TWO PLANTS NEW TO THE FLORA OF LOUISIANA 



By Paul C. Standley* 



Only a few months ago the writer published an accountf of 

 the occurrence in southern Louisiana of a species of Siphonanthus, 

 more commonly referred to Clerodendron. The specimens upon 

 which the report was based were sent from Houma by Mr. E. C. 

 Wurzlow. The same collector has forwarded to the U. S. 

 National Herbarium, from the same region, specimens of a true 

 Clerodendron, granting that this is a genus distinct from Siphon- 

 anthus.

This species is not new to the United States, for in the second 

 edition of Small's Flora of the Southeastern United States it is 

 included in the appendix, its range being given as "in fields and 

 thickets, Florida." Mr. Wurzlow states that it has become 

 thoroughly naturalized in the alluvial portion of southeastern 

 Louisiana, where it grows in waste land, in and about cultivated 

 fields, frequently along fencerows. It is a perennial, 2 to 6 feet 

 high, forming large clumps. The showy lilac purple flowers are 

 borne in dense terminal corymbs 4 to 8 inches broad. The 

 foliage possesses a very unpleasant odor, and on this account, as 

 well as because of Its tendency to spread, the plant is destroyed 

 when it appears about dwellings. 



The species was described from northern China and occurs 

 also In Japan. It is sometimes cultivated as an ornamental 

 plant in the southern United States and Is said to be hardy as 

 far north as Philadelphia.

Carolina and Florida to Alabama. Living specimens have been
