12 ECONOAIIC BOTANY OF ALABAMA 



LITERATURE CITED. 



The writer's notes on the distribution and utiHzation of our 

 woody plants have been supplemented by examination of all the 

 easily available literature on the subject (Mohr's Plant Life of 

 Alabama first and foremost, of course), and by written and oral 

 communications about a few species by interested persons. All 

 such information is properly credited, and doubtful cases allowed 

 for as far as possible. Reports of additional discoveries will of 

 course always be gratefully received, and utilized if this catalogue 

 should ever be revised. 



The following bibliography includes several different kinds of 

 publications, as follows : 



1. General works, giving the distribution or uses of the 

 woody plants of the southeastern United States, or some larger 

 area. 



2. Works similar in scope to this on other states, which have 

 been taken as models in some respects. 



3. Pamphlets or papers dealing with the classification or util- 

 ization of certain genera or species represented in our list. 



4. Papers dealing specifically with Alabama trees or shrubs. 

 Completeness is not attempted in either of these groups. The 



aim has been to cite only works that are important or easily acces- 

 sible, or both, with an occasional exception in favor of some rare 

 one that has been overlooked by many bibliographers. Those in 

 the first and third classes are mostly government bulletins, partly 

 because the U. S. Forest Service has published more information 

 on the utilization of our trees than any other organization in this 

 country, and partly because government bulletins are printed in 

 large editions, and easily found in libraries if not still available 

 for free distribution. Some papers in the third class, which deal 

 with only one species, are referred to at the proper place in the 

 catalogue instead of being listed in this bibliography. In the last 

 class it has not seemed worth while to repeat all the titles given 

 in Economic Botany Part 1 (Monograph 8), for that is still avail- 

 able for distribution, and even after the reserve stock is exhausted 

 it ought to be found in nearly every library that contains this re- 

 port. In all there are about 139 titles by 80 authors.
