served by local botanists as had the central and southern parts, where 

 men like Brendel, Hall, Meade and Wolf had worked. The names of 

 some contributors are mentioned by Dr. Vasey; that of Dr. F. Scam- 

 mon, of Chicago, being one, and we probably owe to him or to Dr. 

 Vasey the reporting of the plant from Illinois. The list does not 

 specify localities, but it might be looked for in the sandy or dune-lined 

 shores of the lake, wherever such conditions prevail, from Waukegan 

 to the Indiana line, mainly from Evanston south. It could not have 

 been far from this date that our plant became known west of Lake 

 Michigan. The first recorded notice of its presence here, is in " The 

 American Entomologist and Florist^" of which Dr. Vasey was botanical 

 editor. Writing of plants collected near Chicago, Mr. H. A. Warne 

 says, in the number for October, 1870: " Kalm's St. John's-Wort 

 abounds immediately in the vicinity of the lake ; its large, yellow 

 flowers, in the greatest profusion, gleam like gold." I need only add 

 to these two citations that the plant is given in Babcock's *' Flora of 

 Chicago and Vicinity," published in The Lens (1872); in Patter- 

 son's "Catalogue of the Plants of Illinois" (1876); and in a similar 

 list of those of Indiana by the editors of the '■'• Botanical Gazette" 

 (1881), and several times since. 



For the State of Wisconsin it is not listed in Dr. Lapham's "Plants 

 of Wisconsin " in the first volume of the Proceedings of the American 

 Association for the Advancement of Science (1849), o^^ of the earliest 

 papers offered to that body. Localities are mentioned in but few 

 cases, for the plants were principally collected by Dr. Lapham him- 

 self, " within thirty miles of the city of Milwaukee, unless other lo- 

 calities are mentioned." It is interesting to note in this connection 

 that of the "four hundred and sixteen genera, and eight hun- 

 dred and forty -nine species" — almost exactly two to a genus 

 on an average, embraced in the list, but two Hypericums find 

 a place, Hypericum Canadense from Lake Superior, on the au- 

 thority of Dr. Douglas Houghton, and H. pyramidatuvi., from 

 Waukesha, contributed by another party. Dr. Lapham had only 

 met with Elodes Virginica of this family, within that semicir- 

 cle about Milwaukee, with a thirty-mile radius. Hypericum Kal- 

 mianum had however become known in Wisconsin before 1882, for it 

 is given in a list of the plants of the State, by G. D. Swezey, published 

 in the first volume of the "Geology of Wisconsin," with the above 

 date. No locality is specified. The number of recognized Hyper- 

 icums had in the meantime increased to ten. 



The finding of Kalm's St. John's-Wort in the valley of the St. 

 Croix river is in keeping with what might be expected regarding its 

 distribution. The farthest west I have met with it in Michigan was
