ANNOTATED CATALOGU 



OF 



Grasses Growing Without C 

 Louisiana. 



The following catalogue of Louisiana grasses represents 

 the results of collections made during parts of every summer 

 since 1897, with the exception of two or three quarantine years 

 when collecting was impossible. During this period the writer 

 has visited all the extreme portions of the State, both north, 

 south, east and west, and a very great part of the intervening 

 territory, especially all parts which have any distinctive geo- 

 graphic features such as were likely to be accompanied by cor- 

 responding differences in the flora. There is, of course, the 

 drawback in such a collection that only one season of the year 

 is represented, but with grasses this objection is not so great 

 aL with most other families of plants, as the vast majority 

 bloom and are in their most perfect condition in the late sum- 

 mer and early autumn. Consequently while the writer can 

 hardly hope that this catalogue is exhaustive, it is much nearer 

 so than could be the case with any other large family collected 

 only at one season of the year, and no doubt includes a very 

 large proportion of our wild grasses. 



In view therefore of the special interest taken in grasses 

 by agriculturists and others as shown by the very large number 

 of enquiries received on this subject, and taking into considera- 

 tion the fact that none of the published manuals even approxi- 

 mate accuracy concerning the species which occur in Louisiana, 

 it seems worth while to publish a list which cannot 

 be very far from complete, judging from the number here in- 

 cluded as compared with the number of grasses in other States 

 cf a similar size.
