same thing has been done many times in other instances in 

 both botany and zoology, and has been held as filling the 

 requirements. The species was described from Colombia. 



This plant has been collected a number of times since its 

 description, and always labeled in our herbaria, " Elephant- 

 opus spicatus" with which it has scarcely anything in com- 

 mon excepting the spicate arrangement of the glomeruli. 

 Indeed in the Bernhardi herbarium is a single sheet bearing 

 a slip of Spirochaeta and another of Pseudelephantopus side 

 by side under the same label. These specimens probably 

 came from somewhere along the northeast coast of South 

 America. Eusby's No. 1109 and Bang's No. 357, both from 

 Bolivia, belong to this genus and apparently to this species, 

 8. Funckii, though both were distributed as E. spicatus, 

 without question or remark. 



The freely rooting runners at base of stem are quite pecu- 

 liar to this form, while the pappus clearly distinguishes it. 

 This latter is in one series with the paleae minute and lacer- 

 ate and the setae spirally twisted toward their tips. These 

 setae are very brittle and easily broken off, so that an at- 

 tempt to remove them entire should be made with care. 



Genus Elephantosis Lessing, Linnaea. 4 : 322. 1829. 



This genus, distinct by its pappus of numerous straight 

 setae in two series, contains the common and variable West 

 Indian B. angustif olius (WiWd.) Less., and also several other 

 species, but one of which, quadrijioy^a Less., has ever been 

 described. The latter was originally described from Brazil. 

 Neither Bang's No. 344 from Bolivia nor Morong's No. 313, 

 from Paraguay, appears to be angustif olius, though both were 

 distributed as such. Far more material will be necessary 

 to any satisfactory arrangement of the species. Lessing 

 regarded the nudiflorus of Willdenow from Jamaica and San 

 Domingo as distinct from angustif olius.

All of the forms of this genus examined, present the same 

 peculiar structure of pappus which marks them as widely dis-
