FLOWERING PLANTS A.ND FERNS OF [NDIANA. 595 



Blatchley has also added very many forma to the flora of the State as 

 the result of his energetic field work and critical studies. 



Dr. Robert Hessler has always furnished answers to my numerous 

 inquiries, and has. in many ways, aided in the preparation of this 

 report. 



Dr. J. T. Scovell, of Terre Haute, has also placed the results of his 

 investigations at my disposal, and my only regret is that I have been 

 unable to avail myself of his assistance to the fullest degree. Some of 

 his recent studies upon the flora of Lake Maxinkuckee and its sur- 

 roundings I have been wholly unable to use. They would have added 

 much to the value of the report, but will perhaps have a greater value 

 published as a separate study of a special region. 



To Mr. 0. M. Meyncke, of Brookville; Mr. G-. W. Wilson, to Hon. 

 Francis Walker, of Anderson; Mr. J. N. Jenkins, of North Man- 

 chester; Eev. E. J. Hill, of Englewood, 111.; Dr. J. Schneck, of Mount 

 Carmel, 111.; the late Elwood Pleas, Esq., together with a large num- 

 ber of other correspondents, I am under large obligations. 



I wish also to acknowledge the valuable assistance of Dr. D. T. 

 MacDougal, furnished by him during his connection with the instruc- 

 tional corps of Purdue University, assistance both in the collection of 

 material and in critical studies. 



To Miss Alida M. Cunningham, a graduate of Purdue University, I 

 am greatly indebted for a series of critical studies covering a period of 

 three years, for a large collection of plants and for much assistance in 

 cataloguing and in the summation of data. Without her work it would 

 have been impossible to have presented the catalogue at this time. 



To Mr. Herman Dorner and R. S. Twells, of the senior class at Pur- 

 due, I am indebted for valuable assistance, especially in the study of 

 synonymy and distribution. They have rendered a cheerful and intelli- 

 gent aid, which has greatly lightened the labor involved in the prepa- 

 ration of the catalogue in its present form. To Messrs. Victor Thomp- 

 son, Guy E. Sutton and F. E. Trucksess, senior students in botany at 

 Purdue, I also make acknowledgments for kindly assistance rendered 

 upon every possible occasion. 



To the many others who have responded to my communications for 

 special information, I make this general acknowledgment, their special 

 services being credited in the body of the report. 



In conclusion, I wish to express my appreciation of the aid given 

 by the botanists of the country, who have given freely of their services 

 in the determination of doubtful forms, an aid which gives an added 

 value to the list as published.
