PREFACE 



This bulletin is to be one of a series which the Board of 

 Curators of the Louisiana State Museum propose to have pub- 

 lished on different families of plants in Louisiana, with the 

 view of publishing eventually a complete State Flora. They 

 believe that such a work will be of great value, because not 

 only has very little botanical literature dealing directly with 

 Louisiana been published for the past fifty years, but also 

 the State is very meagrely represented in the large herbaria 

 of the country, and, as a consequence, the distribution and oc- 

 currence of plants in this State is very inadequately treated 

 in all the standard manuals. 



The appended catalogue is based, with a few exceptions, 

 upon the writer's own collections made at scattered intervals 

 during the past twelve years, this collection being now at 

 Tulane University. The exceptions are : 



First. A few plants collected between 1840 and 1860 by 

 the pioneer collectors in Louisiana, Riddell, Hale and Carpen- 

 ter. They collected at the same time, but in different parts 

 of the State ; Riddell, mostly in the vicinity of New Orleans 

 and Southwest Louisiana ; Hale, mostly in the neighborhood of 

 Alexandria and Northern Louisiana; Carpenter, in East and 

 West Feliciana, the eastern portions of the State. These plants 

 are also at Tulane University, but in the absence of definite 

 locality labels the writer has been unable to ascertain whether 

 these species still occur where they were originally collected. 



Second. Two or three plants have been included upon the 

 authority of a catalogue of plants of Louisiana published in 

 France, in 1887, by the Rev. A. B. Langlois, entitled "Cata- 

 logue Provisoire de plantes phanerogames et cryptogames de 

 la Basse, Louisiane." The collection upon which this cata- 

 logue is based is at the Catholic University, Washington. 



Thirdly. A few plants have been included upon the 

 authority of Small's Flora of the Southern States. These 

 plants are presumably in the herbarium at Bronx Park. In
