Notes. 



85. I have called this a form of Juniperus communis, L., which grows on the 

 narrow divide between Bar lake and Lake Michigan. The shrub bends over on 

 the ground equally in every direction in the way characteristic of J. communis 

 alpina. Gaud, as I saw it at Arlington Heights, Mass. The leaves are closely 

 appressed to the stem, but I could not see that they are much shorter than in the 

 type. 



126. This is a form of Panicum nitidum, Michx. (-P. spfprocarpon. Ell.) pilose 

 with long white spreading hairs. It agrees with New England specimens marked 

 "var. pilosum" in the herbarium of the Harvard botanical laboratory (no name 

 given as authority for the variety). It is apparently distinct from P. pubescens, 

 Lam. 



176. A form of this golden rod occurs along the M. & N. E. tracks with entire 

 leaves and ample panicle. The panicle resembles that of S. serotina, Ait., but Is 

 glabrous as in S. juncea. Ait. It resembles closely a specimen of S. Missouriensis, 

 Nutt., from New Mexico, which is in my herbarium. Perhaps it is a hybrid between 

 S. juncea, Ait. and S. serotina. Ait. 



236. This 1 found in the herbariums of several high school students at Manistee. 

 Several said that they gathered it in the woods back of Oak Grove cemetery, but 

 a diligent search failed to find it there or anywhere in the vicinity of Manistee. 

 Perhaps it was exterminated the year before by the students. In Lake county, 

 near Filer's Camp, I found a single specimen. 



398. The sedge I have so named grows to a height of about two feet, the culm is 

 wing margined, presses perfectly flat; the leaves are three to four lines broad, some- 

 what shorter than the culm; head two inches long, somewhat interrupted, bearing 

 a few setaceous bracts; perigynium slenderly ovate, long-beaked, the beak toothed 

 and rough; scale cuspidate, a little shorter than the perigynium, the rib dark 

 green, the margins greenish white. The leaves are much too broad for C. tere- 

 tiuscula, Gooden. The culm is too sharply angled for C. decomposita, Muhl. The 

 beak is not long enough for either C. stipata, Muhl. or C. crus-corvi. Shut. Possibly 

 it is C. alopecoidea, Tuckerm., but the inner face of the perigynium is three nerved; 

 it is thickened at the base, not obviously stipitate. It is also larger than in C. vul- 

 pinoidea, Michx., which does not at all resemble our plant. 



590. This plant has large oval opposite floating leaves (2i/!> in. x 5 in.); petiole 

 short; stipules bicarinate 2-2^/^ in. long; peduncle thickened upwards, over 4 in. 

 long; nut roundish, tri-keeled, middle keel large. It is near P. amplifolius, 

 Tuckerm. 



632. This plant, too young for accurate determination, has sagittate-clasping 

 undivided leaves and white flowers.
