NO. I COLLECTIONS OF LOBB IN COLOMBIA KILLIP I3 



COMPOSITAE 



EuPATORiUM DiPLODiCTYON Robinson 



" Lobb, Columbia " written on sheet. 



This is the type of the species, and has never since been discovered 

 in Colombia, though J. F. Macbride recently collected the plant near 

 Muiia, in central Peru (no. 4296). Doctor Robinson has briefly dis- 

 cussed '' these dubious " Colombia " collections of Lobb's. 



CONCLUSIONS 



The material here presented covers doubtless only a small fraction 

 of the Lobb Colombian specimens cited in literature and a smaller 

 fraction of those in the Kew herbarium, but the following conclusions 

 apparently may safely be drawn : 



1. That Lobb made a collection, probably a small one, in the pres- 

 ent Department of Nariiio, in southwestern Colombia, and that these 

 specimens represented characteristic species of that region. 



2. That he collected a few plants at a northern port of Colombia 

 probably Cartagena or Santa Marta. 



3. That he made large collections in southern Ecuador and smaller 

 collections in central and northern Ecuador, and that a great majority 

 of these sheets are labeled erroneously " Columbia," a few, perhaps, 

 " Peru." 



4. That he collected extensively in the mountains of central Peru, 

 many of these sheets being labeled " Columbia." 



5. That botanists should view with suspicion all " Lobb, Columbia " 

 citations in literature or inscriptions on herbarium sheets, and should 

 hesitate before ascribing any extraordinary range of distribution to a 

 species solely on the basis of these " Lobb, Columbia " specimens.
