 — 5 feet high, hispid with 

 jointed hairs; leaves linear, 1 — 4 inches in length, sessile, the 

 cauline with auriculate-clasping insertion, scabrous above, but 

 smooth beneatb, margins scabrous-ciliolate; heads open panicu- 

 late, small, i — i inches in height, singly terminating the erect 

 or slightly spreading branches; involucre 2 — 2^ lines high; 

 bracts linear, loose, approximately equal, outer herbaceous; 

 rays ^ inch in length, lilac-purple to white; achenes compressed, 

 3 — 5 nerved, slightly pubescent when young as in^.s^e?* puniceus 

 Linn. 



The auriculate-clasping cauline leaves and loose, herbaceous 

 involucral bracts of this plant seem to suggest its relationship 

 to Aster tardiflorus Linn, and Aster puniceus Linn., but in aspect 

 it most nearly resembles Aster longifolius Lam. 



It was found in low swampy ground near Milaca, Mille Lacs 

 county, Minn. {E. P. S., July, 1892), and in marshy grounds by 

 roadsides near Center City, Chisago county, Minn. (B. C. Tay- 

 lor, August, 1892).
