ill the vicinity of Plaquemine, comprising about 1,200 Phanero- 

 gams and 1,000 Cryptogams. This collection was considerably 

 added to by him in succeeding years, and is d^w at the Catholic 

 University of Washington. This is probably the only collection 

 of any size (outside of the writer's) which still exist of the Flora 

 01 Louisiana, and this only professes to cover a small portion of 

 the State. 



The present writer has united into one catalogue the name of 

 every plant that any one of these older botanists has reported, 

 and when reference is made to a plant in the accompanying list 

 as first record from Louisiana, it means that it has not been 

 reported by any of his predecessors, nor credited to Louisiana in 

 any publication so far as he knows. It will be at once evident 

 to any who glances down this list that Cameron Parish must 

 have been overlooked entirely, and when we take further into 

 consideration the fact that most of the results of bygone explora- 

 tions have been lost, it seems that the writer is justified in his 

 statement that Louisiana is to-day almost unknown botanically, 

 whatever it may have been fifty years ago. 



The Gulf Biologic Station is situated at the mouth of the 

 Cameron river, two or three hundred feet from the beach, on one 

 of the series of ridges which run parallel to the sea, traversing 

 the salt marsh by which it is surrounded on every side. This salt 

 marsh runs back for many miles, and with the exception of the 

 succession of ridges which are six to eight feet higher, and which 

 occur at intervals of every two or three hundred yards, the whole 

 country is about at sea level. The region is practically treeless, 

 with the exception of some thickets of Bumdia lanuginosa 

 Xanthoxylon Clava-Her cutis, and a few stunted specimens of 

 Hackberry on the ridges. These show in a marked degree the 

 effect of the breezes from the Gulf, as many of them have the 

 upper portion growing almost at right angles to the lower, in a 

 direction away from the sea. A certain amount of the marsh is 

 cultivated, and the soil is said to be extremely fertile, producing 

 without fertilization one, or even two bales of cotton to the acre. 



Speaking roughly, the vegetation in the neighborhood of the 

 station may be divided into five groups. First are the true halo- 

 phytic salt water loving plants growing in the wet sands. Of this
