Keating,* both by its common and botanical names. Here are 

 five states, besides some of British America, lying outside of the 

 lake region wholly or in great part, where Zizania is found, gen- 

 erally in abundance, Indiana, Illinois, Iowa, Wisconsin and 

 Minnesota. And this region is the one mentioned at the begin- 

 ning of the paragraph. 



I will now mention a few plants whose range as indicated 

 In the Manual, is either too restricted or otherwise incorrect, as 

 they have fallen under my notice, indicating also where Informa- 

 tion may be found concerning them. 



Corydalis micrantha, Gray, should be credited to Illinois, 

 "Sandy river banks, &c., throughout the State " (Patterson; Cat. 

 of the Plants of 111., 1876). 



Lechea thymifolia, Michx. Abundant in the sand-barrens at 

 the head of Lake Michigan in Ind. (Bot. Gaz., 1S81 as L. Nov(B- 

 C(SsarecB, Austin, and in 1883 as L. thyviifolia, Michx). 



Arenaria patula, Michx, Tippecanoe Co., Ind. (Cat. of the 

 plants of Ind. by the Editors of the Bot. Gaz., 1881). Near Chi- 

 cago, 111., (Babcock; Flora of Chicago and vicinity. The Lens, 

 1872). I know of no place in Illinois where it is found except 

 here. One of these stations is west of the city at Riverside on 

 the Desplaincs River, and two on the south side, within the limits 

 of the city, where it grows in the thin soil coverln^^ limestone 

 rocks. As they are hkcly soon to be extinct by r 

 growth of population, they may be placed on record; one Is 75th 

 St., near the lake, and the other "Stony Island," near 93d St. 

 This is an interesting example of a plant, southern In genera! 

 range, that comes to the head of Lake Michigan, where some plants 

 of a sub-alpine cast are also found. The station in Tippecanoe Co. 

 may Indicate the hne of connection. 



Stcllaria crassifolia, Ehrh. Michigan. (Wheeler and Smith's 

 Cat. of the Plants of Mich., 1881), given on the authority of Dr. 

 Lyon, and without locality. For Illinois, besides the station men- 

 tioned in the Manual (Ringwood) may be given Crete, Will Co., 



near the Indiana State line, where I found the apetalous form of 

 the plant In 1882.
