Baker — A Revision of the Elephantopeae. — I. 53 



The species, most of which are little known, or as to our 

 herbaria, entirely unknown, may be listed as follows: — 



1. elongatus Hook. — Brazil. 



2. hirtijiorus DC. — Brazil. 



3. Martii GxKh. — Brazil. 



4. mollis HBK. — Widely distributed. 



5. palustris Gardn. — Brazil. 



6. paniculatus Mart. — Brazil. 



7. racemosus Gardn. — Brazil. 



8. Biedelii Sch. Bip. — Brazil. 



9. riparius Gardn. — Brazil. 



10. scdber L. — Isthmus of Panama? 



11. vaginatus Gardn. — Brazil. 



12. virgatus Desv. — Guiana. 



On the Isthmus of Panama also occur forms which are ap- 

 parently undescribed, as for instance, Fendler'sNo. 163, as 

 well as many others from other regions. 



SPECIES OF AFRICA. 



Only two species appear to be reported from Africa ; scaher 

 L. and senegalensis (Klatt. ) O. & H., both representing dis- 

 tinct and well-marked forms. Herbarium material, however, 

 indicates the existence of several other species in Africa. 



SPECIES OF THE FAR EAST. 



Here we find the original home of scaber. Besides India, 

 it apparently occurs in Ceylon, Formosa, and many of the 

 Malasian and Australasian islands. In the Flora Filip., 

 Blanco describes serratus and dubius. We are likely to know 

 more of these soon. Two species have also been described 

 from Java — sinuatus Zoll. & Mor. and ciliatus Zoll. & Mor. 



Genus Spirochaeta Turczaninow, Bull. Soc. Nat. Mosc. 

 241 : 166. 1851. 



This clearly separable genus, well described and founded 

 on remarkably good characters, unique in the tribe, has either 

 been wholly neglected or thrown in with Elephantopus, appa- 

 rently because the single species did not have in the original 

 description a separate characterization. But this cannot be 

 held as a vital deficiency, when incorporated with the generic 

 definition is a perfectly clear diagnosis of the species. This
