PLANTS OF ARKANSAS. 157 



Professor Blatchley. — Professor Willis S. Blatchley, of 

 Terre Haute, Indiana, an experienced botanist and observer, 

 was engaged by the Geological Survey for some months in In- 

 dependence county, and in studying the borders of the high- 

 lands from the Missouri line just west of the St. Louis, Iron 

 Mountain and Southern Railway to near Beebe. During that 

 time and in the region mentioned he made a number of val- 

 vable additions to the list, and in other cases confirmed obser- 

 vations made by others. 



Professor McNeill. — Professor Jerome McNeill of the State 

 University at Fayetteville, has also made some additions to the 

 list from the flora of Washington county. 



Mr. D'Ailly.— Mr. Richard D'Ailly of Little Rock has for 

 many years given more or less attention to the botany of the 

 state. He has kindly given us the benefit of his knowledge 

 in preparing the list. The species reported by him are in his 

 private herbarium in this city. 



Authorities — There is some difficulty in giving authorities 

 for reporting the plants mentioned in the list. The more com- 

 mon ones have been observed and recorded by so many of 

 those who have co-operated with us in preparing the list that 

 it has become impracticable to mention all the names in con- 

 nection with each species. When a plant has been reported 

 by three separate observers therefore the names of the authori- 

 ties have been omitted altogether. No doubt this omits a certain 

 class of desirable information from the list, but there are urgent 

 reasons for encumbering it as little as possible. 



Value of the plant list. — This list makes no pretension to 

 being anything more than a bare list. It gives nothing or next 

 to nothing about geographic distribution, and does not even 

 pretend to say whether the plants mentioned are rare, com- 

 mon or abundant. But aside from its scientific interest, even 

 such a bald list of the native plants of the state has important 

 economic value.
