for three or more years are similar. For frequency, the terms 

 common, frequent, and occasional have been used. In some cases 

 where it was not well known no statement is made. Unless other- 

 wise stated the plants were considered equally common at both 

 localities. For the convenience of many who may use the list in 

 connection with a manual it has seemed desirable to follow the 

 nomenclature of Britten's Manual, 1 and common names have 

 been included with the idea of making the list useful to as many 

 people as possible. 



The territory covered at Blue Rapids takes as a center the farm 

 on which the writer lived until leaving college. Most of the col- 

 lecting was done on this place or on those immediately adjoining, 

 the greater part within one mile radius, and mostly on the east 

 side of the river. This place is located about four miles northwest 

 of Blue Rapids on the Big Blue River, so that the area studied 

 includes the river bank and woods, the valley, the hillsides and 

 upland prairie. About every half mile deep ravines extend back 

 a mile or more from the valley (or smaller ones more frequently). 

 The wooded lower levels or dry slopes of these are the " dry woods" 

 referred to, while "woods" refers to those close to the river. The 

 natural grassland of the valley is designated as "meadow," that 

 of the upland as "prairie." 



The area at Manhattan forty-five miles south of Blue Rapids 

 was covered quite well to a distance of about four miles in all 

 directions from the town. A greater variety of conditions occur 

 and about 150 more, plants are reported. The hillsides are higher 

 and more moist; good springs are frequent (rare at Blue Rapids). 

 The larger valley of the Kansas River which the Big Blue joins at 

 this point is quite sandy and furnishes some small areas of drifting 

 sand. Eastward from the town the glacial ice sheet left its charac- 

 teristic results which seem to furnish a habitat for a number of 

 plants not found elsewhere in the vicinity. 



vSome prairie plants common at Manahttan which were not 

 seen at Blue Rapids are : Zygadenns Nuttallii, ( 'allirrhoc, and 

 Hymenopappus corymbosus. Many of the other species not recorded 

 for Blue Rapids are likely to be found in its vicinity. Professor 

 A. S. Hitchcock has published- records of about 150 additional
