A. H. Curtiss, no. 1195* (type, in Gray Herb.) ; Key West, Blodgett; 
Jew Fish Key, Chapman; rich thicket, Key Largo, June, 1880, A. H. 
Curtiss, no. 171; Upper Metacumbe, 11 April, 1892, J. H. Simpson, no. 
565. This species, long identified with the Jamaican LE. heteroclinium 
Griseb., differs in having decidedly smaller heads, shorter leaves of a 
more deltoid contour, more obtuse involucral scales, olivaceous instead 
of dark violet-brown achenes which are strigillose instead of smooth on 
their faces, and in other minor characters. Were these plants of 
Florida and Jamaica really identical, it would certainly be strange that 
their range did not include Cuba. 
Evupatorium GLaABRatum HBK. Nov. Gen. et Spec. iv. 127 (1820). 
‘To the synonymy of this species should be added EF. zalapense HBK. |. . 
128 (1820), and #. gonocladum DC. Prod. v. 171 (1836). The greater 
part of recently collected material of this affinity has been referred to Z. 
glabratum, while E. xalapense and EH. gonocladum have remained ob- 
secure. After examining at the herbarium of the Museum of Natural 
History in Paris original material of E. glabratum and EL. xalapense, 
and at the De Candollean herbarium in Geneva the exceedingly frag- 
mentary type of #. gonocladum, the writer has failed to detect any sig- 
nificant difference. Of the two earlier names, the more commonly used 
£. glabratum happily has priority of position.
