In Louisiana the writer has always found it in the driest situa- 

 tions possible. 



The writer was collecting too early in the season for the 

 majority of Compositae, and many, even of those that were col- 

 lected, were too immature for positive identification, so that the 

 following notes refer only to a few particularly interesting 

 species. 



Solidago. 

 The following species of Solidago were in bloom early in 

 September, when the writer was collecting: 



Solidago sempervirens. 



Solidago stricta. 



Solidago radula. 



Solidago, three species, undetermined. 

 All these three species are known from many localities in 

 the State.. Solidago sempervirens is particularly common in the 

 vicinity of New Orleans in empty and unfilled lots. It is perhaps, 

 worth noting that the writer has collected it blooming in every 

 month of the year. Almost every year it can be found blooming 

 from the middle of March to December. 



Gaillardia Species. 

 One species of Gaillardia was abundant in the prairies, es- 

 pecially on the somewhat more elevated ridges, and was sent by 

 the writer to Dr. E. L. Greene. Of this plant, Dr. Greene wrote: 

 "I have no doubt it is a good new species of Gaillardia, and I 

 would name it Gaillardia gauroides, it is so like some Guar as I 

 know in growth and foliage." 



Rudbeckia. 

 The following species of Rudbeckia were collected on the 

 prairies : 



Rudbeckia fulgida Ait. 

 Rudbeckia grandiflora C. C. Gmelin. 

 Rudbeckia maxima Nutt. 

 Rudbeckia nitida Nutt. 



Rudbeckia Floridana J. V. Moore var. angustifolia. 

 Rubeckia alismae folia T. G. 

 Rudbeckia glabra D. C. 

 All of these species, with the exception of Floridana var.
