established. Specimens are at hand which show that it occurs 

 in Guadeloupe, Martinique, and St. Croix, while Grisebach* 

 states that it is naturalized in St. Kitts, Trinidad, and Guiana. 



Langlois in his Catalogue Provisoire de Plantes de la Basse- 

 Louisianef mentions a " Clerodendron sipho" as introduced at 

 Point a la Hache, on the lower Mississippi. This is doubtless 

 the plant that has now become so well established in southern 

 Louisiana. Mr. Wurzlow writes that he has observed it for 

 many years, not only in Terre Bonne Parish, where it is very 

 common, but in other parishes of the southern part of the state. 

 It grows along roadsides, ditch banks, and fencerows, and in 

 cultivated ground to such an extent that it is regarded as a weed, 

 It is distributed by seed, but after the plants are established 

 they spread rapidly by rootstocks, forming large patches. Re- 

 peated cutting or destruction of the tops does not destroy it 

 when it invades cultivated fields. Although frequently seen 

 in neglected places about dwellings it is not known to be in 

 cultivation. 



Prof. R. S. Cocks, of Tulane University, writes that so far 

 as he knows the plant was first collected in 1884 by Dr. Joor near 

 Baton Rouge. He further states that it occurs abundantly in 

 the vicinity of New Orleans and occurs more or less commonly 



throughout southeastern Louisiana, especially in alluvial soils.
