to it in the Michigan Flora. In the course of botanical work in the eastern 

 part of the Northern Peninsula, from 19 12 to 19 17, the writer found it 

 abundant on damp, open or partially shaded ground on Bois Blanc Island, 

 about St. Ignace, and in all the northern counties from Macinac to Mar- 

 quette inclusive. 



Collinsia parviflora Lindl. 

 Small-flowered Collinsia 



This little plant is given in Gray, and its habitat and range are described 

 as "Rich soil and limy gravel, Ont. N. Mich, and westw." In Britton and 

 Brown it goes by the name of C. tcncUa (Pursh) Piper, and the habitat and 

 range are given as "Moist places, Ontario to British Columbia, Michigan, 

 Colorado, Arizona and Utah." The Michigan Flora mentions only one Mich- 

 igan record, Keweenaw County, observed by O. A. Farwell. Owing to the 

 fact that it is usually only three to six inches long and grows in obscure places 

 it easily escapes observation. In early June; 1917, it was found by Mr. 

 B. Gladewitz and the writer in Marquette County, wdiere it grew in abund- 

 ance in rock cracks and crevices on the summit and sides of a large granitic 

 hill known as Huron Mountain. It is very probably to be found in like places 

 throughout the county. 



Mimulus moschatus Dougl. 

 Musk Ploiucr 



Both Gray and Britton and Brown give Michigan in the range of this 

 plant and intimate that perhaps it has been introduced from the west. In 

 the Michigan Flora it is mentioned as having been observed by O. xA.. Far- 

 well in Keweenaw County. The writer found it plentiful about Grand 

 Marais in Alger County in 1916, where it occurs in damp places mostly along 

 roads but also in other damp open spots. It may have been introduced. 



Digitalis purpurea L. 



Purple Foxglove 



Both Gray and Britton and Brown substantially agree that this plant is 

 "naturalized from Europe, sparingly escaped from cultivation." It is not 

 only cultivated as an ornamental plant but it is a valuable and much used 

 drug sold under the name of digitalis. It is not mentioned in the Michigan 

 Flora as an escape in the state. In 1916, in company with Mr. George W. 

 Howe of Port Huron, Michigan, the writer collected in the territory ad- 

 jacent to the south shore of Lake Superior. Among other places visited 

 was the Peter White Camp, a beautiful place about ten miles from the south 

 shore of Lake Superior, in the western part of Alger County. The purple 

 foxglove was growing wild at this place and also at Howe's Lake, a small 

 body of water near by. Howe's Lake is surrounded by primitive forests 

 and only a short distance from its margin, but entirely hidden from view 

 from the lake, was discovered a small clearing of perhaps a charter of an 

 acre in extent with two very old log hunting huts. The camps and clearing
