 a liordfrland region l)et\veen tlit- (Tnfy's Manual and AVestern Texas Manual n- 

 gions. L'ntil about five years ago the plants of this district were but little known 

 to botanists, and tlie results of recent collections disclose a flora rich in interest- 

 ing forms. Especially valuable is a ''List of Plants Collected by C. S. .Sbeldon 

 and M. A. Carleton in the Indian Territory in 1S91," published as contribntions 

 from the National Herbarium in 18!*2. 



The months of July and August, 181*3, were spent in and about Payne ( 'ouniy. 

 in the very northeast of Oklahoma, about ninety miles so\ith of the Kansas line 

 through the Cherokee strip arid about loO miles west of Arkansas This is in 

 latitude abovit 97° west, and is but a few miles south of the parallel Imumling <»n 

 the north Tennessee and North Carolina, so that the collections were made just 

 south of the line of the extreine southwestern limit of (Tray's Man'., (>th cd. 

 About 175 species of Phanerogaiiis'and Pteridophytes were collected, about sixty 

 of them being new to'Messrs. Sheldon and Carleton's lists, most of thesej however, 

 the commoner plants'; and thirteen of which are not reported in Gray's ^fanual. 

 Of this thirteen four are not included in Dr. Coulter's Manual of the Texas Flora, 

 nor nine of them in his Botany of the Rocky Mountain Region ; l)ut only oiw of 

 the thirteen "fails to be reported in all of these manuals of the surroiiuding re- 

 gions. This is Oenothera trifida, L., determined by Prof. John M. Coulter and 

 pronounced by him "})robably r<(/-. iutegrifolu't, Tdrr. and Gr.. although the s])ecies 

 and variety show various stages of intergradation." Tiiis )dant was somewhat 

 abundant in cultivated fields near Cimarron City. 



These thirteen plants are 'Talirmni r-alyclnum, Engelm., found abundantly on 

 the red sandstone rocks outcropping in ravines and along the Cimarron River::
