93 Britton Shafer (op. cit., 552) extend this range to Missouri, presumably the southwestern part. 

 G. F. Bush, in a letter dated Jan 4, 1899, informed the writer that he had found this tree in Barry County, 

 Mo. 



M Erythrina herbacea arborea Chapman, Coralbean, occurring in southern Florida (coast region from 

 Miami, Dade County, to the southern shores of Tampa Bay) and on the southern Keys, from 10 to 20 feet 

 high, possibly should be added to our tree flora. There is, however, doubt as to whether it is to be consid- 

 ered a strictly woody plant, because, except in the tree-like form of its stem, it has no other characteristics- 

 distinguishing it from the herbaceous Erythrina herbacea Linnaeus, which ranges in the Coast Region from 1 

 North Carolina to Texas. It may be that under especially favorable conditions for growth, this species- 

 assumes tree form, which is the only distinguishing characteristic of the variety, and this might be con- 

 sidered an insufficient basis for creating a distinct variety. By some, authors it is treated as a species,, 

 Erythrina arborea (Chapman) Small.
