OBSERVATIONS ON THE NATIVE PLANTS OF OKLAHOMA 

 TERRITORY AND ADJACENT DISTRICTS. 



By M. A. Cakleto.v, ass'tnlaiit hoianist, Kansas Agrietiltural Experiment Siat'um. 



In order to make out aiiytliiiij;' like a complete statement of tlie dis- 

 tribution and variations of the native plants of the above-nanuHl 

 country, it would, of course, be necessary to survey systematically the 

 entire territory included, visiting each district at all seasons of the 

 year and taking two or three years of time for tlie pur]>os(% The fol- 

 lowing notes arc taken from a sojourn of less than six natnths in tln^ 

 regions mentioned during the summer (tf 1801, although several of the 

 districts were visited two or three times during the summer. However, 

 1 have taken pains to invtistigate all distributions and variations of 

 plants that seemed to be in any way signiticant, and it is hoped the 

 following summary of results may prove interesting. 



I shall first give some notes on the plants of the different districts of 

 this region, and then direct attention to certain groups. 



The entire region over which 1 have worked is a]>proxiinately inclinled 

 between the Ai'kansas and Canadian rivers, west of Arkansas and east. 

 of Colorado and New Mexico, but some of my notes will refer to the 

 northeast portion of the Indian Territoiy and of Kew Mexico and the 

 southeast x><'i'tion of Colorado. For convenience I divide the whole 

 region into five parts: (1) Oklahoma ])roper and eastern Indian Terri- 

 tory (or the Indian Territory east of the flSth meridian); (2) western 

 Indian Territory (west of the !)8th meridian), excdnding No Man's Jjan<l ; 

 (3) southwest Kansas (that part of Kansas cut off by the Arkansas 

 liiver); (4) No Man's Land or Neutral Strip; and (5) Texas ranhandle 

 north of the Canadian Kiver. 



OKLAHOMA PROPEU AND EASTERN INDIAN TERRITORY. 



The greater part of this distri(!t I have visited but once, and then 



early in the spring, and therefore can not say much about its flora from 



my own knowledge. But I believe I have made sufficient observations 



to justify me in expressing the opinion that it is a country in the main
