logue that this is the meaning when locahties are not specified, 

 that of the lower Wabash being for height of stem (19 feet) and 

 not for locaHty. Dr. A. J. Phinney, in a hst of plants of central 

 eastern Indiana, published in the Twelfth Report of the State 

 Geologist, (1882) says it is common in the region embraced in 

 his list, about four counties lying in the valley of the Ohio. Pat- 

 terson, in his " Catalogue of the Plants of Illinois," states that it 

 is "common "in the State without restriction of range. It is 

 given by Dr. Lapham in his " Native, Naturalized, and Culti- 

 vated Grasses of Illinois," (1850). In Minnesota, on the author- 

 ity of Upham, we find it " common or frequent in the edges of 

 ponds and lakes throughout the prairie portion of the State." It 

 is given by Arthur in the list of Iowa plants, and by Lapham in 

 that of Wisconsin. Hence we find the upper Mississippi region 

 well represented by Phragmitcs communis. 



The third plant is Zizania aquaiica, L. " Common " says 

 the Manual. "Along the seaboard and the Great Lakes, but

where else," Prof. Porter asks. The answer is the upper 

 ippi and the Red River of the North, as can be easily shown. In 

 fact, if we take account of its use by the Indians as a consequence 

 of its abundance, it is a plant even more characteristic of these 

 regions than of the seaboard and Great Lakes. It is published 

 in all the lists cited for Phragmitcs communis, and with about the 

 same range, though less common at the south. In Indiana, out- 

 side of the lake area, it is assigned a place in Gibson County, and 

 in the four counties of Dr. Phinney's list. In Illinois, Patterson 

 has it "common." In Minnesota, Upham says, "common or 

 frequent in favorable situations throughout the State." Besides 

 these may be mentioned Dr. Parry's " Synoptical Catalogue of 

 the Plants of Wisconsin and Minnesota," published in Owen's 

 Report, (Philadelphia, 1852) and Dr. Douglas Houghton, in a 

 . list appended to Schoolcraft's " Narrative of an Expedition 

 through the upper Mississippi to Itasca Lake." He closes the 

 list with the entry, "-Zizania aguatica, Pursh. Illinois to the 

 sources of the Mississippi." I do not find it in the short Hst pre- 

 pared by De Schweinitz from plants collected by Say in connec- 

 tion with Long's Expedition to this region, but it is frequently 

 mentioned in the account of the expedition compiled by Prof,
