feet or more, with flowers large and well formed, the evidence was 

 conclusive that it easily bears cultivation. I learned that the stock 

 from which this was brought was also cultivated. 



Hippuris vulgaris, L. Grows in a small stream at Otis, Ind., 

 ten miles west of Laporte. It is the only place where I have seen 

 this plant, comparatively rare, in this vicinity. I do not often meet 

 with it elsewhere, the only time, as I have it recorded, in Bear River, near 

 Petoskey, Mich., and at Frankfort, Mich., both stations on the eastern 

 shore of Lake Michigan. 



Cornus Canadensis, L. As in the case of some other species of 

 Cornus, this was found both in flower and fruit at Manistee, Mich., 

 August 6, 1880. 



Erigeron beiUdifolium, Muhl. Specimens with white flowers were 

 found last year at Whiting, Ind. Also those witn pale pink rays vary- 

 ing to white. Nearly all the flowers seen the present season are white. 



Diplopappiis umhchatus, Torr. & Gr. Plants roughish and 

 pubescent occur at Whiting. Similar forms were found this year at 

 Sault Ste. Marie. Those thickly covered with hair were obtained at 

 Bruce Mine, on the St. Mary River, Ontario. 



Bidehs Beckii, Torr. This plant, credited in Gray's Manual 

 (and on the same authority in Patterson's Catalogue of Illinois Plants) 

 to Illinois, but without locality, grows in the Calumet River at South 

 Chicago. Occurs also at Manistee, Mich. 



Cniciis Fikhen, Torr. Grows on the sandy shore of Lake 

 Michigan, at Pine Station, Ind. Also found in similar places at Pe- 

 toskey, Mich. In both places it is associated with Solidago Vi'rga- 

 aurca., L. , var. humilis, Gray. 



Veronica Anagallis, L. Plants glandular hairy (Gray's Syn. Fl. 

 N. A.) are found at South Chicago. 



Sparganiiim niinivium, Bauhin. In ponds at Manistee and in 

 "sloughs" at. Pine Station. These are the only localities where I have 

 seen this plant during many years of collecting, and it is not abundant 

 in either place. 



Potamogdon Claytoni, Tuck. In creeks of Pere Marquette River, 

 Ludington, Mich., forms occur with floating leaves i^^ '-31^' long, 

 and the submersed leaves 7- nerved. 



Potamogeton pcrfoliatus, L. I find typical forms of this in the Lit- 

 tle Manistee River, at Manistee, with short, roundish or oval leaves. 

 Nearly all the plants gathered at the Wesfhave the lanceolate leaf, 

 usually shorter than in the type specimen (var. lanceolatus, Robbins.). 

 They gradually vary with all degrees of difference between the variety 

 and the typical species, so that it is often hard to tell to which they 

 should be assigned. 



Potamogdon Niagarensis} Robbins. This plant, probably only 

 a variety of P. pauciflorus, Pursh, has been found common in several 

 places near here the past season. I have traced it as far east as Otis, Ind.
