tional value by Endlicher in 1836. It is the typical section 

 of the old genus and synonymous with JSlephaniopus Linnaeus 

 (sens, strict.). In 1847, Schultz Bipontinus separated the 

 section Micropappus for the very interesting species of the 

 same name. 



These generic and sectional names have met with varying 

 treatment at the hands of botanical writers. In 1817 Cassini 

 recognized Elephantopus and Distreptus. In 1829 Lessing re- 

 duced PseudelepJiantopus to the later Distreptus and described 

 Elephantosis . In 1836 De Candolle recognized ElephantopuSy 

 Elephantosis and Distreptus. In the same year Endlicher 

 used Euelephantopus, Elephantosis and Pseudelephantopus as 

 sections of the old genus, reducing Distreptus and Matainoria 

 to synonyms of Pseudelephantopus. In 1830, Sprengel men- 

 tions Matamoria as a synonym of Elephantopus. In 1843 

 Walpers practically followed Endlicher. In 1847 Dietrich 

 places all the species under Elephantopus, mentioning Ele- 

 phantopsis and Distreptus as synonyms. In the same year 

 Schultz Bipontinus rearranged the species, using the follow- 

 ing names for sections of the old genus Elephantopus: 

 Euelephantopus, Micropappus, Elephantosis, Elephantopsis, 

 and Pseudelephantopus ( = Distreptus). In 1873 Bentham 

 and Hooker discussed Matamoria as a synonym of Elephan- 

 topus, Elephantosis as of sectional value, and Spirochaeta 

 with Pseudelephantopus as equivalent to Distreptus, which is 

 given sectional value. Finally, in the Index Kewensis, and 

 in Engler and Prantl, all of these names are thrown together 

 without remark under Elephantopus. 



The groups given generic value in this paper, with their 

 types and type localities, are as follows : — 



1. Elephantopus L. — scaber L. — East Indies. 



2. Spirochaeta Turcz. — Funckii Tnrcz. — Venezuela. 



3. Elephantosis Less. — angustifolius Sw. — Jamaica. 



4. Pseudelephantopus Rohr. — spicatusSvf. — Guiana. 



5. Elephantopsis Sch. Bip. — biflora Less. — Brazil. 



6. Micropappus (Sch. Bip.) — micropappus Less. — Brazil.
