grew in Minnesota, since it was found on both sides of that State, 

 in Canada and Illinois. But the only place for it yet found in our 

 limits, so far as I am aware, is the station originally given. When 

 in Minnesota the past season, I had hoped to see it, but the north- 

 eastern part of the State is not suitable for its propagation. It 

 is a plant of the prairie and plains, and would hardly come by the 

 timbered region of the lakes to a southern locality, or be repre- 

 sented in its flora. If anywhere to be sought, it would rather be 

 in the open country of the Mississippi Valley, where the streams 

 would afford a still better means of communication.

 The Manual gives this range, which is well enough for extent but 

 not accurate as to conditions. The plant is not confined to those 

 which are saline, but is found in many places along the lakes and 



Valley, where they do not exist. The older

Rosa Engehnanni, Watson. This was found last season in 

 the sand barrens at the head of Lake Michigan, and is not uncom- 

 mon. It had been to me a puzzling form of R. blanda^ Ait., 

 placed there for want of something better, till the description and 

 figure in Garden and Forest of Aug. 7, 1889, ^vere seen. Being at 

 Tower, Minn., at the time, it was at once seen to be the more 

 common form of Rose there, and on returning home in Septem- 

 ber, a comparison of fruit and foliage verified its presence here. 

 The fruit of the Minnesota specimens was usually obovate-oblong, 

 that of the Indiana oblong, or tapering about the same above as 

 below, showing no punctures by insects to produce deformity, 

 and moreover characterizing the fruit of a whole bush, it seemed 

 a well-marked species. An occasional round or roundish fruit 

 would api^ear on some bush, as though showing a tendency to 

 mix with R. blanda and /v. humilis, that grow plentifully in the 

 immediate vicinity. 



Utrietdaria purpurea^ Walt. Found in Spring Lake, Mich., 

 where I gathered it in 1872. 



Sagina procnvihois, L.. Champion Mine, Mich., 18S9. 



Potamogeton Robbinsii, Oakes. Republic, and Negaunee 

 (in Goose Lake) Mich., and abundant in Chesago Lake, in eastern 

 Minn., 1889. 



P.obtusifolms, Alert, and Koch. Tower, Minn., 1889.
